Currently, triboelectric nanogenerators (TENGs) based on chitosan materials face challenges such as limited output power and suboptimal mechanical performance, restricting their application in biodegradable wearable devices and smart homes. Quartz fiber, an inorganic amorphous dielectric material known for its excellent mechanical robustness, thermal resilience, and electrical insulating characteristics, can positively impact the charge properties of chitosan films. Therefore, an innovative chitosan/quartz fiber TENG (CQ-TENG) has been developed by combining quartz fiber embedding and PVA blending techniques to effectively address the high brittleness and low output performance of chitosan-based TENGs. The interaction between chitosan and quartz fibers increases the number of polarization centers, enhancing the charge retention capacity of the CQ-TENG. As a result, the CQ-TENG achieves a time-averaged power density of 37.8 mW/m
