Hi I would like to know a few examples of materials which exhibit piezo-electricity and are also transparent, and could they be purchased online or synthesized at home with ease. Thanks a lot
The top of my list for exhibiting piezo activity and can be easily purchased and is also transparent..
That's about it. It's used everywhere - as an oscillator for quartz crystal watches, quartz crystal microbalances, etc.
Most of the other piezoelectric options:
Aren't transparent. They're white ceramics. You can easily purchase them online from most scientific supply companies, but they don't meet your transparency criteria.
Polyvinylidene difluoride (PVDF) is claimed to be transparent (e.g., here) but you would need to apply a high electric field to pole it, and if the formulation isn't crystalline enough, you may not get a high piezo response.
My group is designing some materials that would be good, but they're still in the research stage. Stay tuned.
