<P>PROBLEM TO BE SOLVED: To provide electroactive polymers, transducers and devices that maintain pre-strain in one or more portions of the electroactive polymers. <P>SOLUTION: Electroactive polymers 60 may include a pre-strained portion 62 and a stiffened portion which is configured to maintain pre-strain in the pre-strained portion 62. One fabrication technique applies pre-strain to a partially cured electroactive polymer 60. The partially cured polymer 60 is then further cured to stiffen and maintain the pre-strain. In another fabrication technique, a support layer is coupled to the polymer 60 that maintains pre-strain in a portion of the electroactive polymer 60. Another embodiment cures a polymer precursor to maintain pre-strain in the electroactive polymer 60. <P>COPYRIGHT: (C)2013,JPO&INPIT |
