Metal-oxide has come into view as an encouraging choice in the gas sensor industry. This review paper focuses on the ammonia sensing principle of the metal oxides. It also includes various approaches adopted for increasing the gas sensitivity of metal-oxide sensors. Increasing the sensitivity of ...
One of the challenges for semiconductor metal oxide gas sensors is to achieve high selectivity. Generally two approaches exist for enhancing the selectivity of a SMO gas sensor. The first one is to synthesize a material which is selective to one compound and has very low or zero cross-sensitivi...
