Multilayer Dielectric Elastomers for Fast, Programmable Actuation without Prestretch

A novel method for the fabrication of dielectric elastomer actuators (DEAs) combines acrylic polymers and single wall carbon nanotube network electrodes. DEAs made using this technique do not require prestretching, have extremely thin electrodes, and can be actuated at low voltage. The method is applied to create a multimorph device with nine actuation modes based on just four inputs.
