Microelectromechanical Gas Sensor Based on Knudsen Thermal Force
Researchers at Purdue University have developed a novel, microelectromechanical gas sensor to measure both the heat transfer rate and displacement of a known ambient gas mixture. This device is based on Knudsen thermal force and uses technology that creates a thermal gradient between the heater and surrounding gas and structure. This technology is particularly valuable as it is compact, all electric, and comparatively superior to vacuum gauges in low pressure environments, making it attractive for pharmaceutical lyophilization and high-altitude UAV/spacecraft, among other applications.
