摘要： An actuator includes an electrolytic layer, a first electrode layer, and a second electrode layer. The electrolytic layer includes a polymer and an ionic liquid included in the polymer. When a voltage that makes the first electrode layer a positive side is applied, the actuator deforms to be in a drive state, thereby driving a protruding member. In a period other than a drive period in which the protruding member is driven, a reverse voltage that makes the first electrode layer a negative side is applied, thereby rectifying the tendency of the actuator to bow or the like.

摘要： Tubular linear piezoelectric motor (100, 300), and a method for exciting a tubular piezoelectric resonator (101, 301) used in such motor. The motor is comprised of a resonator (101, 301) formed of a cylindrical tube. The tube has length nL comprised of a piezoelectric material, where L is some length, and n is an even numbered integer, greater than zero. The piezoelectric material of the cylindrical tube is polarized in a radial direction, perpendicular at each point to the interior and exterior surface of the cylindrical tube. The resonator is excited with one signal having a single exciter frequency applied across an inner electrode (102, 302) and one or more first outer electrodes (103, 103a, 103b). The single exciter frequency is selected to move a contact site of one or more annular protrusions along an elliptical path when the resonator is excited. The resonator is disposed within an outer tube (106) and configured so that excitation of the resonator using the first outer electrode(s) produces linear displacement as between the outer tube and the resonator in a first direction. Excitation of a second outer electrode (104, 104a, 104b) produces the linear displacement in a second direction opposite to the first direction.
