Abstract: In present article, typical 3S parameters of gas sensors that are sensitivity, selectivity and stability of metal oxides are discussed. Metal oxide gas sensors are considered as one of the basic technology for identification and measuring concentration of gases in atmosphere. Research on sensing materials has been focused on design higher performance and elevated efficiency gas sensing materials. Various experimental methodologies associated with gas sensors are discussed for their screening in this article. In present review we confined our dissection with inorganic materials. Factors deals with sensitivity and selectivity are discussed including inorganic materials such as Transition-metal oxides and Non-transition-metal oxides.


Keywords: Sensitivity, Selectivity, Stability, Inorganic materials
