摘要

海浪是一种很有前途的可再生能源,但由于技术限制,收集这种不规则的低频能量具有挑战性。提出了一种基于摆板的摩擦纳米发电机(PP-TENG)。PP-TENG通过安装在设备底部的摆板吸收波浪能量,产生摆动效应。这驱动了上部TENG发电单元的运动,并在聚合物聚四氟乙烯和尼龙薄膜表面产生电荷转移,这些材料对低频波环境非常敏感。在建立半物理模拟测试平台后,对PP-TENG进行了测试。当聚合物材料为厚度为0.01 mm的聚四氟乙烯和厚度为0.02 mm的尼龙时,可同时点亮33盏商用LED灯。在短路条件下,电流达到2.45 μA,在开路条件下,电压达到212 V。当PP-TENG与电阻3 × 105 Ω串联时,其最大峰值功率密度达到6.74 mW/m2。结果表明,PP-TENG具有制造成本低、能量转换效率高等特点。摆波能量转换器与TENG的组合显示出良好的输出性能。本研究为今后该结构的实际应用奠定了坚实的基础。

A Triboelectric Nanogenerator Based on a Pendulum-Plate Wave Energy Converter
Abstract Ocean waves are a promising source of renewable energy, but harvesting this irregular low-frequency energy is challenging due to technological limitations. In this paper, a pendulum plate-based triboelectric nanogenerator (PP-TENG) is proposed. The PP-TENG absorbs wave energy through the pendulum plate installed at the bottom of the device, which generates a swing effect. This drives the motion of the upper TENG power generation unit and generates a charge transfer on the surface of a film of polymer PTFE and nylon, materials which are very sensitive to the low-frequency wave environment. The PP-TENG was tested after building a semi-physical simulation test platform. When the polymer materials were PTFE with a thickness of 0.01 mm and nylon with a thickness of 0.02 mm, 33 commercial LED lamps could be lit simultaneously. Moreover, under short-circuit conditions, the current reached 2.45 μA, and under open-circuit conditions, the voltage reached 212 V. When the PP-TENG was connected in series with a resistor with a resistance of 3 × 105 Ω, its maximum peak power density reached 6.74 mW/m2. It can be concluded that the PP-TENG is characterised by low fabrication costs and excellent energy conversion efficiency. The combination of a pendulum wave energy converter with a TENG shows great output performance. This research lays a solid foundation for practical applications of the proposed structure in the future.
