Electronic Nose: Algorithmic Challenges


Book Description

This book presents the key technology of electronic noses, and systematically describes how e-noses can be used to automatically analyse odours. Appealing to readers from the fields of artificial intelligence, computer science, electrical engineering, electronics, and instrumentation science, it addresses three main areas: First, readers will learn how to apply machine learning, pattern recognition and signal processing algorithms to real perception tasks. Second, they will be shown how to make their algorithms match their systems once the algorithms don’t work because of the limitation of hardware resources. Third, readers will learn how to make schemes and solutions when the acquired data from their systems is not stable due to the fundamental issues affecting perceptron devices (e.g. sensors). In brief, the book presents and discusses the key technologies and new algorithmic challenges in electronic noses and artificial olfaction. The goal is to promote the industrial application of electronic nose technology in environmental detection, medical diagnosis, food quality control, explosive detection, etc. and to highlight the scientific advances in artificial olfaction and artificial intelligence. The book offers a good reference guide for newcomers to the topic of electronic noses, because it refers to the basic principles and algorithms. At the same time, it clearly presents the key challenges – such as long-term drift, signal uniqueness, and disturbance – and effective and efficient solutions, making it equally valuable for researchers engaged in the science and engineering of sensors, instruments, chemometrics, etc.

Nanotechnology-Based E-Noses


Book Description

Nanotechnology-based E-Noses reviews advances in nanomaterials and their modification for use in e-sensors. "E-noses" or "electronic sensors" are emerging as advanced technologies for the fast detection of chemicals, gases, and explosives. The concept behind the "e-nose" is similar to the capability of humans and dogs in detecting materials based on odors. Nanomaterials can be used for e-nose technologies but their properties must be modified to make them effective sensors. The sensing capability and performance of these materials depend on several factors, such as morphology, dopants, microadditives, design of sensors, phase, and structure of the nanomaterials. Theoretical understanding of nanomaterials and technologies for improving sensors with better detection limits are covered. The most relevant nanomaterials, their synthesis strategies, and the relationship between properties and device performance are provided. Current state-of-the-art progress in nanotechnology device fabrication along with directions for future applications and challenges are discussed. - Covers fundamentals of nanomaterials for electronic sensing applications, including material synthesis and property optimization strategies to improve material performance - Reviews emerging relevant nanomaterials including 1D, 2D and 3D nanomaterials for use in e-nose technologies - Discusses nanotechnology-based e-noses and their wide range of applications in the detection of chemicals, gases, explosives, and more
