Abstract

The present invention provides electroactive polymers (40), transducers and devices that maintain pre-strain in one or more portions (42) of an electroactive polymer (40). Electroactive polymers described herein may include a pre-strained portion (42) and a stiffened portion (44) configured to maintain pre-strain in the pre-strained portion (42). One partially cured polymer is then further cured to stiffen and maintain the pre-strain. In another fabrication technique, a support layer is coupled to the polymer that maintains pre-strain in a portion of an electroactive polymer. Another embodiment of the invention cures a polymer precursor to maintain pre- strain in an electroactive polymer.
