>"Lead zirconate titanate is an inorganic compound with the chemical formula Pb[ZrxTi1−x]O3 (0≤x≤1). Also called lead zirconium titanate, it is a ceramic perovskite material that shows a marked piezoelectric effect, meaning that the compound changes shape when an electric field is applied." Here's my curiousity: We've assumed thus far in Physics, that the piezoelectric effect causes materials that are piezoelectric in nature to change shape, to bend, when electricity is applied. But... What if that was not true... What if the piezoelectric material -- doesn't change shape at all, when electricity is applied? How would this be possible? What if, what really happens, is that the piezoelectric material retains its exact same shape -- but the space around it, containing it, is bent -- by the electricity? Sort of like a lensing effect caused by the electricity. First you look at the piezoelectric material one way, then you apply electricity, and it appears to bend out of shape (much in the same way a properly shaped mirror or lens could accomplish the same perceptual effect). But what might actually be happening is that the space around and in the object -- might be getting bent by the application of electricity to it... Yes, I know! Sounds like a crackpot theory, in fact, probably is a crackpot theory(!) <g> -- but perhaps this idea is worth exploring... (Note To Future Self: Investigate this idea further...)
