Abstract
Described are methods for manufacturing and using an electromechanical soft actuator including a dielectric liquid crystal elastomer. A method for manufacturing the electromechanical soft actuator including the dielectric liquid elastomer may include the steps of fabricating a loosely cross-linked polydomain liquid crystal elastomer, pre-stretching the loosely cross-linked polydomain liquid crystal elastomer on a frame, cross-linking elements of the loosely cross-linked polydomain liquid crystal elastomer to form the dielectric liquid crystal elastomer and removing the frame from the dielectric liquid crystal elastomer. The disclosed electromechanical soft actuator including the dielectric liquid crystal elastomer can be used in transducer for converting electrical energy to mechanical energy. The transducer may include at least two electrodes, and the dielectric liquid crystal elastomer, which has a first position that is deflected to a second position in response to a change in an electric field provided by the at least two electrodes.
