Odor Sensor

Odor-Based Incontinence Sensor

A low-cost “artificial nose” is required to monitor incontinence of elderly patients in nursing homes. With the aim of identifying a small array of inexpensive sensors whose response vector could provide an unambiguous signature at a useful sensitivity level, we characterized the sensitivity of seven easily available solid-state sensors to fecal component gases and vapors, and to potential inte...

Sensor fusion for taste sensor and odor sensor.

Recent research on a taste sensor stimulated the development of several kinds of sensing systems that have the ability to discriminate various tastes of beverages or foods. Most of these sensors involve the concept of global sensing, i.e. non-specifically detected signals are analyzed to extract the inherent taste characteristics (Toko, 1996). The sensor fusion technique extends the global sens...

Odor to sensor space transformations in biological and artificial noses

Pattern Recognition for Selective Odor Detection with Gas Sensor Arrays

This paper presents a new pattern recognition approach for enhancing the selectivity of gas sensor arrays for clustering intelligent odor detection. The aim of this approach was to accurately classify an odor using pattern recognition in order to enhance the selectivity of gas sensor arrays. This was achieved using an odor monitoring system with a newly developed neural-genetic classification a...

Power Scaling of Chemiresistive Sensor Array Data for Odor Classification

Abstract The steady state responses of chemical sensors like the tin-oxide and composite conducting polymer sensors exhibit power law dependency on the vapor concentration. In this research, it is shown that linearization of measured (raw) sensor signals by an inverse power scaling improves class separability in feature space, hence the classification efficiency of electronic noses based on the...
