Actuator

摘要

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.

主权项

1. 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, the plurality of linear electrodes being closely arranged so that parts of the plurality of linear electrodes are in contact with each other, and wherein the application of a voltage to the terminals allows ions in the electrolyte layer to be transferred, thereby displacing the end portion.
