  • Publication number: 20240034616
    Abstract: The invention relates to an electromechanical microsystem comprising an electromechanical transducer, a deformable membrane and a cavity hermetically containing a deformable medium, preserving a constant volume under the action of an external pressure change. The deformable membrane forms a wall of the cavity and has at least one free zone being deformed. The electromechanical transducer is configured, such that its movement is a function of said external pressure change, and conversely. The free zone engages with an external member, such that its deformation induces, or is induced by, a movement of the external member. The electromechanical microsystem is thus capable of moving the external member or of capturing a movement of this member.

  • Patent number: 11679974
    Abstract: A mechanical microsystem including a pair of elastically deformable elements, a mechanical hinge joining the deformable elements together, and at least two electroactive layers. The microsystem is configured such that, from a rest position wherein the deformable elements fall into a plane, a deformation of one of the deformable elements displacing it outside of the plane induces an electric current circulation in one of the two electroactive layers, and/or conversely. Each deformable element has a front face and a rear face opposite one another and substantially parallel to the plane. A first electroactive layer is arranged together with a first deformable element on its rear face, and a second electroactive layer, different from the first layer, is arranged with a second deformable element, different from the first element, on its front face.

  • Patent number: 11624874
    Abstract: A scanner is provided with a plurality of elementary scanners each able to scan a different surface by means of a light beam. Each elementary scanner comprises a beam, for example a vibrating beam, on or in which a phase-controlled array is formed, intended to extract, at a face of the beam, a light beam able to be emitted by a light source. At least one beam of one of the elementary scanners, referred to as the first scanner, has, at rest, a deflection different from that of the beams of the other elementary scanners. This arrangement enables the first scanner to scan a surface, referred to the first surface, different from that scanned by the other elementary scanners. The optical scanner according to the present invention makes it possible to cover a relatively large surface while keeping appreciable compactness.

  • Publication number: 20220380205
    Abstract: An electromechanical microsystem including an electromechanical transducer, a deformable diaphragm and a cavity hermetically containing a deformable medium keeping a constant volume under the action of an external pressure change. The deformable diaphragm forms a wall of the cavity and has at least one free area so as to be elastically deformed. The electromechanical transducer is configured so that its movement depends on the change in the external pressure, and vice versa. The free area cooperates with an external member so that its deformation induces, or is induced by, a movement of the external member. Thus, the electromechanical microsystem is adapted to displace the external member or to detect a movement of this member, the electromechanical microsystem includes at least one pin, configured to bear on a peripheral portion of the free area so that a deformation of the free rea causes an inclination of the pin.

  • Publication number: 20220380206
    Abstract: An electromechanical microsystem including an electromechanical transducer, a deformable diaphragm, a first cavity hermetically containing a deformable medium keeping a substantially constant volume under the action of an external pressure change and a second cavity. The deformable diaphragm forms a wall of the cavity and has at least one area freely deformable elastically. The free area also forms a wall of the second cavity. The electromechanical transducer is configured so that its movement depends on the external pressure change, and vice versa. A change in the external pressure in the first cavity induces a variation of the volume of the second cavity, or vice versa. Thus, the proposed electromechanical microsystem enables gripping of an object obstructing the opening of the second cavity and forms a microbarometer capable of converting at least one ambient pressure change into an electrical signal.

  • Publication number: 20220197013
    Abstract: The invention relates to an electromechanical microsystem 1 including at least two electromechanical transducers 11 a and 11 b, a deformable diaphragm 12 and a cavity 13 hermetically containing a deformable medium 14 maintaining a constant volume under the action of an external pressure change. The deformable diaphragm forms a cavity wall and has at least one elastically deformable free area 121. The electromechanical transducers are configured so that their movement is a function of the said external pressure change, and vice versa, and so that two of them have opposing movements relative to each other. The free area cooperates with an external member 2 so that its deformation causes, or is caused by, a movement of the external member. The electromechanical microsystem is thus able to move the external member and/or sense a movement of this member, alternately towards the inside or outside of the cavity.
