摘要：

A conically shaped Dielectric Elastomer (DE) linear actuator is presented which is obtained by coupling a DE film with a compliant mechanism. The compliant mechanism is designed, by means of a pseudo-rigid-body model, to suitably modify the force generated by the elastomer film. The resulting actuator provides a nearly constant force along the entire actuator stroke when the DE film is activated and returns M an initial rest position when the DE film is deactivated. Experimental activity fully validates the proposed concept. Passible applications of this kind of actuator are Braille cells, light weight robots and haptic devices.
