now the question remains, is a voltage being produced by the impulse or impact from compressing/deforming and relaxing the crystal, or do you think a constant pressure would yield a constant voltage?
@@GabrielCazorlaPersson1 - Are you familiar with the Earthtide theory as the mechanism for Earth's magnetic field? Imo it makes more sense than the core dynamo hypothesis. The gist is that 95% of the Earth's crust is quartz-based, and that tidal forces from the Moon produce a diurnal flexing on the Earth's heavily faulted crust, which generates a piezoelectric field - "magnetic field" is a misnomer. Anyway, it solves many of the mysteries associated with the field and provides predictive ability whereas the dynamo theory does not.

@@jeffv2074 I won't say Chakras definitively don't exist, but you should at least respect it's not the same realm of hard science that this video covers - i.e. directly quantifiable materials physics. At best it's a "softer" or more holistic science closer to the realms of medicine or neurology/psychology. And even within that realm the notion of Chakras is not super well supported in any sort of large scale, peer reviewed, replicable study (that I know of). Which again, doesn't mean it's wrong necessarily, but it's entirely understandable why some people would have doubts about it. At the very least wouldn't be as condescending towards skeptics as you're being. You might be surprised to learn there's a lot of very intelligent people who don't believe in Chakras. Granted I also know plenty of intelligent people who *do* believe in chakras and various other spiritual/semi-spiritual concepts. But even among the latter group I've met, I don't think any ever claimed that there's convincing concrete research behind it at the moment.
If you rub two quartz together it produces a really cool lighting effect, that jumps through the insides of the stones. Very very cool, I use it when camping to make my friends think I’m a wizard

@@SteveMould Peanut butter is the best. I like the natural kind. Except for when you first buy it and have to wear out your arm stirring it. That part sucks.
Which is funny, because “electric” is also from Greek - electros, meaning amber, since static electricity was first observed by rubbing silk and amber. So, it means “I compress amber”
@@bhogarsishyan5769 Fooling manipulable people is not funny, we are not laughing. The fact that people buy these is seriously concerning, as it is not "alternative medicine", it's just a placebo, and for a high price. Accepting the existance of things like chakras without any sort of evidence for them is very childish, same with other dogma. Scepticism is the thing that makes the scientific method the best way to obtain truth about our surroundings: constantly checking if you are wrong, not if you are right. Once you realize that "alternative medicine" (like crystal-healing and homeopathy, etc.) is not medicine, simply a psychology trick to take your money, you might actually start learning that the world is not so simple.

