Conductometric Gas Sensors

The main focus of this article is to describe the basic but important perspectives of gas sensors, especially, conductometry metal oxides (MOXs). Fundamental functions, drawbacks, and factors influencing the sensor’s performances are explained. Furthermore, the enrollment of nanostructured materials and novel technology to enhance the sensing performance is also discussed. MOXs gas sensing mechanism is described to provide guidelines and knowledge to improve the sensing performances. Moreover other gas sensing devices are briefly discussed to have a clear overall picture of gas sensors.
