Abstract
The present invention relates to dielectric actuators or sensors of the kind wherein electrostatic attraction between two electrodes located on an elastomeric body leads to a compression of the body in a first direction and a corresponding extension of the body in a second direction. The dielectric actuator/sensor structure comprises a first sheet of elastomeric material having at least one smooth surface and a second surface and a second sheet of elastomeric material having at least one smooth surface and a second surface. The sheets are laminated together with their second surfaces exposed, and there is provided a first electrode on the second surface of the first sheet and second electrode on the second surface of the second sheet.