1:57 fun fact: when you take a rock with lots quartz in it (say, a large chunk of quartz) and rub it against another rock (it's best with another large chuck of quartz), the quartz will make a dust (that is *hazardous to breathe in* ). Those tiny flakes break in such a way that rubbing them will create light. 👍
U reminded me of my high school teacher who would go extents, to make students understand the beauty of science in everyday things. Loved it man. Excellent work.😊
It's good to see that you don't try and impress your audience by speak too quickly like most UA-camrs. Your teaching is very good because of this. You take the time to explain things in detail. It's about time a UA-camr had the sense to know that an audience learns better when a teacher explains things at a slower rate than other UA-camrs priding themselves at how quickly they can speak.
Thanks! This is clear and helpful. Perhaps you can find some places on the Internet where they do know the angles, and they do know the equations, and they do know the charges and voltages as a function of pressure. And put them into your description. When you have millions of viewers, you have a greater responsibility to find and share real data, models and methods. Not just words and pictures of explanations. Give people tools to make and use things precisely, not just words about ideas. Thanks. Richard Collins, The Internet Foundation
My friend... I'm 34 and I've tried to mentally visualize how this stuff works, and I've watched many videos in my time on UA-cam, but you nailed it. This is amazing! I am gonna watch more of your vids and subscribe!
In the absence of referencing a textbook for confirmation, I thought this was a very succinct explanation that would be a great starting point for anyone interested in this effect. Thanks for the great work, Steve! Keep it up 👍🏻
Dude your videos are SO GOOD I knew of the piezoelectric effect and had been explained it, but you do it in such a clear and concise way, it's great to listen to and finally be able to internalize it. Thanks a lot!
@@codpug You're lying to yourself and you're lying to the world when you say these things. Nobody is trying to hide history, what would anyone have to gain from that?
I'm a biologist, but our confocal microscopes also make use of the piezoelectric effect. To adjust the focus, there are of course mechanical gears that adjust the position of the objective relative to the sample with exquisite precision. But for some application where both speed and even higher precision are needed, microscopes can be outfitted with a piezoelectric focusing system. The range of motion is smaller, but the objective can be moved tiny amounts with a precision down to 10s of nanometres within microseconds. This is especially useful for certain modes the microscopes can use, such as resonance scanning mode, which allow us to capture images at very high speed in the xy plane. The piezoelectric focus adjuster gives us a matching fast way to adjust the z-plane. I don't know which specific materials they use, but the principle is the same. By applying a specific voltage, the crystals deform in length and can be used to position the objective.
Fantastic video, as always. Another interesting use of piezoelectric crystals is when you need extreme accuracy in the measurement of distancies (for example in interferometers), by applying a small voltage to the crystal you can shift it's length with a resolution of a fraction of a nanometer (10^-9 meters)!
Loved this video. It's hard to put my finger on it, but there seems to be a sense of excitement and wonder about scientific discovery that Steve just exudes, and its totally contagious.
Amazing explanation! Thank you. Many years ago my 8 year old son asked why two quartz rocks make sparks when you bang then together. I had him forward his question to a CBC radio science program. Their "expert" gave a totally unsatisfying answer. You sir, have satisfied my curiosity! I'll forward the link to this page to him....I'm sure he'll appreciate your explanation.
Thanks, I've worked in electronics almost sixty years, never pursued this answer, but find it quite logical and reasonable. Thanks, I enjoy your videos.
I always assumed lighters just used a flint striker to make the spark that ignites them. I never considered that peizo electricity would be easier/cheaper/better than a basic friction striker.
I remember an old interview with guitarist and multi-instrumentalist David Lindley, talking about having used earthquake sensors, little piezoelectric discs, as guitar pickups.
@@Enrique-peralta , since piezoelectric crystal's produce voltage when vibrated, you can stick them inside the body of an acoustic guitar and they will pick up the vibrations of the wood, which is somewhat analogous to the vibrations of the strings. The trick to getting a good sound, of course, would be placement of the piezo pickup, or pickups (plural), and whether you blend it with some kind of internal or external microphone or even a magnetic pickup that senses the string vibration directly. At least one company makes piezo type pickups that go underneath the bridge saddle and have six individual piezo crystals for the contact points of the six strings. I don't know what the favorite pick up systems are now, but back in the 80s and 90s Sunrise and Fishman, and to a lesser extent Barcus-Barry, were the ones that people were mostly using. I believe at least one of these systems had an internal microphone as well as the piezo pickup.
This is amazing. I am so fascinated with Quartz. It is mind boggling what this stone is capable of. This is not just a shiny stone! Thank you for making such wonderful and educational videos. I have been hooked to your channel. I will also subscribe to curiosity stream. We need more science channels like these on youtube! Thank you.
I dont think it is true but it may be possible I guess we use the resonation of quartz to keep time so what's to say other stones done resonate in some way.@@easygrows2699
I actually use piezoelectric actuators a lot in my work, but I never pay attention to how it actually works in molecular level until I saw this video. Thank you for the effort!
