Heat efficient micromotor

摘要

An electromechanical actuator comprises at least two actuating portions of electromechanically active material extending by a generally elongated shape from a back portion. The actuating portions are bimorphs, attached by a first end to a first side of the back portion and positioned parallel to each other one after the other in a first direction. The bimorphs are arranged to provide movements of the second end along the first direction and along the extension of the actuating portion, thereby being able to move relative a body in the first direction. The actuating portions have generally flat internal electrode layers arranged inside the electromechanically active material directed substantially perpendicular to the first direction. The internal electrode layers extend continuously through the actuating portions and into the back portion.
