Abstract

In this paper, we establish the thermodynamic theory of dielectric elastomer under electromechanical coupling field, different effects are considered, including polarization saturation, strain hardening and stress softening. The instability and dynamic performance of dielectric elastomer is also studied. At last, the devices and application of dielectric are introduced, such as soft robot, energy harvester, gripper.