Do you do MRI-compatible neurorobotics? My buddy Greg Cole did his master's thesis designing a piezo actuated brain surgery robot that had less than 1% MRI signal interference. They're loud as anything
@@natheniel it's a pickup for acoustic instruments, like cello or acoustic guitar. Idk exactly how it works, but by the name I'm guessing it's the piezoelectric effect.
As the vibrations travel through the crystalline structure theres compression and expansion happening, producing an electric voltage. Well, something along those lines anyways.
@@natheniel Also known as contact microphones, they are used to pick up only the sound from the instrument/object they placed in contact with, not picking up surrounding air vibrations like an ordinary microphone, isolating the sound.
The sound waves (aka compression waves) in the instrument's body make its way to the piezo pick-up and consequently compress it, in turn generating an electric signal which is then sent to an amplifier. Piezo pick-ups work better when they have direct contact with a hard surfaces as you might've guessed from this video.
MR.MOULD, YOU HAVE NO IDEA HOW NUCH I LOVE YOUR VIDEOS AND HOW MUCH YOU'VE TAUGHT ME AND KEEP EXCITED ABOUT THESE PHYSICAL PHENOMENA. I'm a dentist and we studied about the piezoelectric theory in orthodontics (braces work). Yes piezoelectric happens in your body too, but i never quite understood what it really was. There are a lot of stuff we study and just get over it not actually quite going into the depth of each phenomena (for understandable reasons) and i wpuld stop and think about them. Somehow too often i end up finding a video of yours explaining the phenomena and satisfying my curiosity. So thank you Mr. Mould. I've a deep passion for learning. Alhamdulilah.
this is a great video. Thank you for explaining why the butane long neck lighters are difficult to light (but you left out another main reason, they make them child proof now, lighters weren't that hard to light years ago, they didn't have the extra safety button you have to hold, so that factors into it). I bought a piezo electric long neck lighter about 5 years ago (primarily to light candles in glass candle holders where a smaller lighter won't reach), it works great, never have an issue lighting candles. Before having the piezo lighter, I used to go through many butane lighters, they would stop working quickly (even after refilling with butane).
100% i often remove the extra safety spring or try use a rly old lighter it annoys me i have to consider safety! Theres no kids getting it how about teaching parenting rather than making laws about safety lighters that then inconvenience me for a kid who dont exists safety! I hate the after 2000s world so much lol!
Can you make a similar video to this, but for thermistor? They're used in 3D printers all the time, and I understand what they are, but I have no idea how they work. If you don't know what a thermistor is, let me whet your appetite. When things head up or cool they expand or contract, right? And different materials expand or contract at different rates. So what happens is you take two different metals and put them next to each other, or even better, weld them, then heat or cool them? Well, one expands and contracts at one rate, and the other expands and contracts at a different rate, and it may curl, just a little bit? Even more interesting than that, there is a change of resistance across the connection. If you put a current across the metals, and measure the current drop on the outward side, you can use that to determine the temperature. I know, right? It blows my mind, too. But these are used all over the place and what's going on makes no sense to me.
Acoustic guitar pickups use them also. By picking up the vibrations of the guitar and turning them into an electrical charge that's played through a speaker as music.
Just finished a 4 year electrician apprenticeship. I was today years old when I learned how the piezoelectric components I've been working with actually function.
You put so much work into each video, don’t let anyone tell you eating peanut butter isn’t work. I learned about lattice structures and piezoelectric crystals on Star Trek.
Found this randomly. Being a "science guy" im always interested in this type of stuff. Now i finally understand piezoelectricity. Good balance between information density and approachability. (for lack of a better word) Subbed!
Strangely enough, I'm guessing people got a slight shock or tingle, when striking a crystal, and so thought there was some kind of ''magic'' energy inside them. That's probably how they first started being used as ''healing crystals''. Turns out that magical energy was just electricity. 😏
@@KaityKat117 that is what happens when you are IGNORANT on something, LOL. quartz are used in almost EVERYTHING. it has ENERGYm yes, so if science does NOT KNOWS how to study its effect in AURA, or chakra or human energy field or CHI, then it means THAT science is limited and archaic, since many countries MEDICINE and SCIENCE uses CHAKRAS and CHI to help the body heal faster...... but seems here we have 5 ignorant human lemmings, so sad..... science, sometimes its just science..... and science DOES NOT explains everything...... so sad...... some people seem they are like a religious science organization, very limited mind.
Peiezoelectric pick ups for guitar is the first thing that sprung to mind. I remember faffing about with a speaker when I was a kid, and realising that it worked as a microphone. I love this guy's videos.
It will only open your third eye and align your chakra colors with the magical powers of its piezoelectricity if you *INSERT IT R E C T A L L Y* !!! One of the most exotic and nonintuitive uses of the effect is for making electron beam evaporated optical coatings on glass. Little wafers of PZ quartz are located in the vacuum chamber near the glass and the change in resonance frequency of the crystals corresponds exactly to the amount of reflective material that's been deposited thus far. It is exquisitely sensitive, nearly being able to sense the weight of individual atoms and is able to detect coating deposition rates of mere angstroms per minute.

