Title: ACTUATOR DEVICE AND METHOD FOR OPERATING SAME
Abstract:
This actuator device is provided with: an actuator (1); and an alternating current power source (5) which can apply a high-frequency voltage to the actuator. The actuator is provided with: a flexible tube (2) formed from a polymer; an inner electrode (3); and an outer electrode (4). In a cross-section perpendicular to the longitudinal direction of the flexible tube, the inner electrode contacts at least a portion of the inner circumferential surface of the flexible tube. In this cross-section, the outer electrode covers a portion of the outer circumferential surface of the flexible tube. The alternating current power source applies, to the actuator, a high-frequency voltage having a frequency of at least 1 MHz during operation, and displaces, in the cross-section, the actuator in a direction from the inner electrode toward the outer electrode. In addition, the alternating current power source stops the application of the high-frequency voltage to the actuator and returns the actuator to the original position thereof.
