Abstract: Chemical sensors, an important green sensor, in view of the relation of the structure-sensitive and the physico-chemistry interaction with the surrounding environment for the point defects on the change of chemical surrounding in redox, additive and optical-electro-color fields are the key of the new applications and new developments in this paper. The knowledge of how the point defects influence the ceramics/device performance was revealed and provides very useful tools for understanding their basic characteristics and to open up their potentiality of the new applications in the near future.

Key words: green sensor, point defect, oxygen vacancy, chemical bound, Brouwer-KrOger-Vink diagram
