    Piezo question

    I got some piezo discs, hook one up to my multimeter, apply pressure to disc, get voltage, switch over to measure current, get nothing. I repeat same process with a second and third disc, and get same results. Ive seen people use these, not mine, but these same piezo discs to power an led hooked...

    Will this simple Piezo circuit work?

    Hi guys, Just wondering if this simple circuit will work as I expect it to. So this is for an engine, I'm utilizing multiple Piezo igniters to create a spark plug and I'm trying to figure out if this will work. I understand that this would be pretty easy to test I just don't have the...

    Help with basic piezoelectric generator circuit design

    Hello, I want to experiment with the properties of piezoelectric generator devices. I am looking to get a few PZT devices where I can stress / impact the material to produce current. I have concept to use multiple PZT devices where they will be stressed simultaneously. The PZT devices output a...
