摘要:

毛细波推进器作为一种新型动力装置在无人船舶、医疗机器人等领域有着应用前景，然而其能量供给方式与推力特性之间的关系有待深入探索。本文提出一种基于摩擦纳米发电机的毛细波推进器，其可利用环境中的风能、波浪能等作为能量源，驱动介电润湿单元产生毛细波，并利用反推力推进船舶。在输出电压520V，频率5Hz的情况下，成功实现对一重量为3.42g的泡沫船实现推进。本文探索了一种不依赖传统能源与结构的新型船舶推进模式，为今后轻型船舶的动力提供了新的解决思路。

Abstract:

As a new type of power system， capillary wave propeller possesses great potential for unmanned boat and medical robots. The relationship between the power supply and propulsion performance of the capillary wave propeller requires in depth exploration. A triboelectric nanogenerator powered capillary wave propeller is investigated in this study. The triboelectric nanogenerator could utilize the environmental energy such as wind and wave to drive the electrowetting propeller to generate capillary wave， the repulsive force of the capillary wave could be employed for propulsion. When the triboelectric nanogenerator outputs at 520V and 5Hz， a 3.42g expanded polystyrene boat was propelled forward. A new propulsion model that does not rely on traditional energy and structure is investigated in this study， which provides a new solution for the propulsion of lightweight ships in the future.
