Humidity sensors have been widely applied to detect environment humidity in various fields. However, most of humidity sensors cannot provide performance needed for high sensitivity and fast response. We report one type of capacitive-type humidity sensors composed of laser-scribed graphene (LSG) as sensing electrodes and graphene oxide/tin dioxide (GO/SnO₂) as a sensing layer. The LSG is reduced graphene oxide (rGO) electrodes resulted from selective reducing of GO within a GO/SnO₂ composite layer by laser scribing method, and the sensing layer is the un-scribed GO/SnO₂ composite. The sensor fabrication is a one-step process which is facile and cost-efficient. When a mass ratio of GO: SnO₂ in the composite reaches 1:1, the humidity sensor (named as LSG-GS₁) has the best properties than other ratios, which exhibits high sensitivity in the range of 11%~97% relative humidity (RH). In addition, the LSG-GS₁ also has very quick response/recovery time (20 s for adsorption and 18 s for desorption) when RH changes from 23% to 84%, and very good stability after monitoring for 41 days. Such excellent performances of the humidity sensor can be attributed to synergistic effect of SnO₂ and GO within the composite layer.
