Abstract: A dielectric elastomer transducer A1 includes a dielectric elastomer layer 2, a pair of electrode layers 3A, 3B sandwiching the dielectric elastomer layer 2, and a support 1 that supports the dielectric elastomer layer 2. The dielectric elastomer layer 2 includes a movable region 21 separated from the support 1 and a fixed region 22 supported by the support 1. A pair of conduction paths 8A, 8B are established that are configured to conduct electricity to the electrode layers 3A, 3B via power cables 4A, 4B and power supply points 6A, 6B at which core wires 41A, 41B of the power cables 4A, 4B are electrically connected, respectively. The power supply points 6A, 6B are separated from the movable region 21 of the dielectric elastomer layer 2. This arrangement improves the durability of the dielectric elastomer transducer.

Abstract: A dielectric elastomer motor includes an artificial muscle and a conversion mechanism cooperating with the artificial muscle. The artificial muscle includes a dielectric elastomer film or layer having a first surface and a second surface opposite to the first surface. First and second electrodes are attached to the first surface and the second surface of the dielectric elastomer film, respectively. First and second bases are attached to the dielectric elastomer so as to be spaced apart from each other. The first base and the second base are capable of reciprocation relative to each other upon change in size of the dielectric elastomer. The conversion mechanism converts the reciprocation of the bases to pivotal or rotational movement. The dielectric elastomer receives voltage application with a predetermined timing via the first and the second electrodes.
