Hi @SatyaSai-TCPL, thanks for the questions! The current rating is unknown. The size of the battery after folding it in half and laminating it together is ~85 mm x 90 mm with a thickness of 0.75 mm. And unfortunately it is not rechargeable. Hope this helps!

Hi @frederickmak1, thanks for the question. We offer an insulator ink on our store: store.voltera.io/products/aci-ss1109-2ml-cartridge-copy?_pos=7&_fid=bb86ae1ba&_ss=c.

Hi @platin2148, interesting idea! We'll have to try it out.

Hi @CryogenicRig, thanks so much for flagging that! The link in the description has been updated.

Hi @euancockburn5776, thanks for the question! The V-One drills holes for vias, and then rivets must be inserted manually to complete the vias.

Hi @lmamakos, thanks for the question! V-One is designed to help you create multiple iterations of a PCB in a single day, usually for R&D and educational purposes. Once you've locked down a design, a stencil, as you mentioned, is quickest for bulk printing.

For the sake of what, saving $5 on a stencil?

​@@MSM5500but I like doing it the harder and expensive way. Imagine a $100 NE555 pulse generator. Cool isnt it?

Hi @bzmgames1308, thanks for the suggestion! We'll keep it in mind. For now, feel free to check out other videos on our channel featuring V-One

Thanks! V-One is currently on sale for $3,699.99 USD until the end of January. You can purchase it here: store.voltera.io/products/v-one

Glad you enjoyed it!

Thanks for your kind words @Intech1200!💚 This printing method is called direct ink writing. If you're curious about the details of this project specifically, we documented it in this white paper: www.voltera.io/application-whitepapers/printing-magnesium-zinc-battery-saral-inks-pet

Hi @markhesketh6699! Thanks for the question. You're right - both machines can create PCBs relatively quickly, but there are a couple key differences. V-One has the additional feature of being able to dispense solder paste and has a heated bed for reflow, giving it more functionality for PCB prototyping, whereas the CNC Wegstr can only do milling. Prototyping with V-One will be quicker since there are less steps than a milling process. And since V-One uses additive manufacturing, you can wipe away any print iterations you don't want to use and start fresh on the same board. With milling, you'd likely need to use a new board for each iteration, which adds up the more iterations you need to do. If you have any further questions or want to discuss your specific application, don't hesitate to reach out to sales@voltera.io. Hope this helps!

Hi @imrphysicist6265, the fabric is cotton

@voltera_io what type exactly

@@imrphysicist6265 It was standard cotton quilting fabric. Hope that helps!

Hello @AishwaryaBMudennavar-t9u! Our team often uses KiCad. Hope this helps!

Hi @imrphysicist6265! The substrate is TPU, and in the step you mentioned, we removed the TPU from the carrier that we left on for the printing steps. The TPU can be found on our store: store.voltera.io/products/intexar-tpu-5-sheets?_pos=1&_sid=1916b7123&_ss=r

Hi @sampugh6404, NOVA can work with an ethernet connection (does not need a wireless connection). Feel free to reach out if you have any further questions!

Hi @imrphysicist6265, we used ACI Materials’ SS1109 stretchable silver ink. Our specifications for printing on NOVA were: Dispense = 5080 and Relief = 5030 (although the material was already calibrated in our materials library on NOVA's software). Let us know if you have any further questions!

Is it possible to do pdms printing with voltera? Any thoughts

Hi@@imrphysicist6265, it is possible to do PDMS printing with NOVA, however we would recommend contacting our Technical Representatives to make sure the materials you have in mind fit NOVA's specifications. You can contact them via sales@voltera.io.

Hi @monir1490, you can find the price on our website: www.voltera.io/v-one

Hi @neginfi3649! The design of the pattern was inspired by this research paper: pubs.aip.org/aip/apr/article/10/4/041408/2919081/Dry-electrode-geometry-optimization-for-wearable. We used KiCad to design the electrode.

You can see the white paper for this project on our website: www.voltera.io/application-whitepapers/printing-ecg-electrodes-biocompatible-gold-ink-tpu

Please reach out to support@voltera.io.

It could be due to a variety of things, including a bad batch of material, too much moisture, or improper storage of the material. It's important to follow the storage and handling recommendations found on the material's technical data sheet.

Sorry to hear you experienced issues with your V-One. Have you reached out to our support department at all? You can reach them at support@voltera.io. That is not the correct price for NOVA - the machine is not that expensive. If you'd like to build a quote, we would be happy to help. Just reach out to sales@voltera.io."

In addition to the info in the video, here's a blog with more on solder paste: www.voltera.io/blog/what-is-solder-paste

Can you email us at sales@voltera.io? We can connect you with our distributor in India.

This is a 5cc Nordson EFD cartridge filled with silver conductive ink. We sell the ink and the empty cartridges on our online store: - Clear: store.voltera.io/products/replacement-cartridge-pack?_pos=11&_sid=4136c8099&_ss=r - UV blocking: store.voltera.io/products/empty-uv-blocking-cartridge-pack?_pos=12&_sid=4136c8099&_ss=r - Silver ink: store.voltera.io/products/conductor-3-ink-cartridge-2ml?_pos=1&_sid=4136c8099&_ss=r

Hi Zuulaika, thanks for your question. We used PET in the video and it was not treated. You can find the PET we used here: store.voltera.io/products/pet-5-sheets

Interesting! NOVA can definitely be used to dispense solder paste, but may not suit your exact application well. Would you be able to reach out to us at sales [at] voltera.io?

We're not too sure. This research was conducted by Yoland El-Hajj at York University in Toronto. She did detail some of her process in her research papers: www.researchgate.net/publication/361717600_Inkjet_and_Extrusion_Printed_Silver_Biomedical_Tattoo_Electrodes and yorkspace.library.yorku.ca/server/api/core/bitstreams/77423903-d210-46d3-9387-bdec086bd6cb/content

We'd be happy to learn more about what you're working on. Please reach out to us at hello@voltera.io.

This is not a CNC machine. It is an extrusion-based direct-ink-write system. It is for companies that are rapidly iterating and prototyping numerous PCB designs each day. If you are only making one PCB and can wait to receive it in the mail, then V-one might not be the best option for you.

This particular project wasn't for glucose monitoring, but there are many different biomedical applications for technology like this.

Sounds interesting! Please send an email to applications@voltera.io!

Some of our users are developing implantable devices! It's cutting-edge research!

Thank you for watching!

The graphing program used is MegunoLink.

The V-One can print conductive pastes in the screen printable (higher viscosity) range. It can also print solder paste.
