Structure Design and Application of Dielectric Elastomer Actuator

As a new type of electroactive polymer, dielectric elastomer can be deformed when excited by an electric field, and can be restored to its original state when the electric field is cancelled. It has the characteristic of converting electrical energy directly into mechanical energy. By designing them as actuators with different configurations, it is possible to increase the deformability and meet different application requirements. In this paper, the actuation mechanism of dielectric elastomer actuators is introduced, and it is clarified that they are linear actuators capable of generating motion in a straight line manner. On this basis, actuators of different configurations can be designed. Dielectric elastomer actuators with different structure designs are summarized, and their performance characteristics, processing technology and potential applications are discussed.
