Highly sensitive and rapid responding humidity sensors based on silver catalyzed Ag₂S–TiO₂ quantum dots prepared by SILAR

Abstract

Ag2S@TiO2 films was made as humidity sensors by SILAR method. The heterojunction and nano-silver improve the electrons transfer and increase the response and reaction rate. It also provides high gas selectivity to avoid effect of air pollution.

Ultrasensitive stretchable bimodal sensor based on novel elastomer and ionic liquid for temperature and humidity detection

“…The matrix is later used in the fabrication of the bimodal sensor. From the TH-matrix data, it's found that the sample has a highest sensitivity of 4.4%/RH% under the temperature of 30 °C, which is 3 times more than previously reported resistive moisture sensors, which have their sensitivities in the range of 1–2%/RH% at maximum [ [38] , [39] , [40] , [41] ]. Detailed comparison is shown in Table S2 .…”

Ag2S-Decorated One-Dimensional CdS Nanorods for Rapid Detection and Effective Discrimination of n-Butanol

“…As the baseline resistance decreased, the consumption of O − reduced its reactivity with the target gas, resulting in a decline in sensor response. In addition, according to the reported literature, the resistance value of Ag 2 S is greatly affected by water molecules and can be used as a sensitive material for humidity sensors [ 45 , 46 ], which is also a reason why the ACS-3 sensor was significantly affected by humidity. To mitigate the effects of humidity in practical applications, humidity compensation can be implemented to minimize the disparities in sensor response under varying humidity conditions.…”
