Abstract
A bending actuator device or sensor device for sensing bending comprises a stack of electroactive polymer units. The adjacent electroactive polymer units in the stack are slidable relatively to each other. This means that, for an actuator for example, an increased actuation force is enabled without requiring increased driving voltage, and it also avoids the problems of stress build up by allowing sliding between the units.
