Many research groups in academia and industry are focusing on the performance
improvement of electronic nose (E-nose) systems mainly involving three optimizations …

Conventional approaches to chemical sensors have traditionally made use of a “lock-and-
key” design, wherein a specific receptor is synthesized in order to strongly and highly …

Acetone, as widely used reagents in industry and laboratories, are extremely harmful to the
human. So the detection of acetone gas concentrations and leaks in special environments at …

Sensor drift remains to be the most challenging problem in chemical sensing. To address
this problem we have collected an extensive dataset for six different volatile organic …

Metal oxide (MOX) gas sensors arrays are a predominant technological choice to perform
fundamental tasks of chemical detection. Yet, their use has been mainly limited to relatively …

Signal and data processing are essential elements in electronic noses as well as in most
chemical sensing instruments. The multivariate responses obtained by chemical sensor …

Pattern analysis constitutes a critical building block in the development of gas sensor array
instruments capable of detecting, identifying, and measuring volatile compounds, a …

Chemical sensor arrays have come to have an important role in the analysis of volatile
analytes. Such arrays gather data which have broad, overlapping sensitivity profiles, which …

Desired properties of a chemical sensor include high sensitivity, a large dynamic range, high
selectivity or specificity to a target analyte, related low cross-sensitivity to interferents, perfect …

Engineering approaches designed to improve the parameters of conductometric gas
sensors, are considered in this short survey. In particular, in the first part of the paper we …
