Implementation of Bounded Diffusion Impedance in a Model Pyeis to Correctly Simulate Flow Gradient on Channel-Electrode in Microfluidics

Here, we proposed to test the limits of bounded diffusion impedance model by using electrochemical spectroscopy (EIS) measurements in a microfluidic device architecture bearing set microelectrodes integrated microchannel. This EIS Nyquist plot behaviour was currently modelled with Randles equivalent circuit. In this work, one main advantages for PyEIS (a Python-based Electrochemical Impedance Spectroscopy) software is being able modify and correct models simple implementation source code freely accessible on website author Kristian B. Knudsen. The obtained results after implementing diffusion-convective equation permits adapt each function be plot, simulate fit specific modified channel-electrode. used preliminary tests optimization parameters flow channel comparing layer thickness as volumetric flow.
