energy harvesting using electroactive polymer
DESCRIPTION
The use of polymers with electroactive response has only revealed in this decade with the introduction of EAP materials, having significant deformation levels. This emerging research has the potential to be a substitute to traditional, old solutions using piezoelectricity.TRANSCRIPT

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.
