発明の名称 (英語) Actuator element and production method therefor
発明の概要(英語) (US7315106)
An actuator element which functions stably in air and in vacuo, and can be driven at low voltages is described.
A actuator element which includes at least two electrode layers, each of which is mutually insulated and comprises a gel composition comprising carbon nanotubes, an ionic liquid and a polymer, are formed on the surface of ion-conductive layer comprising a gel composition comprising an ionic liquid and a polymer, so that the actuator element is capable of being flexed or deformed by creating a potential difference between the electrode layers; and an actuator element wherein at least two electrode layers, each of which is mutually insulated, are formed on the surface of ion-conductive layer, conductive layer is formed on the surface of each electrode layer, and the actuator element is capable of being flexed or deformed by creating a potential difference between the conductive layers.