Your brain can be considered as an electrical powerhouse, given its amount of connections, wiring and power consumption. Well, in fact, no, not a powerhouse; but rather something electrical, big, and complex. And stress surely increases brain activity.
My favorite example is the record player stylus, this shows just how amazingly accurate the pressure to electricity actually is. I can hear every note of the entire band of led zeppelin or every subtly of Benny Goodman king of swing.
@@sed6 right a photograph is a non electric device that just has a metal stylus that vibrates a diaphragm that the shape of the horn amplifies acoustically like a horn.
Very cool to see material science getting some love! Piezoelectricity and similar concepts that are driven by spontaneous polarization play an important role in a lot of things we use everyday!
@@I_SEE_REDhaha that will do the trick, I remember my cousin when we was younger his brother took a cassette player apart and his bro came along plugged it in to the mains as he still had it in his hands taking it apart and he had the best shock of his life 🤣
I guess it must be, because it seems that electrons can't travel easily through the crystal. If they could they would just do it the first time. I think this is a really interesting question though
Any charge that flowed as a result of compressing the crystal will have to flow back when you release it. You can actually find spark lighters that use a different mechanism: instead of a springloaded hammer, you simply compress the piezo crystal via a lever. These will produce multiple sparks as you compress the lever, and just as many sparks as you release the lever. (Though I'm not sure whether a second _voltage_ spike will occur in the more common hammer-strike style devices. It seems conceivable that the air might still ionized, in which case the charge can flow back without much resistance hence no significant voltage is produced, just a current spike. It'll depend on how briefly the hammer-strike applies force and how long it takes for the ionized air to recombine after a spark, and I have no clue about either of those.)
WNT enzyme cascade is stimulated by jumping. Dancing is part of our DNA. Tomato family plants and rice also stimulate WNT. Ankilosing spondylitis and arthritis is overstimulated WNT enzyme cascade causing excessive growth between the joints causing stiffness or bone spurs. Its a Laplander gene. Alcohol and certain herbs decrease WNT. Fetal Alcohol syndrome is lack of WNT while certain cancers are stimulated to grow by WNT enzymes. Its interesting in being a chemical and physical switch. I traced the cascade from endvto end in about a day of research writing it down as I went and was so excited I took a picture. Googled some more and found the Novel Peace Prize had been awarded to the guy who got there first! ( which is why I was able to follow it through no doubt!) Still a fun day! Ill have to read up on the piezoelectric mechanism involved!
liked. subbed. when you said the video was already getting too long, I was like, what? no, it's not! more! more!! 😉 I could listen to your explanations all day. in fact, I'm going to watch the rest of your channel & literally do just that. lol.
What I don't understand at 4:46 however is why the electricity isn't travelling through the shortest path which would be the green rectangle and not the wire. I guess it is not electronically conductive and the wires are but I'm not sure how that works yet... On to googling more.
The human body has what is called the human bio-energy field that is electrical based which quartz crystals and their piezoelectricity can be used to beneficial affects if used correctly with it. There have been a lot of "new agers" who were sensitive to its affects, but never really understood why.
@@So1othurn lol it doesn't matter where what you said specifically belongs its still bullshit, it isn't science and you most likely couldn't demonstrate any real results in reality fool
I have been trying to understand the piezoelectric effect at this level (atomic) ever since I first learned about it. This is the first time I've felt like I've understood it. Great video.
@slayo 66 I believe those use a different approach, with magnetic fields, but I am not sure exactly how. And that's why if you use nylon strings on an electric guitar you won't get any sound.
@slayo 66 Electric guitar pickups have weak magnets surrounded by coils. (Or maybe just 1 coil.) When the steel strings vibrate, the magnetic field varies with them. The coils produce electricity in response to the variations in exactly the same way as the coils in a car alternator or power station generator, but obviously at a much weaker level.
Step 3: Store the electricity Step 3.5: Use the stored electricity to an electric hammer that uses only a tiny bit of electricity to hammer the crystals (Impossible?) Step 4: Unlimited Electricity
@@Slay_No_More Oh yea; you can find an article about them on wikipedia. Basically you take a coil of wire, a capacitor, a crystal detector, and earphones to make a simple radio. Moving the contact to different spots on the coil lets you receive different radio frequencies. Some companies sell little science project kits of them
Enjoyed this video! I have some questions. What happens if you continue to compress it forever? Can it "run out"? I assume that after the crystal initially deforms, the current equalizes and then it "reforms" and an equal and opposite current flows back? If this is true, is it observable? (paging slowmoguys or smartereveryday...) Second, assuming it doesn't "run out", and it's converting the mechanical energy into electrical energy, can this (is this?) used as a generator?
don't break your crystal! :P you can Make piezos at home in a double boiler with cream of tartar + borax check out laser sabers concrete batteries, I think he cooks them with similar ingredients but also a core piece of metal, I'm guessing the heat is where a lot of the battery's juice comes from. There's a few videos that show getting power from speakers, You can hook an LED up to a small speaker and tap the speaker quickly to get the led to flash briefly to prove to yourself it works, same thing with little dc motors and lights/ or to c heck if a small speaker works you can put the motor + / - to the speaker and twist it, it makes a gravelly noise lol. with power systems it always seems about making it convenient to store / convert the power lol. search "gravity battery" there are two cool results that pop up, one from Destin on smarter every day (paging mr opal boi ) and the other is a grandfather clock mechanicsm hooked to a gallon of water that plays a record on an old school turn table lol.
