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 Sn O2 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
