Abstract:
1. A polymer actuator, which is a plane thin-type polymer actuator, comprising: a conductive active member layer that is compatibly used as an electrode or has an electrode separately installed, and serves as a first electrode layer; a second electrode layer that is made face to face with the first electrode layer; a first electrolytic layer at least made in contact with the active member layer and sealed between the active member layer and the second electrode layer, the first electrolytic layer being a solid-state electrolyte having an elastic modulus of 3 kN/m a holding member for maintaining a thickness between the active member layer and the second electrode layer, wherein by applying an electric field between the two electrode layers, at least one type of ions selected from anions and cations are allowed to enter or leave the active member layer through the first electrolytic layer so as to expand or contract the active member layer.
