1. An electroactive polymer transducer driven camera comprising:
- a frame, a stable interface positioned centrally with respect to the frame, and electroactive polymer material stretched between the frame and the stable interface to form a diaphragm;
a lens unit positioned adjacent the stable interface;
wherein the motion of the diaphragm upon application of voltage changes the position of the lens unit to adjust the focus of the camera.

Abstract
Devices employing electroactive polymer actuators are disclosed. The devices include pumps, valves, cameras (where electroactive polymer actuators control either one or both of zoom and focus), vibrators (for inclusion in cell phones, game console controls, etc.) and audio speakers. These devices advantageously incorporate the actuator configurations descried. The devices generally incorporate a diaphragm-type actuation having a central section of material that is less flexible than adjacent material.
