The team also demonstrated for the first time that if the electrostatic actuator delivers a small
mechanical force to the PMO that varies in time while the
system undergoes these self - sustaining oscillations, the PMO can lock onto that
tiny variable signal and greatly amplify it.
It offers new ways to miniaturize
mechanical oscillators, improve communication
systems that depend on the modulation of light, dramatically amplify extremely weak
mechanical and electrical signals and create exquisitely sensitive sensors for the
tiny motions of nanoparticles.
