Thermal Compensated Pull-in Voltage MEMS Inclinometers
Procedia Engineering, 2014 AbstractThe study of temperature effects on pull-in voltage-based inclinometers is reported here. A 75μ°-resolution MEMS inclinometer that uses pull-in voltages as the transduction mechanism is tested at different temperatures and inclinations. The microstructures used have differential actuation electrodes enabling the measurement of two pull-in ...

Stability of a micromechanical pull-voltage reference
IEEE Transactions on Instrumentation and Measurement, 2003 The reproducibility over temperature and time of the pull-in voltage of micromechanical structures has been analyzed and verified using fabricated devices in silicon. The pull-in structures are intended for use as an on-chip voltage reference. Microbeams of 100-/spl mu/m length, 3-/spl mu/m width, and 11-/spl mu/m thickness are electrostatically ...
