Abstract

In this paper, we report on the mechanical coupling of the stochastic resonance (SR) in 100 nm-thick Si cantilevered resonators. Nonlinear resonators exhibit SR response by applying noise, in which the resonator shows two vibration states. The SR responses of coupled resonators are investigated, and it is found that SR is affected by each other. Moreover, the nonlinearity of each resonator can be switched by mechanical interaction via a thin Si plate. In addition, the phase of the stochastic resonance is also related to the vibration amplitude and the nonlinearity.
