Description

Gas Sensors based on Conducting Metal Oxides focuses on the two most important but distinct types of gas sensors based on conducting metal oxides. Ion conduction, applied in so-called solid-state electrolytic sensors, on one side and electronic conduction which is used in semiconductivity gas sensors. The well-known λ –probe, a key component to optimize combustion in car engines, is an example of the former type; the in-cabin car air-quality control SnO2 and WO2 sensor array stands for the semiconductivity type.

Those two essential sensors are manufactured in millions and they are currently expected to solve more and more diverse problems. Advanced exhaust gas composition monitoring devices is one example of their unique applications.

Dr. Barsan and Dr. Schierbaum lead a team of subject matter experts from academic and industry backgrounds in providing the reader with chapters covering the basic aspects of functioning principles and chapters that describe technologies and challenges of present and future sensors based on metal oxides. Section I: Introduction provides useful definitions for the sensors and their analytical performance as well as discussing the importance of sensors and information about the structure of current and existing markets. Section 2: Ion conducting metal oxides based gas sensors discusses ionic conduction in solids, principles of gas detection with three phase boundaries, transduction methodologies, technological realization, and applications. Section 3: Semiconducting metal oxides based gas sensors reviews semiconducting metal oxides, modelling the gas sensing, experimental investigations, technological realization, and applications. The last section Section 4: Conclusion and outlook provides an overview of lessons learned and the potential future prospects for research on this topic.

About the Authors

Nicolae Barsan Author

He has written over 200 papers, 6 book chapters, and 13 patents. His research focuses on the understanding and application of surface interactions of materials with gases. Since 1984, when he started his scientific career at the Institute of Materials Physics and Technology in Bucharest, he has focused on the understanding of phenomena taking place at the surface of metal oxides operated in realistic conditions for gas sensing applications. He has also explored different technologies for devising better gas sensing materials and innovative sensors. He has invented the hybrid microsensor production technology based on the combination of sensing layers based on pre-processed powders and micromachined Si transducers. In 2001 he co-founded Advancing Sensing Devices (ASD) which merged with Applied Sensors and established itself as a leading European company in the field of gas sensor technology and application developments.
