Abstract

Magnetic Materials

A key challenge in monitoring electric power transmission systems is reliably powering compact sensors, particularly due to the difficulty of delivering low-power wiring from high-voltage (kV-level) transmission lines. In article number 2500856, Jungho Ryu, Jeong Min Baik, Hyun-Cheol Song, and co-workers developed a high-performance magneto-mechano-triboelectric energy harvester that can be conformally mounted on power lines and harvest energy from stray magnetic fields. This conformal and lightweight solution addresses the limitations of conventional bulky and rigid energy harvesters, providing a practical route toward self-powered sensing in high-voltage environments.

用于独立电力线物联网应用的无形状因数磁摩擦发电机（Adv. Energy Mater. 25/2025）

磁性材料监测电力传输系统的一个关键挑战是可靠地为紧凑型传感器供电，特别是由于从高压（kv级）输电线路输送低功率线路的困难。在2500856号文章中，Jungho Ryu, Jeong Min Baik， Hyun-Cheol Song及其同事开发了一种高性能磁-机械-摩擦电能量采集器，可以保形安装在电力线上并从杂散磁场中收集能量。这种保形和轻量级的解决方案解决了传统笨重和刚性能量采集器的局限性，为高压环境下的自供电传感提供了一条实用的途径。