It doesn't run out, because you don't push electrons out of the crystal (they are fixed to their atoms). And yes the same happens in the opposite direction. Also yes, it is used as a small generator, mostly in something called for "energy harvesting" (meaning you get energy from something that is bending/pushed/vibrating). The ideas are more of a concept though because the power produced is so low that it's barely useful. But in a sense it is already a generator producing a spark.
You can only compresses it so much before it cracks... But if you're asking how reusable it is, piezoelectric crystals are subject to fatigue just like everything else. If you push it too hard for too long, it will eventually crack.
Piezo electricity is used as a generator although it's not super common yet. There have been ideas like putting pressure plates in stadiums and subway stations where all the energy from people walking over it could be captured and used to power the building. I think a few prototypes have been built but it's not a common technology yet.
Steve, thank you for helping me to understand,( what would have been) something waaay too scientific for me to grasp, by keeping it simple, to the point, and the visuals. (I loved the peanut butter lids) I am a crystal collector and I have recently become very intrigued by orgonite crystal pyramids (have you heard of them?) and how they work. I was skeptical as to if a man made construction as such could actually produce piezoelectric energy as they claim, and thanks to this video, it all makes sense. 👍🙂.
Some people believe the pyramids in Egypt were power plants. They say the outside was an insulator, and the inside was a conductor, and when the ground water would rise and fall, energy was generated. That may be a reason it was such a huge accomplishment. Idk about the crystal pyramids, but I'll check it out.
@@kg-WhatthehelliseventhatThere was an outer shell covering. I think limestone and gold on the top. Maybe the inner chamber was filled with Amber and/or copper ingots, bronze etc....as a battery OR maybe they had discovered the alloy of nickel and tin- NITINOL! and used that to move stones or the barges carrying the stones. I had a huge brass candelabra that just bent on its own one day. Sh!# just sometimes happens. I read about bronze statues that " moved " also. It was still very creepy! Turns out I live on top of ancient mineral deposits of calcium and magnesium that have a strong negative charge surrounded by stuff brought up from deep underground when Africa and North America split. That stone is filled with feldspar crystals quartz, pegmatites, garnets etc.... unfortunatly radioactive too. Camerons line meets Stockbridge limestone right at the street sign down the street! My town actually lit up red as a top energy absorber when the last solar storm hit. My little dolimite hill surrounded by water might react to and absorb solar EMF better than other areas. Maybe such a charge reacted with and bent my candelabra. The candelabra that bent some years back, mysteriously bent back again years after when I wasnt watching. Thats why I'm kind of speculating it was a solar event since its timing corresponded to the solar cycle. The good news is, I think I can let the kids off the hook now! Theory 2 was kids knocked it over -and or landed on it! - then just put it back like it wasnt them and denied it! I kind of knew it wasnt them especially after it went back! There are stories of this happening to other objects like bronze statues and most likely is I just have a candelabra from a batch of brass mixed by the new guy who put a bit more nickel in than he was supposed to! They probably had all kinds of complaints about all those bendy candelabras! Hot and cold will make Nitinol bend - I imagine EMF will too. I think I have a nitinol rich brass candelabra! Rare EMF events on candelabras in odd negative geological zones maybe will do it too. Nitinol wasnt discovered until recently as far as we know. The secrits may have been found earlier but list. Somewhere in the Brass City where my candelabra was made is some old guy who knew about it for years who will tell you they all knew about it happening but just chucked those wiggling brasses back into the pot to melt back down. Who wants wiggling bending brass! Back in time, tin was the prized metal for bronze but then became in short supply. Someone probably stumbled on Nickle or Nickle Tin ores. As far as piezoelectric crystals, electrical charge and storage, Egyptians did know much about oxides and salts, which are crystals too. They have many mineral oxides and salts on the soil surface from precipitates drying out after heavy rains. They also produced glass/ enamels and metals. Both use oxides and salts especially for pigments. They used the highly conductive metals, copper, gold and silver and the alloy electrum. Somebody could have discovered things then that were lost later on. If the pyramids were electrified, it was probably to keep people out- like electrified fencing does today! Unfortunatly the gold sheets and grave goods were too tempting- the charge too weak to kill! Times also change and events can change the earth. We just had a very strong rare gamma ray burst hit earth on October 9th 2022, GRB10092022. We now know even stronger ones hit earth in the past. The same for Carrington type events. Maybe at times the earth gets more charged like a battery after some big events, then looses the charge. A few huge events are showing in dendrological records that make the Carrington Event look small. We might have had more energy in the ground then or possibly less charge that would have produced different electrical effects. Some effects may have worked then but not now. Not enough charge in our ground. Im still thinking the pyramids were built using the slip method. Its a lot more low tech and so not so sexy! I came to that conclusion the hard way -after slipping on a clay soil pathway carrying a huge boulder right after it started to rain! One step on the slip that formed from the rain took me down like the slipperiest wet ice! Slip can form a viscous surface with incredible properties. Its clay that has been shaken. No more water in slip than in clay. Heavy things like rocks (or people carrying rocks) glide across it like wet ice. Buildings built on mud flats sink as clays liquify to slip during earthquakes. The clay hardens then holding them up again. Somewhere in between the two forms, solid and liquid lies the slip viscosity that can hold stones up off the surface while allowing them to float across with ease! Anyone want to try experimenting with stone moving!?
The energy to hit the crystal will be more than the electricity it can produce. Would be interesting to see how efficiently it converts to energy though. Could be more efficient than some other forms of transferring motion into energy.

