基于分水岭算法的电润湿特性研究

Investigation on Properties of EWOD Based on Watershed Algorithm

采用一种改进的分水岭变换算法研究导电液滴在微流控芯片表面介质上电润湿效应,获得了一个单像素宽度、连续的液滴边缘轮廓,得到了导电液滴在芯片表面的接触角随外加电势的变化规律,进而计算了导电液体的表面张力。相关结论为新型微流控光学变焦透镜阵列器件的设计和研制提供了依据。

The properties of electrowetting on dielectric （EWOD） on the core-surface of optofluidic are investigated with an improved watershed algorithm. A single-pixel width, continuous profile is acquired. The variation of the contact angle value with voltage is obtained, and the interracial tension coefficient of the droplet is derived. The relevant conclusions are valuable in the field of the design and development of new types of optofluidic zoom lens array devices.
