Abstract: Electroactive polymers that are pre-strained to improve conversion from electrical to mechanical energy are disclosed. 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. Furthermore, actuators including an electroactive polymer and mechanical coupling to convert deflection of the polymer into mechanical work are disclosed. Compliant electrodes that conform to the shape of a polymer are also disclosed. Methods for fabricating electromechanical devices including one or more electroactive polymers are provided.

Abstract: The present invention relates to transducers, their use and fabrication. The transducers convert between mechanical and electrical energy. Some transducers of the present invention include a pre-strained polymer. The pre-strain improves the conversion between electrical and mechanical energy. The present invention also relates to devices including an electroactive polymer to convert between electrical and mechanical energy. The present invention further relates to compliant electrodes that conform to the shape of a polymer included in a transducer. The present invention provides methods for fabricating electromechanical devices including one or more electroactive polymers.