Interesting fact:
"Piezo" is a greek word ( Πιέζω ) meaning "I compress"
Which, in narrative terms, is approximately the opposite of "I digress".
Quartz protec
quartz attac
but most importantly
quartz piezoelectric
Which is funny, because “electric” is also from Greek - electros, meaning amber, since static electricity was first observed by rubbing silk and amber.
So, it means “I compress amber”

Scepticism is the thing that makes the scientific method the best way to obtain truth about our surroundings: constantly checking if you are wrong, not if you are right. Once you realize that "alternative medicine" (like crystal-healing and homeopathy, etc.) is not medicine, simply a psychology trick to take your money, you might actually start learning that the world is not so simple.

I'm a biologist, but our confocal microscopes also make use of the piezoelectric effect.
To adjust the focus, there are of course mechanical gears that adjust the position of the objective relative to the sample with exquisite precision. But for some application where both speed and even higher precision are needed, microscopes can be outfitted with a piezoelectric focusing system.
The range of motion is smaller, but the objective can be moved tiny amounts with a precision down to 10s of nanometres within microseconds. This is especially useful for certain modes the microscopes can use, such as resonance scanning mode, which allow us to capture images at very high speed in the xy plane. The piezoelectric focus adjuster gives us a matching fast way to adjust the z-plane.
I don't know which specific materials they use, but the principle is the same. By applying a specific voltage, the crystals deform in length and can be used to position the objective.
Fantastic video, as always.
Another interesting use of piezoelectric crystals is when you need extreme accuracy in the measurement of distancies (for example in interferometers), by applying a small voltage to the crystal you can shift it's length with a resolution of a fraction of a nanometer (10^-9 meters)!

I remember an old interview with guitarist and multi-instrumentalist David Lindley, talking about having used earthquake sensors, little piezoelectric discs, as guitar pickups.
What is this? Something to record the guitar from inside?
@@Enrique-peralta , since piezoelectric crystal's produce voltage when vibrated, you can stick them inside the body of an acoustic guitar and they will pick up the vibrations of the wood, which is somewhat analogous to the vibrations of the strings. The trick to getting a good sound, of course, would be placement of the piezo pickup, or pickups (plural), and whether you blend it with some kind of internal or external microphone or even a magnetic pickup that senses the string vibration directly. At least one company makes piezo type pickups that go underneath the bridge saddle and have six individual piezo crystals for the contact points of the six strings. I don't know what the favorite pick up systems are now, but back in the 80s and 90s Sunrise and Fishman, and to a lesser extent Barcus-Barry, were the ones that people were mostly using. I believe at least one of these systems had an internal microphone as well as the piezo pickup.
I thought they worked by em induction, oh i guess multiple types.

Me at the beginning: "Piezoelectric," sounds like a Piezo pickup.
Me at the end when you used it as a microphone: OH THAT'S WHY!
Logan Strong Hi I’m an elementary audio guy here, what does a Piezo pick do?
@@natheniel it's a pickup for acoustic instruments, like cello or acoustic guitar. Idk exactly how it works, but by the name I'm guessing it's the piezoelectric effect.
As the vibrations travel through the crystalline structure theres compression and expansion happening, producing an electric voltage. Well, something along those lines anyways.
@@natheniel Also known as contact microphones, they are used to pick up only the sound from the instrument/object they placed in contact with, not picking up surrounding air vibrations like an ordinary microphone, isolating the sound.
The sound waves (aka compression waves) in the instrument's body make its way to the piezo pick-up and consequently compress it, in turn generating an electric signal which is then sent to an amplifier. Piezo pick-ups work better when they have direct contact with a hard surfaces as you might've guessed from this video.

I bought a piezo electric long neck lighter about 5 years ago (primarily to light candles in glass candle holders where a smaller lighter won't reach), it works great, never have an issue lighting candles. Before having the piezo lighter, I used to go through many butane lighters, they would stop working quickly (even after refilling with butane).

Can you make a similar video to this, but for thermistor? They're used in 3D printers all the time, and I understand what they are, but I have no idea how they work.
If you don't know what a thermistor is, let me whet your appetite. When things head up or cool they expand or contract, right? And different materials expand or contract at different rates. So what happens is you take two different metals and put them next to each other, or even better, weld them, then heat or cool them? Well, one expands and contracts at one rate, and the other expands and contracts at a different rate, and it may curl, just a little bit?
Even more interesting than that, there is a change of resistance across the connection. If you put a current across the metals, and measure the current drop on the outward side, you can use that to determine the temperature. I know, right? It blows my mind, too. But these are used all over the place and what's going on makes no sense to me.

