TLDR
In this paper, the authors investigated the nonlinear dynamics of microcantilevers and showed that at strong driving, the cantilever amplitude is bistable and suggested several applications for the bistability of the canticle.Abstract:
We investigate the nonlinear dynamics of microcantilevers. We demonstrate mechanical stiffening of the frequency response at large amplitudes, originating from the geometric nonlinearity. At strong driving the cantilever amplitude is bistable. We map the bistable regime as a function of drive frequency and amplitude, and suggest several applications for the bistable microcantilever, of which a mechanical memory is demonstrated.read more
