Polymer with piezoelectric effect

Polymer with piezoelectric effect

(OP)
I am trying to find a polymer that can be expanded against pressure, as a result of piezoelectric or other mechanism;  which can be manipulated and is expandable after applying some pressure between the fingers.

RE: Polymer with piezoelectric effect

PVDF = poly vinylidene fluoride.  This from wikipedia.

PVC also supposedly.

I doubt either is as efficient as some of the ceramic materials.  None of the materials will expand very much without hazardous levels of voltage for an object being held.
