Abstract
Two conductive polymer films, one of which swells and the other of which shrinks by an oxidation-reduction reaction, are connected to a link mechanism for reciprocally converting shrinkage-directional displacements of one film to swell-directional displacements of the other film, so that driving force in the expansion direction of one conductive polymer film can be generated by driving force in contraction direction of the other conductive polymer film.
