Design of a Portable E-Nose Instrument for Gas Classifications
IEEE Transactions on Instrumentation and Measurement, 2009In this paper, a portable instrument is developed for a qualitative discrimination among different gas samples. The system is able to implement various gas measurement protocols entered by a user, display incoming online samples during an observation, and display classified gas sets from several observations.

E-Nose Algorithms and Challenges
2018This chapter focuses on the up-to-date progress and development in algorithm level for E-nose. We discuss from the viewpoint of feature extraction algorithms, signal de-noising algorithms, pattern recognition algorithms, and drift compensation algorithms that have been fully studied in electronic noses.

Embedded e-nose for food inspection
2012 1st International Symposium on Physics and Technology of Sensors (ISPTS-1), 2012This paper details development of a low cost, small size, portable embedded electronic nose (e-nose). The odor Sensor array is composed of commercially available metal oxide semiconductor sensors by Figaro. The embedded E-nose consists of PIC18F4520 and has an RS 232 interface to Desktop PC for data acquisition, storage and analysis of the odor signals.

Biologically Inspired Pattern Recognition for E-nose Sensors
2016The high sensitivity, stability, selectivity and adaptivity of mailman olfactory system is a result of a large number of olfactory receptors feeding into an extensive layers of neural processing units. Olfactory receptor cells (ORC) contribute significantly in the sense of smells.

Performance of an e-nose in hops classification
Sensors and Actuators B: Chemical, 2004A prototype of an electronic nose (e-nose), based on an array of six undoped and doped SnO2 gas sensors made by the rheotaxial growth and thermal oxidation (RGTO) technique, is applied to the analysis of a basic ingredient of beer, the hop. We address two main requirements from the local brewing industry: to detect departures from the hop’s quality due
