Title: MEMBRANE ACTUATOR
Abstract:
The invention relates to a membrane actuator comprising a flexible membrane (2; 22; 42) and an actuator device (3, 4; 23; 24; 43, 44, 55) designed to introduce moving forces into part of the membrane (2; 22; 42) in order to locally deform the membrane (2; 22; 42). According to the invention, the actuator device (3, 4; 23, 24; 43, 44, 55) comprises at least one superconductor (3; 23; 43) and at least one magnet arrangement (14; 24; 44, 55), the magnetic interaction of which with the at least one superconductor (3; 23; 43) determines the moving forces acting on the membrane (2; 22; 42).
