don't know about polymer material...
... but have experimented with nickel-titanium alloy wires that
react (i.e. "bend" -- expand and contract) when a current is applied
(anywhere from 50 to approx. 400 mA will work ok)...
they can be purchased in sample quantities, along with a booklet
describing how to use 'em --
-- from a company called:
mondo-tronics
2476 verna ct.
san leandro, CA 94577
1-800-374-5764
tons of lil' advertisments for this stuff (i.e. the mondo-tronics
sampler) can be found in the magazine rack electronics books (like
"radio electronics" magazine for example)...
... such magazines are a neat source for weird lil' companies sellin'
all kinds 'o bizarre "garage" variety components.
