众所周知，人体皮肤和头发在与其他材料摩擦时容易失去电子，产生静电。这种天然再生物质在摩擦电系列中占有很高的地位。尽管可再生自然物质的静电在人类历史上一直是一个长期的好奇心，但目前还不清楚它们的哪种成分导致了正静电荷。这项研究表明，再生物质（皮肤，头发，树叶，细胞）表面的脂质层甚至合成脂质都是这种正静电的原因，并表明有可能制造基于脂质的摩擦电纳米发电机（TENG）。利用叶片上的脂质在几个小时内再生的特性，从活树叶中收集脂质，并制造基于脂质的无损TENG。还提出了能量收集藤蔓的概念，当它们松散地缠绕在活树枝上时可以发电。这项研究提出了如何在保护自然的同时获得电力。
It is familiar to everyone that human skin and hair easily lose electrons and cause static electricity as they undergo friction with other materials. Such natural regenerative substances take a high ranking in the triboelectric series. Even though the static electricity of regenerative natural substances has been a long-term curiosity in human history, it is not yet clear which of their components causes the positive static charges. This study reveals that lipid layers on the surface of regenerative substances (skin, hair, leaves, cells) and even synthetic lipids are responsible for this positive static electricity and shows that it is possible to manufacture lipid-based triboelectric nanogenerators (TENGs). Using the characteristic that lipids on leaves regenerate within a few hours, lipids from living tree leaves are collected, and lipid-based nondestructive TENGs are fabricated. The concept of energy-harvesting vines is also presented, which can generate electricity when they are wrapped loosely on living tree branches. This study suggests how to harvest electricity while preserving nature as it is.
