Magneto-mechano-electric (MME) composite devices have been used in energy harvesting and magnetic field sensing applications due to their advantages including their high-performance, simple structure, and stable properties. Recently developed MME devices can convert stray magnetic fields into electric signals, thus generating an output power of over 50 mW and detecting ultra-tiny magnetic fields below pT. These inherent outstanding properties of MME devices can enable the development of not only self-powered energy harvesters for internet of thing (IoT) systems but also ultra-sensitive magnetic field sensors for diagnosis of human bio-magnetism or others. This manuscript provides a brief overview of recently reported high-performance MME devices for energy harvesting and magnetic sensing applications.

磁机电（MME）复合材料器件因其高性能、结构简单和稳定的特性，已被应用于能量收集和磁场传感领域。最近开发的 MME 器件可以将杂散磁场转换为电信号，从而产生超过 50mW 的输出功率，并检测低于 pT 的超微小磁场。MME 器件的这些固有优异特性不仅可以为物联网（IoT）系统开发自供电能量收集器，还可以为人类生物磁或其他方面的诊断开发超灵敏磁场传感器。本文简要概述了最近报道的用于能量收集和磁场传感应用的高性能 MME 器件。
