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.

Effect of Prestrain on the Actuation Characteristics of Dielectric Elastomers [PDF]
Polymers, 2020 Dielectric elastomers (DEs) represent a class of electroactive polymers that deform due to electrostatic attraction between oppositely charged electrodes under a varying electric field. Over the last couple of decades, DEs have garnered considerable attention due to their much-coveted actuation properties.
