Sensors and Microsystems: Electronic Nose
1997This 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 ...

Electronic Nose and Electronic Tongue
2015The 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 for Bioreactor Monitoring
1999Electronic 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 Noses in Food Analysis
2001Gas 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
2001Arrays 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.

Electronic nose instrumentation
1999Abstract The basic elements of a generalised electronic instrument system to measure odours are shown schematically in Fig. 8.1. First there is an odour delivery system which is designed to transfer the odour from the source material to the sensor chamber. There are two main ways in which the odour can be delivered to the sensor chamber,
