Abstract
Pre-strained electroactive polymers are described that improve conversion from electrical to mechanical energy. When a voltage is applied to electrodes contacting a pre-strained polymer, the polymer deflects. This deflection may be used to do mechanical work. The pre-strain improves the mechanical response of an electroactive polymer. Also described herein are actuators that include an electroactive polymer and mechanical coupling to convert deflection of the polymer into mechanical work. Further described are compliant electrodes that conform to the shape of a polymer. Methods for fabricating electromechanical devices including one or more electroactive polymers are also described.
