Compact and/or MEMS-based gas-sampling sensors for analysis of battery offgassing

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.
