Digital microfluidics provides precise control of a single microdroplet, producing more opportunities for bio-molecule studies, chemical reaction and optofluidics applications. By manipulating the surface of droplets, light can be focused, scattered, or reflected toward different positions. We build a model of electro-responsive optical microfluidic system, operated based on the electrowetting mechanism, which can split or push droplets moving within a microwell. The initial close state and operated open state in a single microwell displays the color of a dye oil droplet and the substrate, respectively, represented as the dark and bright pixel in the display board. Our results indicate that the microdroplets interface could be successfully deformed and moved towards different directions within a short period of time.
数字微流控技术可对单个微滴进行精确控制，为生物分子研究、化学反应及光流体应用创造了更多机会。通过操控微滴表面，光线能够被聚焦、散射或反射至不同位置。我们构建了一种基于电润湿机制运行的电响应光学微流控系统模型，该系统能够分割或推动在微孔内移动的微滴。单个微孔中的初始闭合状态和运行时的开放状态分别显示染料油滴和基底的颜色，在显示板上分别呈现为暗像素和亮像素。我们的结果表明，微滴界面能够在短时间内成功变形并向不同方向移动。
