Future advanced wearable energy harvesters need to have high power densities, functionality under large deformations, scalability, and robust resistance against mechanical damages (i.e. fatigue, delamination, and fracture). To achieve this, ultra-flexible, high dielectric, and thermally conductive materials along with deformable and robust electrodes are needed. Here, we review recent progress in synthesis and integration of liquid metal (LM) material architectures as the building blocks of emerging wearable energy harvesting devices. After a brief introduction to room temperature LM alloys, LM’s various applications in a variety of soft and stretchable power harvesting devices including thermoelectric, triboelectric, dielectric elastomer, and piezoelectric generators are summarized. The unique opportunities and challenges introduced by LM material architectures in this field are also discussed.

未来的先进可穿戴式能量采集器需要具有高功率密度，大变形下的功能性，可扩展性以及对机械损伤（即疲劳，分层和断裂）的强大抵抗力。为此，需要超柔性，高介电和导热材料以及可变形且坚固的电极。在这里，我们回顾了液态金属（LM）材料结构的合成和集成的最新进展，这些结构是新兴的可穿戴式能量收集设备的基础。在简要介绍了室温LM合金之后，总结了LM在各种软性和可拉伸功率收集设备中的各种应用，包括热电，摩擦电，介电弹性体和压电发电机。
