The technique of fluctuation-enhanced sensing (FES) in resistive gas sensors was proposed a few years ago. The method improves the selectivity and sensitivity of gas detection. This was confirmed in numerous laboratory experiments. Some of the latest results obtained for practical applications of the FES method are presented (toxic gases detection; problems of detection repeatability; detection of...
There is a continuous demand on improving detection of different gas mixture in the food processing industry, medicine and military applications by using inexpensive measurement equipment. The newly proposed method can increase sensibility and selectivity of gas detection in Taguchi gas sensors by observing resistance noise of gas sensors instead of their DC resistance only. The observed fluctuations...
