Patent ID: 8653716

Claim:
An electromechanical resonator comprising: at least one non-linearly deformable element, and actuating means for simultaneously applying, to said at least one non-linearly deformable element, at least one first actuating force at a first frequency, equal to a resonant frequency ω 0 of said resonator, and at least one second actuating force at a second frequency, equal to a subharmonic resonant frequency kω 0 , with k>1, k being an order of non linearity of the at least one non-linearly deformable element, of said resonator, or to a superharmonic resonant frequency ω 0 /k, with k>1, of said resonator, said first and second actuating forces creating at least two simultaneous resonances inducing vibrations of said at least one non-linearly deformable element at one single frequency that corresponds to the first frequency.
