很早以前,人们就发现了“摩擦起电”的现象,如尺子在头皮上摩擦后可吸起碎纸屑。当时的人们一定想不到,在若干年后的今天,这样小小的摩擦也能聚集成供人类使用的能源。摩擦纳米发电机摩擦能源的利用有赖于摩擦纳米发电机(Triboelectric Nanogenerator,简称TENG)的发明。它是一种利用材料之间摩擦引起的电荷转移,将机械能转化成电能,实现能量收集和转换的发电设备。 A long time ago, people discovered the phenomenon of “triboelectric charge”, such as the ruler scraping the scalp after sucking up the shredded paper. People at that time could not have imagined that, after a few years, such a small friction can also be gathered into energy for human use. Friction nano-generator Frictional energy utilization depends on the triboelectric nano-generator (Triboelectric Nanogenerator, referred to as TENG) invention. It is a kind of power generation equipment that uses the charge transfer caused by the friction between materials, and converts the mechanical energy into electric energy to realize energy collection and conversion.
