Characterization of novel sensing materials for Volatile Organic Compound detectionThe ability to detect, distinguish and categorize odors finds valuable uses in several fields such as automotive, industrial safety and consumer products. Volatile Organic Compounds (VOCs) are of particular relevance in these fields, as key components of many complex mixtures of gases to be detected. The electronic nose (e-nose) is a device which mimics the functionalities of the human nose through an array of gas sensors coupled with machine learning algorithms. One class of sensors used to detect low gas concentrations are the metal-oxide-semiconductor (MOX) gas sensors, sensors which change their conductivity upon gas exposure.
