Electromechanical system comprising capacitive measurement or actuation means

An electromechanical system comprising:

• a frame;
• an element movable relative to the frame, in contact with a first zone;
• a capacitive measurement or actuation system comprising an electrode movable relative to the frame, located in a second zone which is sealingly insulated from the first zone, and at least one electrode fixed relative to the frame, forming a counter-electrode, the movable electrode comprising a membrane and a membrane rigidifying structure;
• a transmission device for transmitting movement between the movable element and the movable electrode, the transmission device being rotatably movable relative to the frame by a plurality of pivot hinges;
• and
• an elastic device connected to the movable electrode and configured to generate an elastic force which opposes movement of the movable electrode;
• wherein the membrane rigidifying structure of the movable electrode is secured to the transmission device and anchored to the transmission device at at least one part of the pivot hinges.
