Electromechanical microsystem

An electromechanical microsystem comprising:

• at least two electromechanical transducers each comprising a portion movable between a balance position, off-load, and an out-of-balance position, under load,
• a first deformable diaphragm,
• a deformable cavity formed by walls, the walls being configured to hermetically contain a deformable medium capable of keeping a substantially constant volume under the action of a change in the external pressure,
• wherein at least one portion of the first deformable diaphragm forms at least one portion of a first wall selected amongst said walls of the cavity, wherein the movable portion of each electromechanical transducer is configured so that its movement depends on said change in the external pressure and vice versa, and wherein said at least one portion of the first deformable diaphragm has at least one area freely deformable as a function of said change in the external pressure, the electromechanical microsystem being further such that:
• a first electromechanical transducer forms a portion of said first wall of the cavity, and
• a second electromechanical transducer forms at least one portion of the wall opposite to said first wall of the cavity, and,
• wherein the free area of each deformable diaphragm is configured to cooperate with at least one external member via at least one pin fastened on said free area.
