ABSTRACT:
An ion conducting actuator includes a substrate which is made of a polymer material, and facing electrodes for generating an electric field. In the ion conducting actuator, a shape of the substrate is deformed to a desired shape by distributing unevenly ions and/or polar molecules in the substrate by applying a voltage between the facing electrodes. A deformation state is formed by a shape-maintained time t2for which the shape of the substrate is maintained substantially, and a deformation-start time t1which is before the shape-maintained time t2, and during which, the shape of the substrate is deformed from an arbitrary shape to a desired shape. A drive voltage V applied to the ion conducting actuator differs during the shape-maintained time t2, and during the deformation-start time t1.
