Compact and/or MEMS-based gas-sampling sensors for analysis of battery offgassing Navy SBIR FY2010.1 Sol No.: Navy SBIR FY2010.1 Topic No.: N101-056 Topic Title: Compact and/or MEMS-based gas-sampling sensors for analysis of battery offgassing Proposal No.: N101-056-1479 Firm: Agiltron Corporation 15 Cabot Road Woburn, Massachusetts 01801-1003 Contact: Anton Greenwald Phone: (781) 935-1200 Web Site: http://www.agiltron.com Abstract: Agiltron proposes to develop an integrated stand-alone multiple gas sensor for small spaces suitable for detection of gases emitted from batteries. The proposed composite gas sensor is based on multiplexed wavelength modulated tunable diode laser absorption spectroscopy (TDLAS). Using multiple diode lasers that are tuned to the near infrared absorption band of the gases, the sensor will accurately determine low-concentration composition of the atmosphere around it. Although table top multiple gas optical sensors have been demonstrated, small stand-alone units have yet to be developed for commercial-scale production. The laser package, optics, and electronics expertise of Agiltron would allow us to develop a system that overcomes the remaining hurdles for the commercial-scale production of multiplexed composite gas sensors. Benefits: The anticipated sensor would fulfill an immediate need to monitor outgassing from batteries and increase crew safety. Modified for other gas mixtures, it could be used as an instrument for monitoring all sealed or poorly ventilated spaces in vessels, buildings, aircraft, sealed containers, etc. detecting hazardous fumes, fire, leaks, and personnel.
