Gas sensors are now widely employed in many industries due to the rapid speed of industrialization and the growth of the Internet of Things. However, the wearability and mobility of traditional gas sensors are limited by their high reliance on external power sources. Nanogenerators (NGs) can compensate for their power source limitations when paired with gas sensors by transforming the environment's widely dispersed low-frequency energy into electrical energy, allowing for self-powered gas detection. The paper thoroughly examines the advancements made in the field of NG-based self-powered gas sensor research in recent years. A systematic description is given of the two main types of NG-based self-powered gas sensors. Lastly, the evolution of sensor use in a few typical gas sensing applications is highlighted, and the field's future development trend is anticipated.
由于工业化的快速发展和物联网的增长，气体传感器目前在许多行业中得到广泛应用。然而，传统气体传感器的可穿戴性和移动性受到其对外部电源高度依赖的限制。纳米发电机（NGs）与气体传感器配对时，可以通过将环境中广泛分散的低频能量转化为电能来弥补其电源限制，从而实现自供电气体检测。本文全面审视了近年来基于纳米发电机的自供电气体传感器研究领域取得的进展。系统描述了基于纳米发电机的自供电气体传感器的两种主要类型。最后，突出了传感器在一些典型气体传感应用中的发展，并预测了该领域的未来发展趋势。
