Dielectric Elastomer Actuators

Dielectric Elastomer Actuators (DEA) can be manufactured in many different shapes, allowing for an exceptionally wide range of designs. The basic structure consists of an elastomer film (dielectric) covered on both sides with easily deformable electrode layers. When a voltage is applied between the electrode layers, the thickness of the soft elastomer film is compressed and its surface expands. This results in deformations of the order of 10 %. Dielectric Elastomer Actuators have a low weight and operate silently.

Silicone is usually chosen as the elastomer material, the mechanical properties of which can be varied over a wide range. An increase in the actuation force generated by the deformation of the material in the electric field is achieved by increasing the dielectric constant compared to pure silicone. Silicones filled with conductive particles such as carbon black, graphite or metals serve as electrode materials. The Center Smart Materials and Adaptive Systems already has extensive experience with all the above-mentioned materials.
