Abstract

Electro-active actuators and methods of manufacturing such actuators are described having a longitudinally extended layer of electro-active material bent to form a non-straight, curved line or contour of uniform or non-uniform curvature, which line or contour having section with a mean radius of curvature to thickness ratio r/t close to 0.5. The layer is preferably monolithic with no buried electrode layer or layers, thus facilitating manufacture.
