| Research Abstract |
Bistable states of the vibration amplitude of micro/nano-resonators are realized using its mechanical nonlinearity. Those resonators exhibit stochastic resonance state by applying external noise, in addition, respond to external stimulus. It is shown that the resonators can be applicable to robust sensors. For same purpose, an array of resonators with self-sensing function has been developed. In addition, possibility of mechanical logic devices has been shown using mechanically coupled resonators.
