Electroactive polymers (EAPs) are polymers that respond to electrical stimulation with a significant shape or size change. Ideally these polymers are fabricated as flexible and compliant (stretchable) electrodes. A primary use of these materials is as artificial muscles.
In responding to an electric stimulation EAP materials experience strain and can be used as actuators. Dielectric actuators are one type of such actuator and are known to expand in area up to 300 percent when a voltage is applied to compliant electrodes on each face of an elastomeric film. Thus the electrodes should be just as, if not more, compliant than the elastomer film in dielectric actuators.
Researchers at the University of Maryland have developed a process for producing solid, highly complaint electrodes that can be cured with UV radiation or by a curing agent. More importantly these electrodes can be fabricated on a micro-scale, within many orders of steps less than the prior art at a fraction of the cost.
