This invention relates to an actuator or motor comprising an electromechanical material which alters its shape under the influence of an electrical voltage. Said actuator comprises at least a monolitic module (1,2) with electrodes integrated in said electromechanical material and in that the force or displacement due to the applied voltages is transferred, to the point to be actuated or moved by the shape change of the material, using at least two independent contact points. The invention also relates to a method for fabricating said actuator or motor.

[ What is claimed is:] [1.] An actuator or motor having electromechanical material which alters its shape under the influence of an electric field, whereby motion relative a body is created by non-resonant repetition of small steps, said actuator or motor comprising at least one monolithic module with electrodes integrated in said electromechanical material, said monolithic module being a sintered block and having at least one passive part and at least two active elements, one independent contact point at each active element being provided against said body, which contact points are positionable independently of each other in at least two independent directions relative to said passive part of said monolithic module, whereby said monolithic module by itself or in combination with others is used for creating said motion.
