Displacement Sensing Based on Resonant Frequency Monitoring of Electrostatically Actuated Curved Micro Beams.

The ability to control nonlinear interactions of suspended mechanical structures offers a unique opportunity to engineer rich dynamical behavior that extends the dynamic range and ultimate device sensitivity. We demonstrate a displacement sensing technique based on resonant frequency monitoring of curved, doubly clamped, bistable micromechanical beams interacting with a movable electrode. In th...

Analysis of polysilicon micro beams buckling with temperature-dependent properties

The suspended electrothermal polysilicon micro beams generate displacements and forces by thermal buckling effects. In the previous electro-thermal and thermo-elastic models of suspended polysilicon micro beams, the thermo-mechanical properties of polysilicon have been considered constant over a wide rang of temperature (20900°C). In reality, the thermo-mechanical properties of polysilicon depe...

An Electrothermally Actuated VO2-Based MEMS Using Self-Sensing Feedback Control

A self-sensing approach is used to accurately control the large displacements observed in VO2-based microelectromechanical systems actuators. The device is operated electrothermally using integrated resistive heaters. The coupling of the abrupt electrical and mechanical changes in VO2 films across its phase transition allow for the estimation of the device’s deflection by monitoring the film’s ...

Complete Characterization of Electrostatically-Actuated Beams including Effects of Multiple Discontinuities and Buckling

The entire process of calibrating an electromechanical simulator – identifying relevant parameters, designing and measuring test structures, extracting parameters using detailed electromechanical simulations, and extrapolating the behavior of an actual device – is presented. The simulation model for electrostatically-actuated beams is calibrated to a wide range of electrical and optical test st...

An Electrothermally-Actuated Bistable MEMS Relay for Power Applications

This thesis first develops a bistable mechanism that does not rely on internal stress or hinges for its bistability, which is then combined with transient electrothermal actuation and contact structure to develop a MEMS relay for power switching. The relay components, fabricated by a through etch of a silicon wafer using deep reactive ion etch (DRIE), move laterally in the plane of the wafer. T...
