Electronic Nose Full Seminar Topic Download Free and its Abstract

Enter the gas sensors of the electronic nose. This speedy, reliable new technology undertakes what till now has been impossible – continuous real monitoring of odor at specific sites in the field over hours, days, weeks or even months. An electronic device can also circumvent many other problems associated with the use of human panels. Individual variability, adaptation (becoming less sensitive during prolonged exposure), fatigue, infections, mental state, subjectivity, and exposure to hazardous compounds all come to mind. In effect, the electronic nose can create odor exposure profiles beyond the capabilities of the human panel or GC/MS measurement techniques. The electronic nose is a system consisting of three functional components that operate serially on an odorant sample- a sample handler, an array of gas sensors, and a signal processing system. The output of the electronic nose can be the identity of the odorant, an estimate of the concentration of the odorant, or the characteristic properties of the odor as might be perceived by a human.
