Gas Sensors

Materials and devices
Jianmin Ma


Gas sensors are traditionally used as part of an industrial safety system, but they are also increasingly found in a range of settings including home and vehicle security, ventilation systems and environmental monitoring. The technology also holds great promise in non-invasive medical applications and as an essential component in the future Internet of Things. Metal oxide semiconductors are the most common materials exploited for gas sensing. However, in recent years there have been significant advances in both fundamental research and industrial development of gas sensors using new and novel materials. This is being driven by efforts to achieve better selectivity, higher sensitivity and lower power consumption as gas sensors are finding more widespread applications. This book reviews the developments and applications of traditional and emerging materials for gas sensors. Each chapter considers a sensor material and discusses the mode of operation, intrinsic material properties, preparation, device construction and areas of application opened by the novel modes of action and properties of the sensing material. With coverage spanning n- and p-type metal oxides, graphene, 2D metal chalcogenides, carbon nanotubes, ionic liquids and conducting polymer composites. This up-to-date synthesis will provide invaluable reading for industrial and academic researchers and engineers developing and exploiting new materials for the increasingly diverse areas of applications for modern gas sensors.
