Triboelectric-electromagnetic hybrid nanogenerator (HNG) with high output performance provides a very promising solution for realizing self-powered microelectronic devices. However, the complex structures and large mass of traditional HNGs make them difficult to prepare and carry. In this study, a rotating HNG based on flexible neodymium iron boron/ethyl cellulose (NdFeB/EC) composite films was designed for wind energy scavenging. A lightweight composite film with triboelectric and ferromagnetic properties, which can significantly reduce the weight of the rotor, was prepared to replace the magnet. Operated at a wind speed of 15.5 m/s, the triboelectric nanogenerator (TENG) unit of the optimized HNG with an interdigitated electrode gap of 2 mm can generate an open-circuit voltage (V_oc) and a short-circuit current (I_sc) of 55 V and 5.4 μA, respectively. The maximum power of TENG is 99.2 μW under the condition of an external load resistance of 10 MΩ. The corresponding electromagnetic generator (EMG) unit can produce V_oc and I_sc of approximately 0.16 V and 59.3 μA, delivering an output power of 2.5 μW at a matched loading resistance of 2.3 kΩ. Compared to the individual TENG or EMG units, the HNG exhibited better charging performance. A 470 μF capacitor can charge to 3.4 V within 600 s, and the stored energy can successfully power a commercial soil temperature–humidity meter to work continuously for 75 s and light 30 blue LEDs in parallel. This research is of great scientific significance for developing triboelectric–ferromagnetic dual-functional materials and designing highly integrated and lightweight HNGs.

具有高输出性能的摩擦电-电磁混合纳米发电机（HNG）为实现自供电微电子器件提供了非常有前景的解决方案。然而，传统HNG结构复杂、质量大，导致其制备和携带困难。在这项研究中，设计了一种基于柔性钕铁硼/乙基纤维素（NdFeB/EC）复合薄膜的旋转HNG，用于风能清除。制备了一种具有摩擦电和铁磁性能的轻质复合薄膜来代替磁体，可以显着减轻转子的重量。在风速为 15.5 m/s 时，优化的叉指电极间隙为 2 mm 的 HNG 的摩擦纳米发电机 (TENG) 单元可产生开路电压 (V _oc ) 和短路电流 (I _sc）分别为55V和5.4μA。在外部负载电阻为10 MΩ的情况下，TENG的最大功率为99.2 μW。相应的电磁发生器 (EMG) 单元可产生约 0.16 V 和 59.3 μA 的 V _oc和 I _sc，在 2.3 kΩ 的匹配负载电阻下提供 2.5 μW 的输出功率。与单独的 TENG 或 EMG 单元相比，HNG 表现出更好的充电性能。 470 μF 电容器可以在 600 秒内充电至 3.4 V，所存储的能量可以成功为商用土壤温湿度计供电，使其连续工作 75 秒并并行点亮 30 个蓝色 LED。该研究对于开发摩擦电-铁磁双功能材料以及设计高度集成、轻量化的HNG具有重要的科学意义。
