Beschreibung

Digital Olfaction main idea is to create devices which not only can capture odors, but also turn them into digital data as well as transmit them everywhere in the world and restitute the original odor. The first phase of Digital Olfaction could be performed by the so called Electronic noses, that could be defined as “an instrument which comprises an array of electronic chemical sensors with partial specificity and appropriate pattern recognition system, capable of recognizing simple or complex odors” [1]. These devices could be applied in various sectors, such as agriculture and livestock, industrial processes, perfume industry, environmental toxin/pollutant analysis, space stations, medical/healthcare, pharmaceuticals, forensic science, military, toxicology/security and the food and beverage industry.
 This seminar tries to describe the main technologies involved in Electronic nose systems and showing the last prototypes [2-4] and applications [5-8] carried out in the Perception and Smart Systems group of University of Extremadura.
