Abstrakt: The rising importance of gas detection has prompted rigorous research on flexible and transparent high-performance gas sensors. We demonstrated a sensor for NO 2 detection at room temperature, in which our device was fabricated via screen printing on a flexible substrate, and MoS 2 and single-walled carbon nanotube (SWCNT) were coated on a specific area by the self-assembly method. This fabrication process is rapid, facile, and cost-effective. The proposed sensor enables precise and stable NO 2 gas sensing from 50 ppb to 100 ppm. This method should also be applicable to the selective detection of other gases.
