ABSTRACT:
A shape memory material activated device of the present invention uses a shape memory material activator to create a path through a shell wall of the device. The path through the shell wall may release a substance contained in the shell or allow a substance to enter the shell. The path may be created by fracturing, puncturing, exploding, imploding, peeling, tearing, stretching, separating, debonding or otherwise opening the shell. The devices according to the present invention may be used as temperature sensors or warning devices, drug delivery devices, and the like.
