Dielectric elastomers are electro-mechanically coupled transducers that display a nonlinear viscoelastic stress-strain relationship. Modeling and controlling such nonlinear materials and actuators are of great challenge. A spring roll dielectric elastomer actuator is a linear actuator composed of a spring and sheets of wrapped dielectric elastomers. Since its shape and actuation performance resemb...