One of the most exotic and nonintuitive uses of the effect is for making electron beam evaporated optical coatings on glass. Little wafers of PZ quartz are located in the vacuum chamber near the glass and the change in resonance frequency of the crystals corresponds exactly to the amount of reflective material that's been deposited thus far. It is exquisitely sensitive, nearly being able to sense the weight of individual atoms and is able to detect coating deposition rates of mere angstroms per minute.

Is there a second voltage spike (in the opposite direction) when the crystal goes back to its initial configuration?
I guess it must be, because it seems that electrons can't travel easily through the crystal. If they could they would just do it the first time. I think this is a really interesting question though
Any charge that flowed as a result of compressing the crystal will have to flow back when you release it. You can actually find spark lighters that use a different mechanism: instead of a springloaded hammer, you simply compress the piezo crystal via a lever. These will produce multiple sparks as you compress the lever, and just as many sparks as you release the lever.
(Though I'm not sure whether a second _voltage_ spike will occur in the more common hammer-strike style devices. It seems conceivable that the air might still ionized, in which case the charge can flow back without much resistance hence no significant voltage is produced, just a current spike. It'll depend on how briefly the hammer-strike applies force and how long it takes for the ionized air to recombine after a spark, and I have no clue about either of those.)
there isn't. no charge leaves the crystal, the voltage is simply propotional to how hard you squeeze it

This is an amazing explanation. I have often thought about this myself, especially because a lot of acoustic guitar pickups use this effect.
@slayo 66 I believe those use a different approach, with magnetic fields, but I am not sure exactly how.
And that's why if you use nylon strings on an electric guitar you won't get any sound.
@slayo 66 Electric guitar pickups have weak magnets surrounded by coils. (Or maybe just 1 coil.) When the steel strings vibrate, the magnetic field varies with them. The coils produce electricity in response to the variations in exactly the same way as the coils in a car alternator or power station generator, but obviously at a much weaker level.

