Abstract
Provided is a gel actuator having generation force comparable to biological muscle at a low voltage, that can be used in various applications as an actuator element. A gel actuator (10) comprises a unit structure composed of a gel layer (14) containing a dielectric polymer material, and an anode (12) and a cathode (16) which sandwich the gel layer (14) in a thickness direction thereof, and a face of the anode (12) facing the gel layer formed into a concave-convex face, a convex part of the concave-convex face touching the gel layer (14), and a concave part thereof being into a gap.
Claims6
A gel actuator comprising:
- a unit structure composed of a gel layer containing a dielectric polymer material, and an anode and a cathode which sandwich the gel layer in a thickness direction thereof,
- and in the unit structure, one face of the anode facing the gel layer being formed into a one-side concave-convex face, convex parts of the one-side concave-convex face touching the gel layer, and concave parts of the one-side concave-convex face being formed into a gap into which the gel layer deforming by application of voltage between the anode and the cathode is entered,
- in the unit structure, an other face of the anode being formed into an other-side concave-convex face having other convex parts and other concave parts,
- wherein the anode is formed into a wave shape where the convex parts and the concave parts are alternately continuous in parallel, and
- wherein the convex parts and the concave parts on the one face of the anode respectively correspond to the other concave parts and the other convex parts on the other face thereof so that the gel actuator contracts in the thickness direction.
