Piezoelectricity Question....

[hypersoniq]

couldn't find that penn state article, but here is a great primer on all things piezoelectric (with emphasis on ceramics, lots of useful numbers and formulae in the tutorial) http://www.americanpiezo.com/piezo_theory/index.html

piezo crystals are not very strong, it's that very property that allows the compression in the first place. piezo ceramics and films are showing promise since they have higher output and greater mechanical strength.

Ok now I got a closer look at your system.  I think you got it reverse.  The crystal is suppose to be sandwich between the conductor.  Let me see if I can come up a design.

got it

check my 10 min invention out lol

No you had it right the 1st time, I just omitted the box it would be put into (2nd conductor).
(That's what i get for 5 min. instructional graphics.)

I do like your wave device though, that is the only ocean wave generation idea that's made sense to me besides the damming of coves and harbors @ high tide to use the captured seawater as an propellant for generator wheels.

Could you also have crystals w/ conductors on the sides to reap the side to side impact of the roller weight?

Oh alright, then your device would work.  We just need to improve on our impulse.  The abrupt change in pressure is the key to victory.  I would change my balls into balls with spikes.  hehe  And I think I could take out the diode since we don't need direct current to generate electricity.  You should just forget about the peizo and turn your device into a pure wind generator.  Make the rod hella high to amplify the swing.  That's ton of free torque for use on the ground.  Matter of fact, keep on doing the peizo, I'll steal your idea to make wind generator. hehe

Only if we get a hold of some big peizo crystals.  Meanwhile, we'll just play around with design until our time come. lol

Let me see if I can amplify your device and turn it into a machine