What happens if you continue to compress it forever? Can it "run out"? I assume that after the crystal initially deforms, the current equalizes and then it "reforms" and an equal and opposite current flows back? If this is true, is it observable? (paging slowmoguys or smartereveryday...)
Second, assuming it doesn't "run out", and it's converting the mechanical energy into electrical energy, can this (is this?) used as a generator?
don't break your crystal! :P
you can Make piezos at home in a double boiler with cream of tartar + borax
check out laser sabers concrete batteries, I think he cooks them with similar ingredients but also a core piece of metal, I'm guessing the heat is where a lot of the battery's juice comes from.
There's a few videos that show getting power from speakers, You can hook an LED up to a small speaker and tap the speaker quickly to get the led to flash briefly to prove to yourself it works, same thing with little dc motors and lights/ or to c heck if a small speaker works you can put the motor + / - to the speaker and twist it, it makes a gravelly noise lol.
with power systems it always seems about making it convenient to store / convert the power lol. search "gravity battery" there are two cool results that pop up, one from Destin on smarter every day (paging mr opal boi ) and the other is a grandfather clock mechanicsm hooked to a gallon of water that plays a record on an old school turn table lol.
It doesn't run out, because you don't push electrons out of the crystal (they are fixed to their atoms). And yes the same happens in the opposite direction.
Also yes, it is used as a small generator, mostly in something called for "energy harvesting" (meaning you get energy from something that is bending/pushed/vibrating). The ideas are more of a concept though because the power produced is so low that it's barely useful. But in a sense it is already a generator producing a spark.
Yes putting a fluctuating force on the crystal generates a fluctuating voltage proportional to the force for small values.
You can only compresses it so much before it cracks... But if you're asking how reusable it is, piezoelectric crystals are subject to fatigue just like everything else. If you push it too hard for too long, it will eventually crack.
Piezo electricity is used as a generator although it's not super common yet. There have been ideas like putting pressure plates in stadiums and subway stations where all the energy from people walking over it could be captured and used to power the building. I think a few prototypes have been built but it's not a common technology yet.
Steve, thank you for helping me to understand,( what would have been) something waaay too scientific for me to grasp, by keeping it simple, to the point, and the visuals. (I loved the peanut butter lids)
I am a crystal collector and I have recently become very intrigued by orgonite crystal pyramids (have you heard of them?) and how they work. I was skeptical as to if a man made construction as such could actually produce piezoelectric energy as they claim, and thanks to this video, it all makes sense. 👍🙂.
Some people believe the pyramids in Egypt were power plants. They say the outside was an insulator, and the inside was a conductor, and when the ground water would rise and fall, energy was generated. That may be a reason it was such a huge accomplishment. Idk about the crystal pyramids, but I'll check it out.
@@kg-WhatthehelliseventhatThere was an outer shell covering. I think limestone and gold on the top.
Maybe the inner chamber was filled with Amber and/or copper ingots, bronze etc....as a battery OR maybe they had discovered the alloy of nickel and tin- NITINOL! and used that to move stones or the barges carrying the stones.
I had a huge brass candelabra that just bent on its own one day.
Sh!# just sometimes happens.
I read about bronze statues that
" moved " also.
It was still very creepy!
Turns out I live on top of ancient mineral deposits of calcium and magnesium that have a strong negative charge surrounded by stuff brought up from deep underground when Africa and North America split. That stone is filled with feldspar crystals quartz, pegmatites, garnets etc.... unfortunatly radioactive too.
Camerons line meets Stockbridge limestone right at the street sign down the street!
My town actually lit up red as a top energy absorber when the last solar storm hit. My little dolimite hill surrounded by water might react to and absorb solar EMF better than other areas. Maybe such a charge reacted with and bent my candelabra.
The candelabra that bent some years back, mysteriously bent back again years after when I wasnt watching. Thats why I'm kind of speculating it was a solar event since its timing corresponded to the solar cycle.
The good news is, I think I can let the kids off the hook now! Theory 2 was kids knocked it over -and or landed on it! - then just put it back like it wasnt them and denied it!
I kind of knew it wasnt them especially after it went back!
There are stories of this happening to other objects like bronze statues and most likely is I just have a candelabra from a batch of brass mixed by the new guy who put a bit more nickel in than he was supposed to!
They probably had all kinds of complaints about all those bendy candelabras!
Hot and cold will make Nitinol bend - I imagine EMF will too.
I think I have a nitinol rich brass candelabra!
Rare EMF events on candelabras in odd negative geological zones maybe will do it too.
Nitinol wasnt discovered until recently as far as we know. The secrits may have been found earlier but list. Somewhere in the Brass City where my candelabra was made is some old guy who knew about it for years who will tell you they all knew about it happening but just chucked those wiggling brasses back into the pot to melt back down. Who wants wiggling bending brass!
Back in time, tin was the prized metal for bronze but then became in short supply. Someone probably stumbled on Nickle or Nickle Tin ores.
As far as piezoelectric crystals, electrical charge and storage, Egyptians did know much about oxides and salts, which are crystals too.
They have many mineral oxides and salts on the soil surface from precipitates drying out after heavy rains.
They also produced glass/ enamels and metals. Both use oxides and salts especially for pigments. They used the highly conductive metals, copper, gold and silver and the alloy electrum.
Somebody could have discovered things then that were lost later on. If the pyramids were electrified, it was probably to keep people out- like electrified fencing does today!
Unfortunatly the gold sheets and grave goods were too tempting- the charge too weak to kill!
Times also change and events can change the earth. We just had a very strong rare gamma ray burst hit earth on October 9th 2022, GRB10092022.
We now know even stronger ones hit earth in the past. The same for Carrington type events.
Maybe at times the earth gets more charged like a battery after some big events, then looses the charge. A few huge events are showing in dendrological records that make the Carrington Event look small.
We might have had more energy in the ground then or possibly less charge that would have produced different electrical effects.
Some effects may have worked then but not now. Not enough charge in our ground.
Im still thinking the pyramids were built using the slip method. Its a lot more low tech and so not so sexy!
I came to that conclusion the hard way -after slipping on a clay soil pathway carrying a huge boulder right after it started to rain!
One step on the slip that formed from the rain took me down like the slipperiest wet ice! Slip can form a viscous surface with incredible properties.
Its clay that has been shaken. No more water in slip than in clay. Heavy things like rocks (or people carrying rocks) glide across it like wet ice.
Buildings built on mud flats sink as clays liquify to slip during earthquakes. The clay hardens then holding them up again. Somewhere in between the two forms, solid and liquid lies the slip viscosity that can hold stones up off the surface while allowing them to float across with ease!
Anyone want to try experimenting with stone moving!?
Just curious, could this be used to make a weightscale, where you would match the crystals charge output to a force displayed in kg? Great video
Yes, I built a crane load sensor that is exactly how it works.
I was expecting someone to hit a crystal, not look like they just got done with an acid trip.
The energy generation aspect of piezoelectricity is way underrated. Especially when thinking at large scale.
The energy to hit the crystal will be more than the electricity it can produce. Would be interesting to see how efficiently it converts to energy though. Could be more efficient than some other forms of transferring motion into energy.
From 1:48 - 2:01 I was crying, the awkward transition of that topic had me rolling lol
I died at his face in 2:01 😂
Hey Steve, did you ever figure out how to use that healing crystal?
We must save my family!
My favourite application of the piezo effect is a marine depth finder. Same element acts as transmitter and receiver. That's cool. Thanks Steve.
