When bent out of shape, can be -------- above a certain temperature it will return to it’s ----------- ------------.
It is normally an ----------------- (does not conduct electricity) but if pressure is applied it becomes a ---------------- (allows electricity to flow)

Biometrics
Polymorph
The material can “--------------” two distinct shapes, a ------ temperature shape and a -----temperature shape.
It is a -------- material yet becomes easily ------------ at 62°C.
