水波能被认为是最具发展前景的可再生能源之一，但由于技术上的诸多缺陷，目前大部分水波能尚未得到充分利用。纳米摩擦发电机作为一种新型的能源技术，在低频、随机机械能采集方面得到了广泛的应用，非常适合于收集水波能。本文提出了一种圆环结构的摩擦电纳米发电机（TS-TENG），它由一个内球和一个圆环壳组成。由水波触发，球在环面壳中旋转以产生摩擦电，TS-TENG可以从各个方向收集随机波浪能量。此外，为了获得大规模的水波能量，TS-TENG阵列被制造并呈现为用于持续为电子设备供电和为电池或电容器充电的电源。在2 Hz的搅拌频率和5度的振荡角下，预期TS-TENG可提供0.21 W/m（2）的最大峰值功率密度。TS-TENG具有成本低、环保、易于实施的优点，其开发对于大规模海洋波浪能的获取以及蓝色能源的其他潜在应用具有重要意义。
Water wave energy is regarded as one of the most prospective renewable energy sources, while most of it has not been utilized for numerous technology defects. As a new energy technology, triboelectric nanogenerator (TENG) has been widely utilized for low frequency and random mechanical energy harvesting, which is very suitable for scavenging water wave energy. In this paper, we present a torus structured triboelectric nanogenerator (TS-TENG) which consists of an inner ball and a torus shell. Triggered by water waves, the ball revolves in the torus shell for triboelectric power generation, and the TS-TENG can harvest random wave energy from all directions. Moreover, to scavenge large-scale water wave energy, the TS-TENG array is fabricated and presented as a power source for persistently powering electronic devices and charging a battery or capacitor. With an agitation frequency of 2 Hz and an oscillation angle of 5 degrees, the TS-TENG is expected to give a maximum peak power density of 0.21 W/m(2). Take advantage of low-cost, environment-friendly and easy-implement, the development of the TS-TENG is of great significance for harvesting large-scale ocean wave energy and other potential applications in blue energy.
