电润湿是一种在微流体系统中实现单个液滴的运动、分配、分裂和混合的优雅方法，而不需要任何机械和容易出错的组件。通过仅施加电压，流体-固体界面的界面能被改变并且液滴的接触线被改变。然而，由于液滴形状通常严重失真，因此难以在处理期间估计液滴形状。此外，通常需要知道一个过程，在给定的几何形状上的液滴分裂是可能的，以及可以做些什么来增加系统的可靠性。因此，重要的是使用计算机模拟来获得关于对于给定电极几何形状和电压曲线的液滴的行为的理解。在考虑表面张力效应时必须特别小心。我们提出的计算机模拟表面进化程序和模板库结合图形用户界面（GUI），方便标准的任务，在模拟电润湿阵列。
Electrowetting is an elegant method to realize the motion, dispensing, splitting, and mixing of single droplets in a microfluidic system without the need for any mechanical—and fault-prone—components. By only applying an electric voltage, the interfacial energy of the fluid–solid interface is altered and the contact line of the droplet is changed. However, since the droplet shape is usually heavily distorted, it is difficult to estimate the droplet shape during the process. Further, it is often necessary to know if a process, e.g., droplet splitting on a given geometry, is possible at all, and what can be done to increase the system's reliability. It is thus important to use computer simulations to gain an understanding about the behavior of a droplet for a given electrode geometry and voltage curve. Special care must be exercised when considering surface-tension effects. We present computer simulations done with the Surface Evolver program and a template library combined with a graphical user interface (GUI) that facilitates standard tasks in the simulation of electrowetting arrays.
