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 …

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 …

The human olfactory system remains one of the most challenging biological systems to
replicate. Humans use it without thinking, where it can measure offer protection from harm …

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, overlap** sensitivity profiles, which …

With growing transportation and population density, increasing global warming and sudden
climate change, air quality is one of the critical measures that is needed to be monitored …

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 …

This paper presents a network for indoor and outdoor air quality monitoring. Each node is
installed in a different room and includes tin dioxide sensor arrays connected to an …

Abstract The Self-Organizing Map (SOM) algorithm has attracted a great deal of interest
among researches and practitioners in a wide variety of fields. The SOM has been analyzed …

Drift is an important issue that impairs the reliability of gas sensing systems. Sensor aging,
memory effects and environmental disturbances produce shifts in sensor responses that …
