Actuation response of polyacrylate dielectric elastomers [PDF]

SPIE Proceedings, 2001
Polyacrylate dielectric elastomers have yielded extremely large strain and elastic energy density suggesting that they are useful for many actuator applications. A thorough understanding of the physics underlying the mechanism of the observed response to an electric field can help develop improved actuators.
