  • PIEZOELECTRIC RESONANT-BASED MECHANICAL FREQUENCY COMBS
    Publication number: 20240061315
    Abstract: The present disclosure describes systems and methods for novel phononic frequency combs and related sensing techniques realized by a piezoelectric multimode or single-mode mechanical resonator based on parametric pumping. In one embodiment of such a system, a single frequency electrical input provides an electrical signal comprising an amplitude and a single input frequency to a single-mode mechanical resonator, in which a value of the single input frequency equals twice a value of the resonance mode of the single-mode mechanical resonator. Accordingly, the mechanical resonator is configured to produce at least one phononic frequency comb in response to a motion of the mechanical resonator caused by the electrical signal.

  • Piezoelectric resonant-based mechanical frequency combs
    Patent number: 11835843
    Abstract: The present disclosure describes systems and methods for novel phononic frequency combs and related sensing techniques realized by a piezoelectric multimode or single-mode mechanical resonator based on parametric pumping. In one embodiment of such a system, a single frequency electrical input provides an electrical signal comprising an amplitude and a single input frequency to a multimode mechanical resonator, in which a value of the single input frequency equals a sum of the resonance frequencies of the two resonance modes of the mechanical resonator. Accordingly, the mechanical resonator is configured to produce at least one phononic frequency comb in response to a motion of the mechanical resonator caused by the electrical signal.
