From Carbon Monoxide Detection to the Artificial Electronic Nose: A Review of Technologies and Applications
The presentation will focus on a comprehensive review of artificial olfactory systems, commonly known as electronic noses (e-noses). It will begin with an overview of the operating principles and structural design of e-noses, highlighting the differences between chamber-based and chamberless configurations. Various types of gas sensors will be discussed, and the rationale for employing sensor arrays instead of single detectors in practical applications will be explained, emphasising their role in improving selectivity and sensitivity.
The presentation will then explore different construction approaches to e-noses, including the design of sensing chambers and their influence on measurement stability and repeatability. A wide range of practical applications will be presented, from carbon monoxide detection to the classification of coffee varieties, cigarette types, and fuel samples.
A significant portion of the talk will be devoted to environmental and biological applications of e-noses, such as estimating the population density of forest pests like the pine-tree lappet moth (Dendrolimus pini), and detecting plant diseases. Case studies will include the detection of fungal infections in cereal grains, the identification of root pathogens in oak seedlings, and the recognition of ash seedling infections through soil analysis.
The seminar will demonstrate the interdisciplinary nature of electronic nose research, combining elements of electronics, analytical chemistry, environmental biology, and machine learning methods, and will highlight the growing potential of this technology in both scientific and industrial domains.
