论文摘要
在这里,我们提出了通过在微流体设备架构中使用一组集成在微通道中的微流体架构中的电化学阻抗光谱(EIS)测量来测试有界扩散阻抗模型的极限。目前,这种EIS Nyquist情节行为是用Randles等效电路建模的。在这项工作中,使用PYEI(基于Python的电化学阻抗光谱)的主要优点之一是能够在作者Kristian B. Knudsen网站上免费访问的源代码中的简单实现来修改和纠正模型。在PYEIS代码中实现扩散相关方程后获得的结果允许调整每个函数,以便能够绘制,模拟和拟合特定的修改randles作为通道 - 电信。修改后的兰德尔(Randles)用于初步测试,以优化微流体通道中流量参数,通过比较扩散层厚度作为函数与体积流量。
Here, we proposed to test the limits of the bounded diffusion impedance model by using electrochemical impedance spectroscopy (EIS) measurements in a microfluidic device architecture bearing a set of microelectrodes integrated in microchannel. This EIS Nyquist plot behaviour was currently modelled with the Randles equivalent circuit. In this work, one of the main advantages for using PyEIS (a Python-based Electrochemical Impedance Spectroscopy) software is being able to modify and correct the models with a simple implementation in the source code freely accessible on the website of the author Kristian B. Knudsen. The obtained results after implementing the diffusion-convective equation in the PyEIS code permits to adapt each function to be able to plot, simulate and fit a specific modified Randles for channel-electrode. The modified Randles was used for preliminary tests for optimization of the parameters of flow in the microfluidic channel by comparing the diffusion layer thickness as a function with the volumetric flow.
