Abstract
Medical devices or components thereof having electroactive polymer actuators embedded within at least a portion of the device of component thereof, and novel electroactive polymer actuators formed with a conductive substrate layer and an electroactive polymer layer, the electroactive polymer actuated upon application of a voltage to surrounding liquid electrolyte, the actuators may be embedded within an inert polymer matrix material, or within solid polyelectrolyte matrix material.
