  • 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.
