**6.2. Electroactive polymer (EAP)**

Electroactive Polymer (EAP) is a polymer that exhibits a change in size or shape when stimulated by an electric field. The field generates coulomb attractive forces on the electrodes that apply compressive forces on the dielectric causing the change in size or shape. There are three primary types of EAP: Ionic, Piezoelectric and Dielectric. EAP can be used to create a variety of devices including sensors, actuators, and energy harvesting devices. Inclusion of EAP into composites laminate sandwich panels may have potential for a few excellent features such as vibratory deicing or wing warping.
