piezoelectric energy

Let's just squeeze some crystal and harvest the results.

Seems like it's the thing to do these days......many are doing it.  Why can't we do it at home?

The real bang for the buck seems to be in replicating the Kowsky-Frost reverse PE effect study.....

Given the intriguing nature of mechanical standing waves and the nominal input requirements for their maintenance.....it might prove interesting to see how much energy could be gathered and rectified by piezo arrays at the end of an Alpenhorn.  Certainly not enough to power a small air compressor at it's mouth.....

My two cents on piezoelectricity would be 1) that I've read and been told that it doesn't yield that high a bang for the buck though the underlying argument has to echo Les McCann -- "Compared to What?" and 2) there are some new materials out that seem to have very high elasticity, which might have implications for piezoelectricity and 3) it seems I've read that this is being explained a dozen other ways like pn junctions and electron holes and such and 4) I love the elegance of sand being squeezed until it sends out an electrical spark, and doing it thousands of times, as with gas ranges. Pretty intense.

About the only applications I've come across for crystals are: crystal oscillators and a piezo stage we use at work to do surface mapping on various materials.  The piezo stage will move 200 x 200 um, and our transducer head keeps a slight pressure on the surface (micronewtons) while it moves and maps the surface much like an atomic force microscope, which I hate using because they are so sensitive while handling them that once you get the damn thing setup, your cantilever under the laser has already broken and you have to put a new tip in it and try again.  I digress...

I don't beleive the stage crystals expand 200microns, but us a racheting device, basically a piezo motor.
