Applying microfluidic patterning, droplets were precisely generated on an electrowetting-on-dielectric (EWOD) chip considering these parameters: number of generating electrodes, number of cutting electrodes, voltage, frequency and gap between upper and lower plates of the electrode array on the EWOD chip. In a subsequent patterning experiment, an environment with three generating electrodes, one cutting electrode and a gap height 10 μm, we obtained a quantitative volume for patterning. Propylene carbonate liquid and a mixed colloid of polyphthalate carbonate (PPC) and photosensitive polymer material were manipulated into varied patterns. With support from a Z-axis lifting platform and a UV lamp, a cured 3D structure was stacked. Using an EWOD system, a multi-layer three-dimensional structure was produced for the patterning. A two-plate EWOD system patterned propylene carbonate in a quantitative volume at 140 Vpp/20 kHz with automatic patterning.

使用微流体 EWOD 和 DEP 设备在定量体积中进行图案化和建模的虚拟模板


应用微流控图案化，在电介质电润湿 (EWOD) 芯片上精确生成液滴，考虑以下参数：发生电极数量、切割电极数量、电压、频率以及 EWOD 上电极阵列上下板之间的间隙芯片。在随后的构图实验中，在3个发生电极、1个切割电极、间隙高度10μm的环境下，我们获得了用于构图的定量体积。碳酸丙烯酯液体以及聚邻苯二甲酸酯碳酸酯（PPC）和光敏聚合物材料的混合胶体被操纵成不同的图案。在 Z 轴升降平台和 UV 灯的支撑下，堆叠了固化的 3D 结构。使用 EWOD 系统，生成了用于图案化的多层三维结构。两板 EWOD 系统以 140 Vpp/20 kHz 的定量体积对碳酸丙烯酯进行自动图案化图案化。
