Gas Sensors based on Conducting Metal Oxides: Basic Understanding, Technology and Applications focuses on two distinct types of gas sensors based on conducting metal oxides. Ion conduction, applied in so-called solid-state electrolytic sensors for one, and electronic conduction used in semiconductivity gas sensors for the other. The well-known ?-probe, a key component to optimize combustion in car engines, is an example of the former type, and the in-cabin car air-quality control SnO2 and WO2 sensor array stands for the semiconductivity type. Chapters cover basic aspects of functioning principles and describe the technologies and challenges of present and future sensors.
  • Provides reader background and context on sensors, principles, fabrication and applications
  • Includes chapters on specific technological applications, such as exhaust sensors, environmental sensors, explosive gases alarms and more
  • Presents a structured presentation that allows for quick reference of vital information

Barsan, Nicolae
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.
