Abstract
An oscillation apparatus comprising: a frame; a first proof mass coupled to the frame via a spring; a driving circuit operatively coupled to the first proof mass and the frame, wherein the driving circuit is configured to induce oscillatory motion of the first proof mass relative to the frame at a resonant frequency in a first direction; a first electron-tunneling position switch operatively coupled to the first proof mass such that the first position switch is configured to pass through a closed state during each oscillation of the proof mass, wherein the position switch comprises first and second single-atom-thick tunneling electrodes; and a sensing circuit coupled to the position switch, the sensing circuit configured to output a signal whenever the position switch passes through the closed state.
