  • Patent number: 9835696
    Abstract: A magnetic field sensor includes first and second sensors for detecting first and second magnetic components according to first and second directions. Each sensor includes a flux concentrator including first and second magnetic parts, an air gap between the parts, and a magnetoresistive element in the air gap. Each magnetoresistive element includes a reference layer having a fixed magnetization direction, the fixed magnetization direction of the first and second sensors being substantially identical, and a sensitive layer having a variable magnetization direction, the variable magnetization direction of the first sensor when the first sensor is in a state of rest being substantially identical to the variable magnetization direction of the second sensor when the second sensor is in the state of rest. The air gaps of first and second sensor are oriented parallel to a direction XY which is, at ±15°, the bisector of the first and second directions.

  • Patent number: 9557392
    Abstract: Integrated magnetometer comprising a plurality of multilayer magnetoresistive sensors deposited on a surface, called the top surface, of a substantially planar substrate, characterized in that said top surface of the substrate has at least one cavity or protuberance provided with a plurality of inclined faces, and in that at least four said magnetoresistive sensors are placed on four said magnetoresistive sensors are placed on four said inclined faces, having different orientations and opposite one another in pairs, each sensor being sensitive to one component of an external magnetic field parallel to that face on which it is placed. Process for manufacturing such a magnetometer.

  • Patent number: 9304336
    Abstract: A magneto-optic surface includes a support; at least two moving elements; each of the moving elements including at least one anchoring point to the support and at least one moving part movable with respect to the support, the moving part including at least one magnetic part; the support and the moving elements being laid out in such a way that under the effect of an external magnetic field, at least one of the moving elements moves with respect to the support such that the optical properties of the magneto-optic surface are modified.

  • Patent number: 8686818
    Abstract: A microparticle includes an oblong flexible tail able to propel the microparticle in a solution along a trajectory using beats transverse to the trajectory, the tail including at least one magnetic element such that the magnetic element causes beats of the tail under the action of an external alternating magnetic field non-collinear with the trajectory and a head mechanically connected to a proximal end of the tail. The microparticle includes at least one layer of material formed from one piece and including the tail and the head, the dimensions and/or shape of the head being selected such that the beats of the proximal end of the tail are limited with respect to the beats of the distal end of the tail and such that the head does not perform a complete revolution around an axis parallel to the trajectory under the effect of the external alternating magnetic field.

  • Publication number: 20130052343
    Abstract: A method for manufacturing particles includes depositing on a substrate a layer of a first sacrificial material; depositing on the layer of the first sacrificial material a layer of a second sacrificial material that is different from the first sacrificial material; forming cavities in the layer of the second sacrificial material, the forming including pressing a structured mold against the layer of second sacrificial material; depositing a material for manufacturing the particles, the material covering the layer of the second material and at least partially filling the cavities; selectively removing the second sacrificial material from the first sacrificial material so as to obtain the particles formed by the material and arranged on the layer of the first sacrificial material; and eliminating the first sacrificial material to release the particles.
