Abstract With the advancements of industrialization and Internet Things (IoT), demand for gas sensing technologies has grown significantly. However, conventional sensors, which rely on external power supplies, face limitations in lifespan, capacity, replacement convenience. As a result, interest self-powered solutions grown, with triboelectric nanogenerators (TENGs) emerging as promising alternative. TENG-based sensors utilize triboelectricity, enabling detection without power. Notably, TENGs offer unique advantage integrating energy harvesting into single device. This review categorizes mechanisms two main types introduces each mechanism detail. Through case studies, it provides comprehensive understanding these sensors. Additionally, aims to analyze challenges faced by new insights research strategies, ultimately contributing advancement this technology.
