Electronic electro-active polymers (EEAPs) are dielectric materials that change their mechanical and electrical properties in response to electric stimulations. These materials have proved to be very promising materials in the development of actuators and sensors. In making actuators and sensors using EEAPs, a thin layer of polymer is placed between two compliant electrodes. In actuator mode, the layer is charged with a sufficient electric potential. In sensing mode, the capacitance across the layer is measured. In modeling and simulation of these materials, difficulties appear in dealing with the coupled electro-mechanical effect in which large deformation and the surrounding space must be taken into account. In this work, the behavior of EEAPs is modeled by the theory of nonlinear electro-elasticity and simulated using the coupled finite-boundary element method.
