As a kind of gas sensors, self-powered gas sensor shows significant advantages in large-scale applications such as the internet of things. On the other hand, triboelectric nanogenerator is an ideal power source to fabricate self-powered gas sensor for its high power output and wide variety of driving source. More importantly, it is indispensable to eliminate the influence of environmental factors considering the practical application of gas sensors. In this work, by utilizing the polymer materials with wide bandgap, a polymer based self-powered ethanol gas sensor (PB-SPES) is designed to eliminate the influence of ultraviolet (UV) light in the environment and detect the ethanol gas reliably. Compared with a zinc oxide (ZnO) based self-powered ethanol gas sensor, the PB-SPES shows good stability under UV light illumination.

自供电气体传感器作为一种气体传感器，在物联网等大规模应用中显示出显着优势。另一方面，摩擦纳米发电机由于其高功率输出和广泛的驱动源是制造自供电气体传感器的理想电源。更重要的是，考虑到气体传感器的实际应用，消除环境因素的影响是必不可少的。在这项工作中，利用宽带隙聚合物材料，设计了一种基于聚合物的自供电乙醇气体传感器（PB-SPES），以消除环境中紫外线（UV）光的影响并可靠地检测乙醇气体。与基于氧化锌 (ZnO) 的自供电乙醇气体传感器相比，PB-SPES 在紫外光照射下表现出良好的稳定性。
