Electrostatic nonlinear dispersive parametric mode interaction

Understanding and controlling the nonlinear coupling in micro/nanomechanical resonators are of great importance to exploitation advanced devices. The recently observed electrostatic parametric is a very interesting topic. However, theoretical model remains unclear. This paper explicitly derives electrostatically induced dispersive which reveals ability tune bifurcation topology capacitive analyzed based on multiple-time-scale method. A novel displacement-to-frequency transduction scheme this effect proposed. sensitivity theoretically given, indicates that can provide even more design freedoms than existing tension modulation. In addition, reversal predicted strong actuated states coupled system, resonators.
