Abstract
The feasibility of fluctuation-enhanced sensing (FES) for the detection and classification of different gases using a single chemiresistive microsensor has been investigated through experimental measurements and data analyses. A nanostructured semiconducting metal oxide film has been used as a chemiresistive sensor in the experiments. Similarity fingerprints have been introduced to be used with the FES signatures, and combining similarity fingerprints with slope fingerprints results in a considerable increase in the classification accuracy attained by both Linear Discriminant Analysis (LDA) and Support Vector Machine (SVM) classification techniques.
