The Electronic Nose Artificial Olfaction Technology Book Pdf Download. 2014 edition this book provides the basics of odor odor analysis techniques sensors used in odor analysis and overview of odor measurement techniques. An electronic nose consists of a mechanism for chemical detection such as an array of electronic sensors and a mechanism for pattern recognition such as a neural network. The sensor technology of artificial olfaction had its beginnings with the invention of the first gas multisensor array in 1982.

The stages of the recognition process are similar to human olfaction and are performed for identification comparison quantification and other applications including data storage and retrieval. The electronic nose relies on pattern recognition and therefore cannot identify unknown or unexpected compounds. Artificial olfaction technology biological and medical physics biomedical engineering 2014 edition kindle edition this book provides the basics of odor odor analysis techniques sensors used in odor analysis and overview of odor measurement techniques.

An artificial olfaction system may be used as substitute for mammal olfaction system and efforts are made to use e nose to do similar tasks which includes detection and discrimination. Tin oxide detectors conducting polymers eg. Common types of chemical sensing arrays are metal oxides sensors eg.

The electronic nose is engineered to mimic the human olfactory system. It also includes material from early to latest technology research available in the market of e nose era. This technology is still in the early stages of development.

The book includes a special chapter dedicated to practical implementation of e nose sensor devices with software utility which guides students to prepare projects and work in practical analysis. Artificial olfaction technology biological and medical physics biomedical engineering softcover reprint of the original 1st ed. Electronic nose e nose is basically used to detect and differentiate between odorants.

However hedonic evaluation is a specificity of the human nose given that it is related to subjective opinions. Machine olfaction is complicated by the fact that e nose devices to date have had a limited number of elements whereas each odor is produced by own unique set of potentially numerous odorant compounds. Electronic nose sensor types the basic concept of an electronic nose or machine olfaction is a measurement unit that generates complex multi dimensional data for each measurement combined with a pattern recognition technique that interprets the complex data and relates it to a target value or class.

Advances in aroma sensor technology electronics biochemistry and artificial intelligence made it possible to develop devices capable of measuring and characterizing volatile aromas released from a multitude of sources for numerous applications.
