Abstract: In order to stably operate an actuator device in repeated operations with suppression of an increase in a resistance value of a heating wire, the actuator band according to the present disclosure comprises a plurality of actuator wires and a plurality of heating wires. Each of the plurality of the actuator wires is formed of a fiber which consists of a polymer. The fiber is twisted along the long axis thereof and folded so as to have a cylindrical coil shape. Each of the plurality of the actuator wires is contracted by heat and restored by release of the heat. A braided fabric is formed with the plurality of the actuator wires arranged in a planer shape and the plurality of the heating wires. A first end of each of the plurality of heating wires is connected to a first end of each of the plurality of the actuator wires. A second end of each of the plurality of the heating wires is connected to a second end of each of the plurality of the actuator wires.

Abstract: The present disclosure provides an actuator device having a large ratio of contraction ratio to initial tension. The actuator device according to the present disclosure comprises an actuator band and a control device. The actuator band is formed by braiding, knitting, or weaving a plurality of actuator single wires. The plurality of the actuator single wires each comprise an actuator wire and a mesh-shaped heating element which covers a side surface of the actuator wire. The actuator wire is formed of a polymer fiber. The fiber is twisted around the long axis thereof and folded so as to have a cylindrical coil shape. The control device is configured to supply electric power for heating the mesh-shaped heating element. The actuator band is heated to be contracted along the longitudinal direction thereof.
