Abstract

Electro-active polymers (EAPs) have the ability to undergo large deformations upon the stimulation by an electric field. They offer new design possibilities in a variety of applications, such as simple soft and flexible actuators, stretchable sensors, and energy harvesters. In the subclass of dielec...
