Abstract

Dielectric Elastomer Actuators (DEAs) are a kind of deformable capacitor that can undergo large voltage-induced deformations higher than 100% in area. Subject to an electrical field, the layer of the dielectric elastomer film reduces in thickness and expands in area. Large-strain, fast and efficient actuation properties are attractive for a wide range of possible applications, such as artificial muscles, tuneable optical devices and tactile displays. However, the performance of DEAs is currently constrained by their electrical breakdown strength. Therefore, studying dielectric breakdown behavior is a very significant consideration. In order to measure the electrical breakdown strength of dielectric elastomers, an experimental set-up has been built. This paper shows preliminary results of an ongoing programme of characterisation tests on the acrylic elastomer film VHB 4905 from 3M.
