Abstract:
1. A device for converting between electrical and mechanical energy, the device comprising: a polymer roll transducer comprising a) an electroactive polymer including at least one active area and b) at least two electrodes in electrical communication with the active area wherein at least a portion of the electroactive polymer is wrapped upon itself to form a roll; at least one support member coupled to the polymer roll transducer for providing at least one of a force that strains at least a portion of the polymer, a force for controlling bending in the polymer roll transducer, and combinations thereof; and at least one mechanical linkage coupled to the polymer roll transducer for allowing a force or a moment generated in a first portion of the electroactive polymer to be communicated to a second portion of the electroactive polymer.
