  • Variable-response magnetic radiofrequency device
    Patent number: 8610428
    Abstract: This variable-response magnetic radiofrequency device integrated into a substrate comprises: a beam that is mobile relative to the substrate having, at each end, a transversal part mechanically anchored to the substrate and at least one central arm connecting the transversal parts to each other, at least one of the transversal parts being made out of a piezoelectric material, actuating electrodes associated with the piezoelectric material to apply a stress on the central arm, a magnetic element directly deposited on the central arm whose permeability varies as a function of the stress, and a conductive strip comprising a central part fixed to an upper face of the magnetic element opposite the lower face of this magnetic element pointed towards the central arm.
    Type: Grant
    Filed: November 15, 2010
    Date of Patent: December 17, 2013
    Assignees: Commissariat a l'Energie Atomique et aux Energies Alternatives, Centre National de la Recherche, Universite Brest-Bretagne Occidentale
    Inventors: Bernard Viala, Smaali Rafik, Patrick Queffelec, Evangeline Benevent, Jean-Philippe Michel
