Micromixers are critical components in the lab-on-a-chip or micro total analysis systems technology found in micro-electro-mechanical systems. In general, the mixing performance of the micromixers is determined by characterising the mixing time of a system, for example the time or number of circulations and vibrations guided by tracers (i.e., fluorescent dyes). Our previous study showed that the mixing performance could be detected solely from the electrical measurement. In this paper, we employ electromagnetic micromixers to investigate the correlation between electrical and mechanical behaviours in the mixer system. This work contemplates the “anti-reciprocity” concept by providing a theoretical insight into the measurement of the mixer system; the work explains the data interdependence between the electrical point impedance (voltage per unit current) and the mechanical velocity. This study puts the electromagnetic micromixer theory on a firm theoretical and empirical basis.

了解电磁微混合器中机械速度和电压之间的相互依赖性。

微型混合器是微机电系统中的芯片实验室或微型总体分析系统技术中的关键组件。通常，微混合器的混合性能是通过表征系统的混合时间来确定的，例如由示踪剂（即荧光染料）引导的循环或振动的时间或次数。我们以前的研究表明，仅从电气测量中即可检测到混合性能。在本文中，我们使用电磁微型混合器来研究混合器系统中电气和机械行为之间的相关性。这项工作通过提供对混频器系统测量的理论见解，构想了“反互惠”概念。这项工作解释了电点阻抗（每单位电流的电压）和机械速度之间的数据相互依赖性。本研究将电磁微混合器理论置于牢固的理论和经验基础上。
