“…The experimental results suggested that rGO is a promising material for improving the performance of GaN-based gas sensors. Metal oxide semiconductor materials, such as ZnO [ 18 , 19 ], SnO 2 [ 20 , 21 ], CuO [ 22 , 23 ], and Ag 2 O 3 [ 24 , 25 , 26 ], have a broad range of application prospects in the field of flexible gas sensors with the advantages of a simple preparation method, a controllable morphology, environmental friendliness, a low price, and stable physical and chemical properties. Mokrushin et al [ 27 ] synthesized highly dispersed ZnO powders doped with europium and praseodymium by the solvothermal method.…”

Reduced graphene oxide (rGO) fiber as a carbon-based fiber sensor has aroused widespread interest in the field of gas sensing. However, the low response value and poor flexibility of the rGO fiber sensor severely limit its application in the field of flexible wearable electronics. In this paper, a flexible and wearable nylon fiber sensor modified by rGO and ZnO quantum dots (QDs) is proposed for wide-range NO2 gas detection at room temperature. The response value of the nylon fiber sensor to 100 ppm NO2 gas is as high as 0.4958, and the response time and recovery time are 216.2 s and 667.9 s, respectively. The relationship between the sensor’s response value and the NO2 concentration value is linear in the range of 20–100 ppm, and the fitting coefficient is 0.998. In addition, the test results show that the sensor also has good repeatability, flexibility, and selectivity. Moreover, an early warning module was also designed and is proposed in this paper to realize the over-limit monitoring of NO2 gas, and the flexible sensor was embedded in a mask, demonstrating its great application potential and value in the field of wearable electronics.
