The concept of using sensor arrays for chemical analysis gained widespread recognition in the 1980's and has continued vigorously in the 1990's. The advantages that sensor arrays offer over individual sensors are sensitivity to a wider range of analytes, improved selectivity, simultaneous multicomponent analysis, and the capability for analyte recognition rather than mere detection. By analogy with olfaction systems comprising multiple-receptors and neuronal pattern recognition, sensor arrays for gas phase detection are sometimes dubbed "electronic noses".
