Book Description :

There were two reasons that induced me to plan and to organize this book, the first was the lack of a text entirely devoted to the subject of gas sensors, notwithstanding some books devoted to the various kind of chemical sensors have recently been published. The second reason was the need of introducing the basic topics of gas detection mechanisms to a growing number of researchers active in research and development laboratories of industries and uni versities. The field of chemical sensors is indeed in fast and consistent growth, as it is proved by the increased number of participants to the congresses that were recently held on this subject, namely the Third Meeting on Chemical Sensors (September 24 - 26, 1990, Cleveland), Transducers' 91 (June 24 - 27, 1991, S. Francisco) and EUROSENSORS V (September 30 - October 3, 1991, Rome). Therefore, this book is mainly intended as a reference text for researchers with a MS degree in physics, chemistry and electrical engineering; it reports the last progresses in the R. & D. and in the technology of gas sensors. I choose to deal specifically with the topic of gas sensors because these devices show a very large number of applications in the domestic and industrial field and they are characterized by a great effort of research and development.

Book Description :

The only practical way to imitate human nose function is via gas sensors which monitor air quality and provide a mean to premature alert of potential risk. A gas sensor can form a part of an early warning system, notifying the appropriate authorities or provide the feedback signal to a process control system. To achieve this, the gas sensor must be accurate and stable in-situ real time measurements. It is foreseen that hydrogen energy will form the infrastructure that will power future societies since it is a clean, cost-effective and renewable source of energy. However, hydrogen, being flammable gas, has a lower expolsion limit of 4% in air meaning that even a small spark can ignite the mixture. Therefore, hydrogen generation, transport and storage can be dangerous if not handled with caution. This requires high precision sensitive gas sensors which are able to detect the smallest leaks fastly. Semiconductor Metal Oxide gas sensors are an important candidate for this task.

Book Description :

Gas sensor technology has advanced remarkably during past few decades and has become one of the indispensable technologies for modern society. Varieties of gas sensors are commercially available and, using innovative ideas, efforts are being made to develop gas sensors of next generation having very small size with very low power consumption. The ultimate model for this is probably given by sensory organs of our own body, which are implanted finely and work well with a very modest amount of energy. In order to achieve this goal, it is essential that various aspects of gas sensors are seriously considered. These include understanding of gas sensing mechanisms, development of new materials and methods to synthesise them into selective sensors, innovations in nanostructured materials, measurement methods, microfabrication of sensors, exploring intelligent sensing system, etc. This book examines these issues pertaining to chemiresistive gas sensors.

Book Description :

This book examines the potential application of semiconductor materials for gas sensor production on the basis of their fundamental, theoretical, and experimental studies. Some of these materials or their composites were applied for semiconductor gas sensor production for the first time. Special attention is paid to the model materials A2B6, which are used in the form of films with biographic surface as well as with the surface doped by donor (In, Cd, Sn, Pt, Pd etc.) and acceptor (Se and others) particles. Results of application of metal-oxide materials as adsorptionally sensitive elements are also represented in this book. These elements were produced and tested in the form of simple oxides (as SnO2, In2O3, for example) as well as in the form of composite oxide metal complexes (SnWO4, ZnO:In2O3 etc.). The book examines in detail the influence of doping on different materials and their adsorption sensitivity, persistence, selectivity, dynamic and kinetic characteristics, and other parameters. Results of thorough studies of degradation of semiconductor sensor material characteristics, when in working gas atmospheres, are represented in a special section of the book. Adsorptionally sensitive parameters of amorphous silicon, micro-, macro- and nanoporous silicon are examined and results of Si structure testing as gas sensors are also discussed in this book.

Book Description :

Research and development of solid state gas sensor devices began in the 1950s with several uncoordinated independent efforts. The number and pace of these investigations later accelerated in response to increasing pressure placed on the environment and public health by industrial activities. Since 1970, several thousand articles have been written on the subject, and laboratories around the globe have introduced novel methodologies and devices to address needs associated with particular technological developments. Despite the rapid development of this important new technology, very little has been done to review and coordinate data related to sensor science and technology itself. Physics, Chemistry and Technology of Solid State Gas Sensor Devices focuses on the underlying principles of solid state sensor operation and reveals the rich fabric of interdisciplinary science that governs modern sensing devices. Beginning with some historical and scientific background, the text proceeds to a study of the interactions of gases with surfaces. Subsequent chapters present detailed information on the fabrication, performance, and application of a variety of sensors. Types of sensor devices discussed include: Gas-sensitive solid state semiconductor sensors Photonic and photoacoustic gas sensors Fiber optic sensors Piezoelectric quartz crystal microbalance sensors Surface acoustic wave sensors Pyroelectric and thermal sensors For analytical chemists using solid state sensors in environment-related analysis, and for electrical engineers working with solid state sensors, this book will expand and unify their understanding of these devices, both in theory and practice.

Book Description :

Metal Oxide Nanostructures as Gas Sensing Devices explores the development of an integrated micro gas sensor that is based on advanced metal oxide nanostructures and is compatible with modern semiconductor fabrication technology. This sensor can then be used to create a compact, low-power, handheld device for analyzing air ambience. The book first covers current gas sensing tools and discusses the necessity for miniaturized sensors. It then focuses on the materials, devices, and techniques used for gas sensing applications, such as resistance and capacitance variations. The author addresses the issues of sensitivity, concentration, and temperature dependency as well as the response and recovery times crucial for sensors. He also presents techniques for synthesizing different metal oxides, particularly those with nanodimensional structures. The text goes on to highlight the gas sensing properties of many nanostructured metal oxides, from aluminum and cerium to iron and titanium to zinc and zirconium. The final chapters deal with existing and future devices that are based on nanostructures. Miniaturized systems that analyze air ambience need sensors capable of identifying different gaseous species. Exploring state-of-the-art gas sensing devices, this book shows how nanostructured metal oxides are ideally suited for use as gas sensing elements.

Book Description :

Advanced Gas Sensing focuses on the Electroadsorptive Effect: its theory, experimental measurement and applications in consumer gas sensors as well as in surface physics laboratory work. The Electroadsorptive Effect is invaluable when used in MEMS gas sensors. The authors use a general approach that covers new insights into temperature modulation and the use of light. The emphasis is given to electrical fields in gas sensors, which cause the Electroadsorptive Effect. The effect has long been known by experts working in the field, but has been regarded as too difficult for use until recently because of increasing sensor miniaturization. The book will serve as an introduction to sensitivity tuning of semiconductor gas sensors, introducing the underlying theory and experimental models before moving on to design considerations, applications and market considerations. A literature review and examples of experimental data are included.
