چکیده

Inductive micro-switch is an integrative device of a sensor and actuator and widely applied in all-opticalnetwork communication. Its malfunctions related to “fail-to-closure” and “transient-closure” result in low reliability and weak anti-jamming capability. A new bistable inductive micro-switch is presented based on micro electro-mechanical system (MEMS) technology. A sine rough surface model is used to describe the random distribution of the rough adhesive surface. Micro size Casimir and van der Waals (vdW) forces are analyzed in detail. The vdW force includes the repulsive force. Dynamic simulation results are shown to be in agreement with experimental results. The threshold acceleration was 6.8g, and the response time was 17.5μs. A “double-snap-back” phenomenon in the Off-state is discovered.

Study on the Pull-In Instability of Gold Micro-Switches Using Variable Length Scale Parameter

In this paper, the size dependent behavior of the gold micro-switches has been studied. This behavior becomes noticeable for a structure when the characteristic size such as thickness or diameter is close to its internal length-scale parameter. The size dependent effect is insignificant for the high ratio of the characteristic size to the length-scale parameter, which is the case of the silicon...

Robust Lyapunov-based Control of MEMS Optical Switches

In this paper, a robust PID control scheme is proposed for Micro-Electro-Mechanical-Systems (MEMS) optical switches. The proposed approach is designed in a way which solves two challenging and important problems. The first one is successful reference tracking and the second is mitigating the system nonlinearities. The overall system composed of nonlinear MEMS dynamics and the PID controller is ...

Couple Stress Effect on Micro/Nanocantilever-based Capacitive Gas Sensor

Micro/nanocantilevers have been employed as sensors in many applications including chemical and biosensing. Due to their high sensitivity and potential for scalability, miniature sensing systems are in wide use and will likely become more prevalent in micro/nano-electromechanical systems (M-NEMSs). This paper is mainly focused on the use of sensing systems that employ micro/nano-size cantilever...
