A review of gas sensors employed in electronic nose applications
This paper reviews the range of sensors used in electronic nose (e-nose) systems to date. It outlines the operating principles and fabrication methods of each sensor type as well as the applications in which the different sensors have been utilised. It also outlines the advantages and disadvantages of each sensor for application in a cost-effective low-power handheld e-nose system.doi:10.1108/02602280410525977 fatcat:vqnjqzwehvf5bonf2p2hsxtna4
