Magnetic polymeric composite has variable capacitance based on the adjustable arrangement of magnetic particles controlled by magnetic field. Considering the capacitive effect on the surface charge density of tribo-materials has important influence on the output performance of TENG, it is of great significance to study the magnetic polymeric composite as the tribo-material of TENG from a microscopic perspective.

Here, an approach of using a magnetic polymeric composite film as the tribo-material is proposed to effectively enhance the output performance of TENG (M-TENG). After studying the influence of the cured magnetic flux density, filling particle concentration and particle size, a sustainable and enhanced output of 32.6 μA (short-circuit current) and 233.4 V (open-circuit voltage) were obtained, and a peak output power of 2.5 mW was gained from the M-TENG under a loading resistance of 3 MΩ, giving over 4.7-fold enhancement than the TENG which was based on the pure silicone rubber mixture film (0.53 mW).

Finally, a real-time automatic target-scoring system was constructed to illustrate the practical value of M-TENG as a self-powered sensor.

磁性聚合物复合材料基于受磁场控制的磁性颗粒的可调排列，具有可变的电容。考虑到电容对摩擦材料表面电荷密度的影响对TENG的输出性能有重要影响，因此从微观角度研究磁性聚合物复合材料作为TENG的摩擦材料具有重要意义。

在此，提出一种使用磁性聚合物复合膜作为摩擦材料的方法，以有效地提高TENG（M-TENG）的输出性能。在研究了固化磁通量密度，填充颗粒浓度和颗粒大小的影响之后，获得了持续且增强的32.6μA（短路电流）和233.4 V（开路电压）输出，峰值输出功率为在3MΩ的负载电阻下，从M-TENG获得2.5 mW的能量，比基于纯硅橡胶混合物薄膜的TENG（0.53 mW）增强了4.7倍。

最后，构建了一个实时自动目标评分系统，以说明M-TENG作为自供电传感器的实用价值。
