A piezo-electric type of assembly for effecting and interfacing relative motion between two surfaces. The assembly consisting of a first and a second transducer to be driven by electrical signals. Both transducers are coupled at one end to a low inertia member that is to make contact with a second surface. The first transducer controls this contact by moving the low inertial member relative to a high inertia member. The second transducer is coupled at the other end to a first surface. While the low inertia member is making contact with the second surface, activation of the second transducer causes relative motion between the first surface and the second surface due to frictional contact. The second transducer is reset while the first transducer causes momentary break of contact. The operation of this cycle has many applications.
