T and quality controls in plastic packaging. Recently it findsits applications in medical diagnosis, specifically on detection of diabetes, pulmonary or gastrointestinal problem, orinfections by examining odors in the breath or tissues with its odor characterizing ability. Moreover, the use of portablee-nose enables the on-site measurements and analysis of vapors without extra gas-sampling units. This is expected to widenthe application of the e-nose in various fields including point-of-care-test or e-health. In this study, a PDA-based portablee-nose was developed using micro-machined gas sensor array and miniaturized electronic interfaces. The rich capacitiesof the PDA in its computing power and various interfaces are expected to provide the rapid and application specificother facilities through information technology (IT) infra.For performance verification of the developed portable e-nose system, Six diferent vapors were measured using thesystem. Seven different carbon-black polymer composites were used for the sensor array. The results showed thereproducibility of the measured data and the distinguishable patterns between the vapor species. Additionally, theapplication of two typical pattern recognition algorithms verified the possibility of the automatic vapor recognition fromthe portable measurements. These validated the portable e-nose based on PDA developed in this study.
