Patent ID: 7696669

Claim:
A bendable electrically conductive polymer actuator composed of a laminate wherein a first electrode, a solid electrolyte membrane, an electrically conductive polymer membrane, and a second electrode are laminated in this order, wherein: the solid electrolyte membrane is constituted with a mixture of an organic polymer and an ionic liquid; the organic polymer comprises at least one or more of a vinylidene fluoride/hexafluoropropylene copolymer [P(VDF/HFP)], polyvinylidene fluoride (PVDF), a perfluorosulfonic acid/PTFE copolymer, polymethyl methacrylate (PMMA), polyethylene oxide (PEO) and polyacrylonitrile (PAN); and the electrically conductive polymer membrane is constituted with a mixture of polyethylenedioxythiophene (PEDOT) and polystyrene sulfonic acid (PSS), and wherein the electrically conductive polymer contains polyethylene.
