What is an Electroactive Polymer?
• Electroactive polymers (EAPs) convert electrical energy to mechanical work and vice versa

How energy harvest using electroactive polymer
• If a low voltage charge is placed on a stretched elastomer prior to contraction and when the film is allowed to contract then electrical energy is generated.
• When the film is allowed to contract then elastic stress in the film work against the electrical field pressure,thus increasing electrical energy.
