E-Nose System by Using Neural Networks

Neurocomputing, 2014
This paper considers a new construction of an electronic nose (E-nose) system based on a neural network. The neural network used here is a competitive neural network by the learning vector quantisation (LVQ). Various odors are measured with an array of many metal oxide gas sensors.

Embedded e-nose for food inspection

2012 1st International Symposium on Physics and Technology of Sensors (ISPTS-1), 2012
This 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.

Anesthetic Level Prediction Using a QCM Based E-Nose

Journal of Medical Systems, 2008
Anesthetic level measurement is a real time process. This paper presents a new method to measure anesthesia level in surgery rooms at hospitals using a QCM based E-Nose. The E-Nose system contains an array of eight different coated QCM sensors. In this work, the best linear reacting sensor is selected from the array and used in the experiments.

Spiking Neural Network E-Nose classifier chip

Proceedings of the IEEE 2010 National Aerospace & Electronics Conference, 2010
Hardware E-Nose system classification is a challenging task. This paper presents our system architecture for chemical classifiers, with our recently developed Sampling Spiking Neural Network (SSNN) approach. The SSNN architecture is implemented on a 0.5 um CMOS technology tiny-chip designed to work in conjunction with a 256K external SRAM memory.
