The utilization of various distributed energy is becoming a prominent research topic due to the rapid development of the Internet of Things and wireless condition monitoring systems. Among the various distributed energy sources, wind energy has the advantages of being widely distributed, renewable and pollution-free, and is a very promising mechanical energy for power supply. Traditional wind energy harvesting methods based on electromagnetic and piezoelectric effects have issues with complex structure, large size, severe mechanical structures, and high installation costs. The low frequency and irregular nature of ambient mechanical energy makes these methods generally inefficient and inevitably hinders the further exploitation of wind energy. The triboelectric nanogenerators (TENGs) based on frictional charging and electrostatic effects can also be used for wind power generation and are increasingly favored by researchers as TENGs are easier to be miniaturized and assembled, and can realize large-scale manufacturing in comparison.
由于物联网和无线状态监测系统的快速发展,各种分布式能源的利用正在成为一个突出的研究课题。在各种分布式能源中,风能具有分布广泛、可再生、无污染等优点,是一种非常有前景的电力供应机械能。传统的基于电磁和压电效应的风能收集方法存在结构复杂、体积大、机械结构严密、安装成本高等问题。环境机械能的低频和不规则性质使得这些方法通常效率低下,不可避免地阻碍了风能的进一步开发。基于摩擦充电和静电效应的摩擦电纳米发电机(TENGs)也可用于风力发电,并且由于TENG更容易小型化和组装,并且可以实现大规模制造,因此越来越受到研究人员的青睐。本文综述了TENGs在风能利用结构设计、材料选择和潜在应用等方面的研究进展。此外,还总结并讨论了该领域的潜在困难和可能的发展。
