摘要
基于介质上电润湿(electrowetting-on-dielectric,EWOD)技术的数字微流控技术可以对微量液滴进行灵活操作,近年来日益成为微流控领域的研究热点.本文基于开放式数字微流控驱动器的基本原理,旨在提供器件改进的途径,提出了EWOD器件的性能评价与优化方法.设计制造了不同电极形状的EWOD器件,通过实验对比了不同电极结构的性能,分析了EWOD器件性能改善的内在原因.本文提出的开放式数字微流控驱动器设计思路与评价方法可以为EWOD器件以及基于EWOD技术的数字微流控芯片设计起到指导作用.
Due to its ability to manipulate droplets flexibly, electrowetting-on-dielectric （EWOD） based digital microfluidies have been widely researched. This paper focuses on the design principles of improved open EWOD based digital microfluidics actuators. EWOD devices of different electrode formation were fabricated and tested. Based on the analysis and experiments, evaluation methods of open EWOD devices have been presented, which gives guidance to the improvement of EWOD actuators.
