    • A compact multiplexed system of electrospraying and a method of fabricating the multiplex system is provided in order to increase by orders of magnitude the liquid flow rate to be dispersed and of retaining the quasi-monodispersity of the generated droplets. The system can be microfabricated as an array of nozzles etched in silicon using a microfabrication technique selected from micro-electro mechanical fabrication techniques and/or micromolding techniques, with a density of 100-2000 sources/cm2. The successful performace of the multiplexed system is critically dependent on a careful selection of the electrode configuration, with entails an extractor electrode mounted at a distance from the nozzle array. The one or more extractor electrodes have the dual function of limiting electric field cross talk between neighboring sources and minimizing space charge feedback from the spray cloud. The system may be optimized to produce uniform droplets simultaneously from all paralleliyed electrosprays, each one operating as an isolated spray in the quasi-monodisperse cone-jet mode.
    • 提供了电喷雾的紧凑多路复用系统和制造多路复用系统的方法,以便增加要分散的液体流速和保持所产生的液滴的准单分散性的数量级。 该系统可以使用选自微电子机械制造技术和/或微成型技术的微加工技术,以100-2000个源/ cm 2的密度,将其作为在硅中蚀刻的喷嘴阵列进行微加工。 多路复用系统的成功执行在很大程度上取决于仔细选择电极配置,需要一个距离喷嘴阵列一定距离的提取器电极。 一个或多个提取器电极具有限制相邻源之间的电场串扰并且最小化来自喷雾的空间电荷反馈的双重功能。 该系统可以被优化以从所有并联电喷雾同时产生均匀的液滴,每个电喷雾以准单分散锥喷射模式中的隔离喷雾操作。
