Wireless system for the detection and monitoring of diseases through exhaled breath

Abstract

This article presents the analysis and design of a wireless system for the monitoring and detection of diseases through exhaled breath in people; This system comprises of a sampling device which contains a measuring chamber composed of MOS gas sensors, in order to detect the volatile compounds emitted from the breath for biomedical applications. A high-performance wireless data acquisition card sends the obtained signals to a remote terminal, which will incorporate a graphical set of pattern recognition algorithms (e.g PCA) and artificial intelligence for pre-processing and signal processing to find the patterns of the volatile compounds for discrimination and classification.
