Imagine a drop of water lying on a surface, pulled into a ball by surface tension. With electricity it is possible to change the shape of the drop and cause it to flatten out. This is electrowetting, a physical phenomenon which has aroused great interest in recent years as it has found new applications. Here we will describe the phenomenon and two of its applications: variable-focus liquid lenses and paper-thin, video-rate, reflective color displays.
想象一滴水落在一个表面上，由于表面张力而被拉成球状。利用电可以改变水滴的形状，使其变平。这就是电润湿，一种近年来引起极大兴趣的物理现象，因为它有了新的应用。在这里，我们将描述这种现象及其两个应用：可变焦距液体透镜和薄如纸、视频速率的反射式彩色显示器。
