A dielectric elastomer is capable of largevoltage-induced deformation, particularly when the voltage is applied on theverge of snap-through instability. Thispaper describes a model to show that the snap-through instability is markedlyaffected by both the extension limit of polymer chains and the polarizationsaturation of dipoles. The model mayguide the search for high-performance dielectric elastomer transducers.
