Patent US6543110 - Electroactive polymer fabrication - Google Patents
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...http://www.google.com/patents/US6543110?utm_source=gb-gplus-sharePatent US6543110 - Electroactive polymer fabrication

US 6543110 B1
1. A method of fabricating a transducer comprising a pre-strained polymer and one or more electrodes, the method comprising:
pre-straining a first portion of a polymer to form the pre-strained polymer, wherein the polymer has an elastic modulus below 100 MPa;
fixing a second portion of the pre-strained polymer to a solid member; and
forming the one or more electrodes on the pre-strained polymer.
2. The method of claim 1 wherein the pre-strained polymer is elastically pre-strained.
(a) pre-straining a first polymer to form a first pre-strained polymer;
(b) forming one or more electrodes on the first pre-strained polymer;
(c) pre-straining a second polymer to form a second pre-strained polymer;
(d) forming one or more electrodes on the second pre-strained polymer; and
(e) coupling the first pre-strained polymer to the second pre-strained polymer.
17. The method of claim 16 wherein pre-straining comprises stretching the polymer and fixing it to a solid member.
