Abstract

Planar electrohydraulic HASEL (hydraulically amplified, self-healing, electrostatic) actuators are soft actuators which display large linear strains and actuation stresses, as well as high specific energies and specific powers. We use the energy minimization approach to derive a nonlinear quasistatic model to describe the actuation behavior of planar HASEL actuators. In the model, we consider the large strains in the shell due to the Maxwell stress, large deflections of the actuator from the electrostatic zipping, and the hydraulic coupling due to the liquid. We apply the model to both linear planar and circular planar HASEL actuators and compare the results with experimental data
