Abstract:
1. An electromechanical microsystem comprising: a base comprising a substrate and a substrate electrode fixed to the substrate, a mobile beam suspended above the substrate, a voltage generator, connected by a first terminal to the beam, and by a second terminal to the substrate electrode, adapted to generate a difference in potential between the beam and the substrate electrode, and at least one mechanical stop connected to the beam and adapted to come into contact with the base during application of a difference in potential between the beam and the substrate electrode defining an air-filled cavity between the beam and the substrate electrode, wherein said electromechanical microsystem also comprises an element for blocking electrical charges arranged on the substrate, opposite the at least one mechanical stop, and connected electrically to the beam, wherein said element for blocking electrical charges is constituted by a layer of resistive material having an electrical resistivity between 100 MOhms·square and 10 kOhms·square.
