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.

Опубликована: Март 26, 2024

Abstract The triboelectric nanogenerator (TENG) holds significant potential for applications in energy harvesting and environment monitoring. However, a notable challenge lies developing combined system capable of efficiently providing real‐time self‐powered sensing. Here, wind speed sensing (EHSS) is constructed based on noncontact electricity‐induced constant‐voltage TENG (EICV‐TENG) that achieves constant output by coupling two different phases incorporates parasitic module single phase. Through the optimization integration, EICV‐TENG current density 28.7 mA m −2 an average power 0.26 W Hz −1 . With optimal management, efficiency reaches up to 96%. And can stably 32 commercial hygrothermographs connected parallel with PMC at 7 s In addition, EHSS demonstrates excellent performance correlation between peak number pulse phase speeds. This work contributes advancement technology context Internet Things (IoTs).
