Miniature sensor suitable for electronic nose applications
Publication: Research - peer-review › Journal article – Annual report year: 2007
A major research effort has been devoted over the years for the development of chemical sensors for the detection of chemical and explosive vapors. However, the deployment of such chemical sensors will require the use of multiple sensors probably tens of sensors in a sensor package to achieve selective detection. In order to keep the overall detector unit small, miniature sensors with sufficient
sensitivity of detection will be needed.We report sensitive detection of dimethyl methylphosphonate
DMMP, a stimulant for the nerve agents, using a miniature sensor unit based on piezoresistive microcantilevers. The sensor can detect parts-per-trillion concentrations of DMMP within 10 s exposure times. The small size of the sensor makes it ideally suited for electronic nose
applications. © 2007 American Institute of Physics.
