Definitions

  • the present invention relates to a conductive polymer actuator element made of polypyrrole.
  • An actuator using a conductive polymer can reduce the weight of the entire device incorporated because of its light weight, and can be used not only as a small drive device such as a micromachine but also as a large drive device. In particular, it is expected to be used for applications such as artificial muscles, robot arms, prosthetic hand actuators, and pumps.
  • a conductive polymer typified by polypyrrole not only has conductivity but also can incorporate ions as a dopant, and can be repeatedly doped and dedoped by applying a voltage. Therefore, the conductive polymer can exhibit electrolytic expansion and contraction, which is a phenomenon that expands or contracts due to electrochemical redox. This electrolytic expansion and contraction of the conductive polymer can be used as a drive for the actuator element.
