Abstract
An electro-mechanical wave device which may be used for movement of a mechanical member, e.g. by friction, a motor comprising one or more wave devices, and a method of providing the electro-mechanical wave device. The electro-mechanical wave device comprises a substrate comprising a plurality of conductors, and a plurality of actuators positioned on the substrate for generation of mechanical waves along a predetermined propagation path, each of the actuators being connected to a respective set of the conductors of the substrate for reception of an excitation signal transmitted by the set of conductors.
