我们提出并演示了一种基于液滴的新型热开关，该热开关采用共面介质电润湿（EWOD）结构，用于卫星热控制。通过制造和测试概念验证器件，我们确认了热开关液滴的分离和附着机理。热试验表明，该材料在水和甘油作用下具有良好的热性能。进一步开发具有低蒸汽压和高导热系数的新型液体有望改善性能。
We propose and demonstrate a novel liquid-droplet-based thermal switch aimed for satellite thermal control by using coplanar electro-wetting-on-dielectric (EWOD) configuration. By fabricating and testing the proof-of-concept devices, we confirm the mechanism of droplet detaching and attaching for the thermal switches. Thermal tests have shown the reasonable thermal performance with water and glycerin. Further development with novel liquid with low vapor pressure and high thermal conductivity is expected to improve the performance.
