Professor Luis Dorfmann recently published a review article in Proceedings of the Royal Society of London A on the mechanical–electrical coupling in elastomeric materials that can undergo large deformations induced by electric fields.

With Professor Ray Ogden from the University of Glasgow, Dorfmann reviewed the key experiments and mathematical and modelling aspects of that coupling, which has enormous potential for diverse applications, including actuators, sensors, artificial muscles, soft robots, noise suppression, and energy generation.

The paper also provided a review of the history of developments in nonlinear theory and a review of modern electroelastic theory. Following that summary, Dorfmann and Ogden applied modern electroelastic theory to two simple geometries that are representative of the design of prototype actuators. Ultimately they recommended further study on microscopic and multiscale approaches, and the gathering of more experimental data in order to allow the use of more refined models.
