有效的功率管理一直是纳米摩擦发电机实用化的难点和瓶颈。在这里，我们提出了一个通用的电源管理策略TENG最大限度地提高能量传输，直流（DC）降压转换，和自我管理机制。通过实现电源管理模块（PMM），大约85%的能量可以自主地从TENG释放，并在负载电阻上输出稳定和连续的DC电压。系统地研究了不同电路参数下的直流分量和涟漪。在1 Hz的低频下，使用PMM，TENG的匹配阻抗已以80%的效率从35 MO转换为1 M Ω，并且在对电容器充电时存储的能量已显著提高。这种策略的普遍性已经被各种具有PMM的TENG用于收集人类动能和环境机械能所极大地证明。TENG的通用电源管理策略有望成为可穿戴电子产品和工业无线网络供电的完整微能源解决方案。摩擦电与半导体的新型耦合方式，拓展了摩擦电子学的研究领域，提出了一个新的功率分支--摩擦电子学，以实现摩擦电功率的电子化管理。
Effective power management has always been the difficulty and bottleneck for practicability of triboelectric nanogenerator (TENG). Here we propose a universal power management strategy for TENG by maximizing energy transfer, direct current (DC) buck conversion, and self-management mechanism. With the implemented power management module (PMM), about 85% energy can be autonomously released from the TENG and output as a steady and continuous DC voltage on the load resistance. The DC component and ripple have been systematically investigated with different circuit parameters. At a low frequency of 1 Hz with the PMM, the matched impedance of the TENG has been converted from 35 MO to 1 M Omega at 80% efficiency, and the stored energy has been dramatically improved in charging a capacitor. The universality of this strategy has been greatly demonstrated by various TENGs with the PMM for harvesting human kinetic and environmental mechanical energy. The universal power management strategy for TENG is promising for a complete micro-energy solution in powering wearable electronics and industrial wireless networks. With the new coupling mode of triboelectricity and semiconductor in the PMM, the tribotronics has been extended and a new branch of power-tribotronics is proposed for manageable triboelectric power by electronics.
