Abstract

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 essential oils intensity during aromatherapy, biological agent detection). Additionally, a new prototype nanoparticle gas sensor was introduced with an additional potential of gas detection using noise induced by UV irradiations.
