面向轻体无人船舶的自供能毛细波推进器研究

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自供能推进方式，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520 V，频率5 Hz的情况下，成功实现对一重量为3.42 g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。

Self-Powered Light-Weight Unmanned Boat Propulsion Based on Capillary Wave

Light-weight unmanned boat shows great potential in environmental monitoring, inspection, and confined spaces exploration. Traditional propulsion system heavily relies on large-amplitude and high-frequency power sources, which not only increases the system investment, but also limit the applications with portable requirement. A triboelectric nanogenerator powered light-weight unmanned boat propulsion 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 520 V and 5 Hz, a 3.42 g 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.
