Abstract
An actuator or sensor device comprises an electroactive polymer (EAP) arrangement which extends between fixed opposite ends. The electroactive polymer arrangement comprises a passive carrier layer and an active electroactive polymer layer, wherein at or adjacent the ends, the passive carrier layer and the active EAP layer are mounted with one over the other in a first order, and at a middle area between the ends, the carrier layer and the active EAP layer are mounted in an opposite order. This enables internal stresses and moments within the electroactive polymer arrangement to be used more effectively to contribute to displacement or actuation force.
