  • Method and device for suppressing hysteresis of resonators through simultaneous resonance
    Patent number: 8653716
    Abstract: An electromechanical resonator including: at least one deformable element, and at least one electrode that simultaneously supplies, to the at least one deformable element, at least one first actuating force at a first frequency, and a second actuating force at a second frequency, the first and the second frequencies creating at least two simultaneous resonances with a primary resonance at a frequency ?0 equal to the first frequency and the second frequency being equal to a subharmonic resonant frequency (k?0, with k>1) of the resonator, or to a superharmonic resonant frequency (?0/k, with k>1).

  • METHOD AND DEVICE FOR SUPPRESSING HYSTERESIS OF RESONATORS THROUGH SIMULTANEOUS RESONANCE
    Publication number: 20110221301
    Abstract: The invention relates to an electromechanical resonator including at least one deformable element, actuating means for this deformable element for applying to it, simultaneously, at least one first actuating force at a first frequency, and a second actuating force at least one second frequency, the first and second frequencies creating at least two simultaneous resonances at a frequency equal to the frequency of one of the actuating forces.
