“…In case of multi-element arrays responses of individual sensors to the same gas mixture could be very different. A characteristic pattern ("fingerprint") of mixture could be created in that way [16].…”

BTEX compounds can cause a threat to environment and human health. For this reason measurement devices are needed for rapid identification of such pollutants. The paper presents the results of recognition of mixtures of benzene, toluene, ethylbenzene and xylenes in humid air by means of two gas sensor arrays and linear discriminant analysis. Measurements were conducted during stabilization/solidification processes of contaminated soils. High classification ratios were obtained for both arrays (I: 88%-94%; II: 94%-96%). Improvement of identification was achieved when two copies of every sensor were included in analysisclassification rates reached 97.1-100%.

“…For example, the methodology of signal processing from the outputs of commercial FIGARO ® sensors has been proposed for food quality testing [ 72 , 73 ]. Using chemiresistive sensors, a platform was built for odor measurement, evaluated based on data and feature analysis, and applied in the development of an odor classification system [ 74 – 78 ]. Certain low-cost electronic nose systems are designed for indoor air-quality monitoring [ 79 ]; furthermore, combining them with a wireless module enables real-time online odor detection [ 80 ].…”

Electronic noses have potential applications in daily life, but are restricted by their bulky size and high price. This review focuses on the use of chemiresistive gas sensors, metal-oxide semiconductor gas sensors and conductive polymer gas sensors in an electronic nose for system integration to reduce size and cost. The review covers the system design considerations and the complementary metal-oxide-semiconductor integrated technology for a chemiresistive gas sensor electronic nose, including the integrated sensor array, its readout interface, and pattern recognition hardware. In addition, the state-of-the-art technology integrated in the electronic nose is also presented, such as the sensing front-end chip, electronic nose signal processing chip, and the electronic nose system-on-chip.
