Piezoelectric resonant-based mechanical frequency combs

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, a method comprises driving a piezoelectric mechanical resonator with an electrical AC signal, wherein the electrical AC signal causes motion of the piezoelectric mechanical resonator; and producing at least one phononic frequency comb in response to the motion of the piezoelectric mechanical resonator.
