Polymer actuator, the actuator device and method for fabricating the

The present invention provides a polymer actuator, comprising: a pair of facing portions facing each other; and a folded portion, the end portions of each pair of facing portions coupled to each other by the folded portion, wherein said a and the pairs of the folded portion from the inner portion is constituted by sequentially laminating an inner electrode layer, an electrolyte layer and an outer electrode layer. Therefore, a portion in the pair are respectively displaced to the displacement added to each other, and also due to the bending displacement is generated in the folded portion. As a result, a large displacement as a whole. Thus, to achieve the simplification of the structure, the displacement amount can be increased. The present invention further provides a polymer comprising the actuator means of the actuator, the method of manufacturing the actuator and a method of manufacturing the actuator device of said polymer.
