Triboelectric nanogenerators (TENGs), serving as an innovative energy harvesting technology, have garnered significant attention and demonstrated promising potential applications across internet of things and artificial intelligence. However, developing an efficient and rational power management circuit (PMC) remains a significant challenge, primarily attributed to the limited energy transmission efficiency. Here, we propose a universal and effective strategy that can achieve lossless energy transmission between TENGs and PMCs by using the inherent capacitor of the TENG as the excitation source for the PMC. Additionally, we attain high-charge output (1.24 mC m⁻²) and high-voltage output (7200 V) simultaneously by harnessing the space charge accumulation effect and increasing the thickness of the triboelectric layer. More importantly, a high energy output of 4.24 J m⁻² cycle⁻¹ is achieved in the HV–HQ energy cycle by eliminating spark discharge at the synchronous switch. This groundbreaking work perfectly addresses the unavoidable low energy transmission efficiency issue, and provides a new methodology for achieving high-performance TENGs to power electrical devices.

同时实现高性能摩擦纳米发电机，同时实现高电压和高电荷能量循环


摩擦纳米发电机 （TENG） 作为一种创新的能量收集技术，引起了广泛关注，并在物联网和人工智能领域显示出有前景的潜在应用。然而，开发高效合理的电源管理电路 （PMC） 仍然是一个重大挑战，这主要是由于能量传输效率有限。在这里，我们提出了一种通用且有效的策略，通过使用 TENG 的固有电容器作为 PMC 的激励源，可以在 TENG 和 PMC 之间实现无损能量传输。此外，通过利用空间电荷积累效应和增加摩擦电层的厚度，我们同时实现了高电荷输出 （1.24 mC ^m-2） 和高压输出 （7200 V）。更重要的是，通过消除同步开关处的火花放电，在 HV-HQ 能量循环中实现了 4.24 J ^{m-2 cycle-1} 的高能量输出。这项开创性的工作完美地解决了不可避免的低能量传输效率问题，并为实现高性能 TENG 为电气设备供电提供了一种新方法。
