Abstract:
1. A flat stacked-type conductive polymer actuator comprising: a first conductive polymer film, a plate-shaped first porous member, a second conductive polymer film, and a plate-shaped second porous member, which are stacked on one another, wherein each of the first porous member and the second porous member has an ionic solution injected thereinto so as to function also as an electrolyte retention layer, a first end portion of the first porous member and a first end portion of the second conductive polymer film that are opposed to each other are connected to each other, a first end portion of the first conductive polymer film and a first end portion of the second porous member that are opposed to each other are connected to each other with a spacer being interposed therebetween, a second end portion of the first porous member and a second end portion of the first conductive polymer film that are opposed to each other are connected to each other, a second end portion of the second conductive polymer film and a second end portion of the second porous member that are opposed to each other are connected to each other, and by applying an electric potential difference between the first conductive polymer film and the second conductive polymer film, one of the first conductive polymer film and the second conductive polymer film is expanded or contracted and the other conductive polymer film is contracted or expanded by an oxidation-reduction reaction, so that a driving force is externally outputted by displacements of the first porous member and the second porous member.
