You can purchase them on Amazon! It depends on your country, but if you search piezoelectric, you will find many options.

It would be ceramics (for the same design). I found a good overview article on piezoceramics at: piceramic.com/piezo-technology/fundamentals.html Another webpage that might be helpful is: www.researchgate.net/post/How_much_current_could_be_generated_by_means_of_a_single_piezoelectric_crystalA couple of answers from this page that are relevant: “I have just a point to add here that the piezoelectric single crystals (PZN-PT) are superior to ceramics (PZT) and polymers (PVDF) for their high piezoelectric coefficients at room temperature. It should be noted that the higher coefficients doesn't mean higher power in all the circumstances. Knowing the application one should carefully design the transducer. As said earlier the output is the function of dimensional parameters, piezoelectric, mechanical and dieletric properties of the material.” “The maximum current, voltage and wattage, all parameters are depending on the type of piezoelectric material (Quartz, PZT, PMN-PT), size of the material. If we take the example of PZT, the maximum current can vary from nA to micro amp and the voltage generated in 1-100 V, depending upon the size of PZT.”
