Piezoelectricity Experiments. Help Needed! Answered
I'm currently experimenting with piezoelectricity.
And at the moment my experiment is limited to just a few piezo sparkers extracted from cigarette lighters.
The sparker works with observable voltage spike on my multimeter. No voltage spike however when I use the tiny crystal (the size of a zippo flint) taken out from the sparker.
I was trying to replicate this experiment (without the oscilloscope):
Piezoelectric Rochelle Salt
Another thing, Would continuous vibration produce continuous voltage?
It is known that piezo crystals produce high voltage, yet very low current. What are the options to increase the current? Would winding un-insulated copper wire around it (or any kind of contact with conductive metal) increase the current?
Apart from lighter, what other surplus sources of piezoelectric crystals (i.e. quartz, PZT, Rochelle)? Can the crystal in RC toys, radios be used to generate electricity?
Although there is the option to grow my own Rochelle salt, I'm not looking into it at the moment since it's going to take quite a while to grow.
Thanks in advance!
