<P>PROBLEM TO BE SOLVED: To provide an actuator and a micro pump which can be reduced in size and weight. <P>SOLUTION: The actuator 10 is used for the micro pump and has a tube shape. The actuator 10 is constituted of a plurality of layers from the inner peripheral surface toward the outer peripheral surface of the tube and has a first electrode layer 1, an electrolyte layer 4, a deformation layer 3 and a second electrode layer 2 from the inner peripheral surface side in order. In the actuator 10, the volume of the deformation layer 3 is expanded or contracted by an oxidation-reduction reaction and driving is performed so that the inside diameter of the tube is changed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
