ACTUATOR
An actuator is configured such that a first film body and a second film body are stacked on each other. The first film body includes a first dielectric elastomer film and a first electrode layer provided on a surface of the first dielectric elastomer film. The second film body includes a second dielectric elastomer film and a second electrode layer provided on a surface of the second dielectric elastomer film. The electrode layer included in at least one of the first film body and the second film body includes a plurality of linear electrodes extending in a first direction and provided at intervals in a second direction that is orthogonal to the first direction.
1 . An actuator comprising:
a first film body including a first dielectric elastomer film and a first electrode layer provided on a surface of the first dielectric elastomer film; and
a second film body including a second dielectric elastomer film and a second electrode layer provided on a surface of the second dielectric elastomer film, wherein:
the actuator is configured such that the first film body and the second film body are stacked on each other; and
the electrode layer included in at least one of the first film body and the second film body includes a plurality of linear electrodes extending in a first direction and provided at intervals in a second direction that is orthogonal to the first direction.
2 . The actuator according to claim 1 , wherein the first film body and the second film body are rolled while the first film body and the second film body are stacked on each other.
3 . The actuator according to claim 2 , wherein the first film body and the second film body are rolled such that the first direction coincides with a direction in which the first film body and the second film body are rolled while the first film body and the second film body are stacked on each other.
4 . The actuator according to claim 1 , wherein the electrode layer includes the plurality of linear electrodes extending in the first direction, a first connection electrode connecting a first end of one of the linear electrodes and a first end of another one of the linear electrodes that is adjacent to the one of the linear electrodes on one side, and a second connection electrode connecting a second end of the one of the linear electrodes and a second end of yet another one of the linear electrodes that is adjacent to the one of the linear electrodes on the other side.
