本文描述和表征了电润湿诱导液滴在不混溶介质中的运动。当一个水性液滴在橄榄油的连续相中经历电润湿诱导的运动时，液滴以比在没有油的情况下可能的速度高得多的速度滑过橄榄油，并且能够行进大于电极间隔距离的10倍。为了描述这种行为，开发了一个简单的流体动力学模型来预测液滴速度并阐明液滴运动的机制。在此模型的基础上，我们还讨论了减少液滴分裂的策略。
This paper describes and characterizes the electrowetting-induced movement of droplets in an immiscible medium. When an aqueous droplet undergoes electrowetting-induced motion in a continuous phase, of olive oil, the droplet glides through the olive oil at a much higher velocity than is possible in the absence of oil and is able to travel greater than 10 times the electrode separation distance, To describe this behavior, a simple hydrodynamic model is developed to predict the droplet speed and to elucidate the mechanism of droplet movement. On the basis of this model, we also discuss a strategy to reduce droplet splitting.
