A dielectric elastomer planar actuator consists of a polymeric film included between two compliant electrodes. A voltage difference applied between the electrodes generates an electrostatic pressure which compresses the film thickness and expands its surface [1, 2]. The high performances [3] and low costs of dielectric elastomers, belonging to the class of electroactive polymers, suggest their advantageous use for the actuation of small scale devices [1]. The following figures present some possible simple applications of such actuators.
