| description | This study focuses on a novel humidity sensor composed of graphene-oxide (GO)-supported MoTe<sub>2</sub> nanosheets. Conductive Ag electrodes were formed on PET substrates by inkjet printing. A thin film of GO-MoTe<sub>2</sub> was deposited on the Ag electrode used for adsorbing humidity. The experiment’s results demonstrate that MoTe<sub>2</sub> are attached to GO nanosheets uniformly and tightly. The capacitive output of the sensors with various ratios of GO/MoTe<sub>2</sub> has been tested for different levels of humidity (11.3–97.3%RH) at room temperature (25 °C). As a consequence, the obtained hybrid film exhibits superior sensitivity (94.12 pF/%RH). The structural integrity and interaction of different components were discussed to afford the prominent humidity sensitivity performance. Under the bending condition, the output curve of the sensor has no obvious fluctuation. This work provides a low-cost way to build flexible humidity sensors with high-performance in environmental monitoring and healthcare. |
