Abstract
A difference is arisen in the electric potential of the electrode layer between a fixed end portion and a displacement end portion of an actuator. The electrode layer includes a bundle of polymer fibers containing a conductive material. Longitudinal directions of the polymer fibers are arranged parallel to a direction from the fixed portion to the displacement end portion of the actuator.
Claims5
An actuator comprising:
- a pair of electrode layers;
- an electrolyte layer arranged between the pair of electrode layers, the electrolyte layer containing an electrolyte;
- and
- terminals in contact with the pair of electrode layers, the terminals being configured to apply a voltage between the electrode layers,
- wherein at least one of the pair of electrode layers includes a plurality of linear electrodes in contact with the electrolyte layer, longitudinal directions of the linear electrodes being arranged parallel to a direction from a terminal portion where the at least one of the electrode layers is in contact with a corresponding one of the terminals toward an end portion of the at least one of the electrode layers, and the end portion being remote from the terminal portion, and
- wherein the application of a voltage to the terminals allows ions in the electrolyte layer to be transferred, thereby displacing the end portion.
