QCL and MEMS device enables real-time monitoring and sensing of atmospheric explosive vapors

Feb. 29, 2016
Researchers have developed a multimodal sensing system for explosive vapors that uses a microthermometer/microheater device (see figure) and a widely tunable quantum cascade laser (QCL). To further enhance the sensitivity and selectivity of the MEMS devices, they will integrate a compact micro preconcentrator in the same chip to achieve higher vapor collection efficiency for target explosive vapors.
