论文摘要
电子电视机有可能实现独立护理（POC）设备的潜力。在这里，我们报告了液滴迁移特征，该特征是在液压上（EWOD）底物的。我们准备稀疏的微柱以保留油层，以利用该层作为润滑膜。开发了液滴速度的物理模型，并讨论了润滑，油粘度，液滴体积以及固体和液体介电层的厚度。发现将液滴速度缩放为E的平方，这与E的滴度与液滴的关系不同，用于通过重力在液体注入的表面上滑落。此外，我们的设备在15 V的施加电压下达到1 mm/s的液滴速度。在基于多孔结构的液体液体液体液体表面上，速度约为相同的条件（施加电压和油粘度）的十倍。实现的高速度通过润滑流效应来解释。
Electrowetting has a potential to realize stand-alone point-of-care (POC) devices. Here we report droplet-migration characteristics on oil-infused electrowetting-on-dielectric (EWOD) substrates. We prepare sparse micropillars to retain the oil layer in order to exploit the layer as a lubricating film. A physical model of the droplet velocity is developed, and effects of the lubrication, the oil viscosity, the droplet volume, and the thickness of solid and liquid dielectric layers are discussed. It is found that the droplet velocity is scaled as square of E, which differs from a relationship of cube of E for droplets sliding down on liquid-infused surfaces by gravity. Furthermore, our device achieves droplet velocity of 1 mm/s at the applied voltage of 15 V. The velocity is approximately tenfold as high as the same condition (applied voltage and oil viscosity) on porous-structure-based liquid-infused surfaces. The achieved high velocity is explained by a lubrication-flow effect.
