Patent ID: 7911115

Claim:
A transducer for converting between electrical energy and mechanical energy, the transducer comprising: a first active area having at least two first active area electrodes and a first portion of an electroactive polymer arranged in a manner which causes the first portion to deflect in response to a change in electric field provided by the at least two first active area electrodes and/or arranged in a manner which causes a change in electric field in response to deflection of the first portion; and a second active area having at least two second active area electrodes and a second portion of the electroactive polymer arranged in a manner which causes the second portion to deflect in response to a change in electric field provided by the at least two second active area electrodes and/or arranged in a manner which causes a change in electric field in response to deflection of the second portion, wherein the electroactive polymer has an elastic modulus below 100 MPa.
