Energy analysis of a DEAP based cylindrical actuator coupled with a radial negative stiffness spring

Yves Perriard, Yoan René Cyrille Civet, Jonathan André Jean-Marie Chavanne

The main problem to obtain considerable deformation with dielectric electro-active polymer based technology is the electrical breakdown. A simple solution consists in pre-stretching the elastomer before activating it which cancels the snap-through effect a ...
