A dielectric elastomer driving mechanism includes a driver, a follower, and a power transmitter. The driver includes a dielectric elastomer driving element made up of a dielectric elastomer layer and two electrode layers sandwiching the dielectric elastomer layer. The driver also includes a tension maintaining element maintaining, in a no-voltage state, the dielectric elastomer driving element in a state in which tension occurs, and includes an output portion capable of moving along with the expanding or contracting of the dielectric elastomer driving element. The follower includes a following element actuating in accordance with a driving force inputted. The power transmitter is connected to the output portion of the driver for transmitting a driving force of the driver to the follower.

Dielectric elastomer driving mechanism

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.
