1. A method of fabricating a device comprising an electroactive polymer and multiple electrodes, the method comprising:
- mechanically stretching a polymer to form a pre-strained electroactive polymer, wherein the pre-strained electroactive polymer has an elastic modulus below 100 MPa;
fixing a first portion of the pre-strained electroactive polymer to a solid member;
forming a first electrode on a portion of a first surface of the pre-strained electroactive polymer; and
forming a second electrode on a portion of a second surface of the pre-strained electroactive polymer.

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.

12. A method of fabricating a device comprising an electroactive polymer and multiple electrodes, the method comprising:
-
mechanically stretching a polymer to form a pre-strained electroactive polymer, wherein the pre-strained electroactive polymer has an elastic modulus below 100 MPa; fixing a portion of the pre-strained electroactive polymer to a solid member; spraying an electrode solution onto a first surface of the electroactive polymer using a first mask that defines a pattern for a first electrode on the first surface of the electroactive polymer; and spraying the electrode solution onto a second surface of the electroactive polymer using a second mask that defines a pattern for a second electrode on the second surface of the electroactive polymer. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
