我们建立了一个由通孔、绕行通道和推升式微阀组成的流体电流源的理论模型。该模型准确地描述了这种类型的设备的非线性行为,这是以前的实验测量。我们展示了器件的各种结构参数和材料特性如何影响饱和流速和器件作为电流源所需的最小驱动压力。反过来,该模型可用于设计具有所需饱和流量和低工作压力的流体电流源。该模型可直接应用于由许多功能自调节装置组成的微流控电路。
We develop a theoretical model for a fluidic current source consisting of a via, a detour channel, and a push-up type micro-valve. The model accurately describes the non-linear behaviour of this type of device, which has been previously measured experimentally. We show how various structural parameters and material properties of the device influence the saturated flow rate and the minimum driving pressure required for the device to function as a current source. Conversely, the model can be used to design a fluidic current source with a desired saturated flow rate and low operational pressure. The present model can be straightforwardly applied to microfluidic circuits composed of many functional autoregulatory devices.
