Electroactive polymer actuated devices

Image Number 10 for United States Patent #7595580.

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.
