Abstract
A polyurethane elastomer actuator comprising a polyurethane elastomer 1 capable of deforming due to the orientation by an electric field, wherein the shrinkage displacement occurring at the time of the application of an electric field is transformed into other displacement. This polyurethane elastomer actuator does not require electrolyte and high voltage. Since it is not accompanied by chemical reactions and heat generation, its durability hardly deteriorates. This actuator deforms largely during driving.
