Paper Abstract

In this paper we present a dielectric elastomer actuator, which has the ability to sense the force acting on it without any additional sensing device. Basic physical behaviors of the dielectric elastomer are experimentally investigated and it is noted that the impedance of the dielectric elastomer varies depending on external forces acting on it. Based on that concept, we propose the principle of a self-sensing actuator according to experimental result. In addition, a multi-stacked actuator with self-sensing capability is realized to validate its feasibility.
