You madlad, I don't have much to add but this would be pretty interesting if it worked. Presumably uncooked bone? I also think that using a very thin slice would increase the strength of the electric field, since you want to have a small gap between the plates (field strength is volts per meter). Does the orientation of the bone matter? Could you ask a butcher to cut a slice from a large beef bone?
Edit: Also what voltage are you using?
I tried with cooked bone, that tends to be what I have more of lying around :D
I don't recall the voltage I tried, but it was probably something in the range of 5-9v. I didn't try with a very thin slice, it was a few mm thick. Probably a thinner slice is the thing to try. That's a bit hard with bird bones (hollow), so maybe I'll have to cook something else. I don't have a microtome, so I'll have to cut some thin slices by trial and error.
I would hazard a bet that orientation matters. The studies that measured bone piezoelectricity seemed to suggest some orientations made more sense than others, but I don't recall what exactly. In any case, they had... very different applications in mind.
