Patent ID: 8610428

Claim:
A variable-response magnetic radiofrequency device integrated into a substrate, said variable-response magnetic radiofrequency device comprising: a beam that is mobile relative to the substrate, said beam having, at each end thereof, 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, the magnetic element having a permeability that varies as a function of the stress, and a conductive strip placed on only one side of the beam, said conductive strip being electromagnetically coupled to the magnetic element, wherein the conductive strip comprises a central part fixed to an upper face of the magnetic element opposite a lower face of the magnetic element, said strip being pointed towards the central arm.
