提出了一种基于液态金属液滴（LMD）的管状静电能量采集器，首次将LMD作为摩擦起电材料。该器件采用双螺旋电极环绕灯管获得循环转移电荷，使输出频率成倍提高，效率大大提高。由于采用管状结构，该发电机可以缠绕到使用者的手腕上，这是非常方便的收获能量从人体运动。当用户不规则摆动手臂时，输出电压可达3.52V.它为可穿戴电子产品提供了巨大的潜力。
This paper presents a liquid metal droplet (LMD) based tube-shaped electrostatic energy harvester, which for the first time, utilize LMD as tribo-electrification material. This device use double-helix electrodes around the tube to obtain cycle transferred charges which multiple output frequency and enhance efficiency tremendously. As using the tube-shaped structure, this generator can be wound up to user's wrist, which is very convenience to harvest energy from human movement. The voltage output can be reached to 3.52 V when user swung arm irregularly. It gives great potential to power up the wearable electronics.
