Abstract: An MEMS has a substrate and a cavity arranged in the substrate. A movable element is arranged in the cavity, configured to interact with a fluid arranged in the cavity, wherein a movement of the fluid and a movement of the movable element are causally related. A first opening which connects the cavity to an environment of the substrate causes a first phase offset of a first periodic oscillation which is causally related to the movement of the movable element when passing through the first opening. A second opening which connects the cavity to the environment of the substrate causes a second phase offset, different from the first phase offset, of a second periodic oscillation which is causally related to the movement of the movable element when passing through the second opening.
