NOS.E: A New Fast Response Electronic Nose Health Monitoring System

We present a practical electronic nose (e-nose) sys-tem, NOS.E, for the rapid detection and identification of human health conditions. By detecting the changes in the composition of an individual’s respiratory gases, which have been shown to be linked to changes in metabolism, e-nose systems can be used to characterize the physical health condition. We demonstrated our system’s viability with a simple data set consists of breath collected under three different scenarios from one volunteer. Our preliminary results show the popular classifier SVM can discriminate NOS.E’s responses under the three scenarios with high performance. In future work, we will aim to gather a more varied data set to test NOS.E’s abilities.
