Abstract
Described herein are transducers and their 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 provides methods for fabricating electromechanical devices including one or more electroactive polymers.
Claims10
A polymer roll transducer comprising:
- an electroactive polymer roll having a plurality of layers of an electroactive polymer having an elastic modulus below 100 MPa in a rolled configuration;
- and
- an end cap to secure the electroactive polymer roll in its rolled configuration, wherein the electroactive polymer has an electrode having a non-uniform shape disposed thereon.
