A Wide Range MEMS Vacuum Gauge Based on Knudsen’s Forces

V. Sista, and E. Bhattarchaya
Microelectronics and MEMS Lab
Department of Electrical Engineering
Indian Institute of technology Madras
Chennai, India

A MEMS based Knudsen’s pressure gauge working in the range of 1e-5 mbar to 10 mbar is designed and simulated in COMSOL. The working principle is based on Knudsen’s forces that arise when two plates are held at different temperatures and their separation is comparable to the mean free ... Read More

Simulation of Thermal Sensor for Thermal Control of Satellite Using COMSOL Multiphysics

G. Mangalgiri
BITS Pilani K K BIRLA GOA CAMPUS
Zuarinagar
Goa, India

The actuator comprises of a temperature sensitive composite deflecting beam, a piezoelectric substrate and a field effect transistor. The temperature rise causes an expansion in the composite beam thereby causing it to deflect. The deflecting beam impinges on the piezoelectric crystal ... Read More
