Dielectric elastomers are a variety of electroactive polymers, which are actuation materials that change size and shape in response to an electrical stimulation.

Abstract
Dielectric elastomers are a variety of electroactive polymers, which are actuation materials that change size and shape in response to an electrical stimulation. Dielectric elastomer actuators offer high strains, high energy output, lightweight, silent operation and low cost. They are being studied for many applications such as artificial muscles, robotic systems and haptic displays. This paper introduces the ongoing research at Queen Mary University of London on a novel approach to create a colour changing device using dielectric elastomer actuators. The idea relies on a DEA membrane with different colour spots covered by a mask with holes. With DEA in action, the colour spots move and due to the presence of the mask the colour displayed can change
