The increasing importance of gas detection has led to extensive research on flexible and transparent high-performance gas sensors. We have developed a sensor for NO2 detection at room temperature, utilizing screen printing on a flexible substrate and coating MoS2 and single-walled carbon nanotubes (SWCNT) on a specific area through the self-assembly method. This fabrication process is rapid, easy, and cost-effective. The proposed sensor enables precise and stable NO2 gas sensing from 50 ppb to 100 ppm, and it could potentially be used for the selective detection of other gases.
The rising importance of gas detection has prompted rigorous research on flexible and transparent high-performance gas sensors. We demonstrated a sensor for NO2 detection at room temperature, in which our device was fabricated via screen printing on a flexible substrate, and MoS2 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 NO2 gas sensing from 50 ppb to 100 ppm. This method should also be applicable to the selective detection of other gases.
