Is anyone racing on piezoelectric boards?
Pebu: Yeah, it's the stress in the material that creates a voltage. I don't know if you can get much current though. And if you apply a voltage across the material you induce a stress in the material, so it works both ways.
Their description is what is goofy. They talk about the piezo effect controlling circuits and "microchips" and doing all kinds of things. How are they running these IC's? Are there storage capacitors built into the board, or a battery embedded into the structure? Where is the power to dampen the board coming from? Another set of piezoelectric elements? So one set of elements generates the power through bending action, and another set dampens the vibrations, and in-between there is voltage rectification and regulation, some active control circuitry, and even a light? The piezoelectric effect is real and useful but the way they are describing the system sounds really gimmicky, like those shoes with the lights on the heels. If one set of elements was hard-wired to another set of elements with no crap in between, I could believe it, maybe.
Couldn't you do the same thing with pockets of shot embedded into the board, like a dead-blow hammer? Someone ought to try that. EDIT: I know it's note really the same thing, but it would be fun to try it.
