    Abstract: A micro-electromechanical (MEM) resonator is described that includes a substrate, a microbridge beam structure coupled to the substrate and at least one electrode disposed adjacent to the microbridge beam structure to induce vibration of the beam. The microbridge beam structure includes support sections and a beam formed between the support sections. The center region of the beam has a mass that is less than the mass of regions of the beam adjacent to the support sections.

    Abstract: The invention relates to a microsystem comprising a deformable bridge (1), the ends (2) of which are connected to a substrate (3). According to the invention, at least one actuation electrode (6), which is solidly connected to the bridge (1), is disposed between the centre (C) of the bridge and one of the ends (2) next to a counter electrode (7) which is solidly connected to the substrate (3). The electrodes (6) are intended to deform the deformable bridge (1) such that a lower face of the bridge (1) comes into contact with a contact element (4) formed on the substrate (3). The actuation electrode (6) comprises, transversely to the bridge (1), a central zone (8) which is disposed on the bridge (1) and at least one projecting, flexible lateral flange (9). The lateral flange (9) can be connected to the central zone (8) by means of a narrower linking zone (10) which is disposed on the side of the flange (9) closest to the centre (C) of the bridge. Moreover, each actuation electrode (6) can comprise a pair of lateral flanges (9) which are disposed respectively on either side of the corresponding central zone (8).

    Abstract: The present invention relates to MEMS device that comprises a first electrode, and a second electrode suspended with a distance to the first electrode with the aid of a suspension structure. The MEMS device further comprises at least one deformation electrode. The second electrode or the suspension structure or both are plastically deformable upon application of an electrostatic deformation force via the deformation electrode. This way, variations in the off- state position of the second electrode that occur during fabrication of different devices or during operation of a single device can be eliminated.

    Abstract: The invention relates to a micromechanical device comprising a mobile beam (1), said beam being attached by the two ends (2) thereof to a rigid frame (3) provided with two arms (4) each having two ends (5). The ends (5) of an arm (4) are respectively fixed to the two ends (2) of the mobile beam (1). Each arm (4) has a central part (6) arranged between the two ends (5) of the corresponding arm (4). A rear face of the central part (6) of each arm (4) is attached to a base support (10). The frame (3) comprises at least one stressed element (11) for adjusting the stressed state of the beam. The stressed element (11) can be centred between the front face and the rear face of the corresponding arm (4). The frame (3) can comprise pairs of front and rear stressed elements (11) which are respectively arranged on the front face and the rear face of the arms (4) in such a way that they face each other.
