Study of SnO₂ Gas Sensor Accelerated Degradation Test

Abstract

According to the reliability assessment of the SnO2 gas sensor, an accelerate degradation model was established by using temperature as the accelerated stress, the constant stress accelerated degradation testing (CSADT) was designed and conducted. The reliability of SnO2 gas sensor under the normal stress level was assessed based on pseudo life.

High-sensitive metal oxide gas sensor for BTEX gases based on ternary composite of Ce x Mn1−x O2/SnO2

“…Among various metal oxides, SnO 2 is one of the most materials for producing gas sensor due to its good chemical and thermal stability, wide operating temperature and high carrier density [15][16][17][18]. Sensors based on pristine SnO 2 , with the obvious drawbacks of poor gas response and high operating temperature [19,20], cannot meet the detection requirements. Thus, to obtain outstanding sensing performance, SnO 2 doping with other metal oxide to form heterostructure material is typically used.…”
