Energy management strategy is the essential approach for achieving high energy utilization efficiency of triboelectric nanogenerators (TENGs) due to their ultra-high intrinsic impedance. However, proven in practical applications remains low, and output regulation functionality still lacking. Herein, we propose a detailed transfer extraction mechanism addressing voltage charge losses caused by crucial switches circuits. The conversion increased 8.5 times through synergistical optimization TENG switch configurations. Furthermore, TENG-based power supply with storage regularization functions realized system circuit design, demonstrating stable powering electronic devices under irregular mechanical stimuli. A rotating that only works 21 s can make hygrothermograph work stably 417 s. Even hand driving, various types TENGs consistently provide such as calculators mini-game consoles. This provides an in-depth between circuits, also addresses technical challenge converting unstable into usable electricity field. Effective enable realistic applications. Here, authors optimize configurations improve design functionalities.
