Chemosensory adaptation in an electronic nose

Proceedings 2nd Annual IEEE International Symposium on Bioinformatics and Bioengineering (BIBE 2001), 2001
This article presents a computational mechanism inspired by the process of chemosensory adaptation in the mammalian olfactory system. The algorithm operates on multiple subsets of the sensory space, generating a family of discriminant functions for different volatile compounds.

Sensors and Microsystems: Electronic Nose

1997
This Chapter has two purposes: The first purpose is to illustrate in some detail a design of an advanced chemical microsystem, also called a micro total analysis system (μTAS) 1 which can use either surface acoustic wave or optical chemical sensors in the test chamber, and which can be fabricated by silicon micromachining technology and semiconductor ...

Overview of electronic nose algorithms

IJCNN'99. International Joint Conference on Neural Networks. Proceedings (Cat. No.99CH36339), 2003
The electronic nose is a natural match for physiologically motivated odor analysis. Both the olfactory system and the electronic nose consist of an array of chemical sensing elements and a pattern recognition system. This paper reviews different approaches to chemical data analysis (i.e., chemometrics) found in both commercial and experimental ...

The Electronic Nose for Process Control

1995
Considerable commercial interest has recently been given to the electronic nose technology. Integrating it with neural networks offers the potential for use in the process control industries, controlling processes on the basis of odour assessments.

Electronic Noses for Bioreactor Monitoring

1999
Electronic noses provide new possibilities for monitor the state of a cultivation non-invasively in real-time. The electronic nose uses an array of chemical gas sensors that monitors the off-gas from the bioreactor. By taking advantage of the off-gas components' different affinities towards the sensors in the array it is possible with the help of ...

Electronic Nose and Electronic Tongue

2015
The sensations of smell and taste resulting from a series of specific and nonspecific molecular recognition can be used as an analytical tool in many industries to measure the quality of food, drinks, and chemical products. In a few cases, there are olfactory receptor s or gustatory receptors which are specific for individual chemical molecules ...

Electronic Noses in Food Analysis

2001
Gas sensor array technology combined with multivariate data processing methods as artificial neural network has been demonstrated to have a promising potential for rapid non-destructive analysis of food quality. It may be applicable in quality control of raw material, food processing or products.

The Strengths and Weaknesses of the Electronic Nose

2001
Arrays of electronic sensors, capable of detecting and differentiating complex mixtures of volatile compounds, have been utilized to differentiate aromas of food and related materials. These sensor arrays have been dubbed "Electronic Noses" and have been commercially available in the USA for the past 4-5 years.
