我们介绍了DropBot：一种用于数字微流体的开源仪器（http：//microfluidics.utoronto.ca/dropbot）。DropBot具有数字微流体的两个关键功能：（1）实时监测瞬时液滴速度（我们建议它是电阻力的代理），以及（2）通过补偿电容器负载和设备电容来应用恒定的静电驱动力。我们预计，该系统将提高对故障模式的洞察力，并导致提高设备可靠性的新策略，并将有助于越来越多的用户采用数字微流体技术进行自动化，小型化实验室操作。(C)2013 AIP Publishing LLC.
We introduce DropBot: an open-source instrument for digital microfluidics ( http://microfluidics.utoronto.ca/dropbot). DropBot features two key functionalities for digital microfluidics: (1) real-time monitoring of instantaneous drop velocity (which we propose is a proxy for resistive forces), and (2) application of constant electrostatic driving forces through compensation for amplifier-loading and device capacitance. We anticipate that this system will enhance insight into failure modes and lead to new strategies for improved device reliability, and will be useful for the growing number of users who are adopting digital microfluidics for automated, miniaturized laboratory operation.
