Modular design and fully packed triboelectric nanogenerator based on escapement mechanism for harvesting high entropy energy in harsh environments

Hui Li et al.

Summary: This study presents a self-powered system composed of modular triboelectric nanogenerators (M-TENG) and power management circuit (PMC) to efficiently capture high entropy energy (HEE) in harsh environments and provide stable output. By optimizing the gear train, weak HEE can produce greater torque to drive the escapement, which evenly releases energy to the TENG for stable and continuous electrical output. The influence of various structural parameters on the M-TENG's output performance has been systematically investigated and validated using finite element analysis (FEA). The M-TENG demonstrates a maximum open-circuit voltage (VOC) of 500 V, short-circuit current (ISC) of 6 μA, and transfer charges (QSC) of 125 nC. Furthermore, the stability and environmental adaptability of the M-TENG have been quantitatively validated. This work provides a paradigm for efficiently utilizing HEE in harsh environments and inspires the development of emergency self-rescue equipment.
