About the project

CiecEIS is designed for Electrochemical Impedance Spectroscopy (EIS) research. It allows user to quickly select data, simultaneously fit multiple circumferences using the least squares method, and extract pertinent parameters such as center coordinates, radius, and intersection points with the real axis. It also uses impedance.py library for equivalent circuit fitting.

To enhance fitting accuracy in the presence of significant noise, several data 'cleaning' methods have been implemented.

This tool can be useful in EIS-related fields. Circumference fitting can provide points for initial guess for your custom circuit models and with a circuit fitting script you can try it out on the spot.

Main libraries

Setup

1. Copy repository

   git clone https://github.com/kitkot2/CircEIS.git

   or download .zip file
2. Make shure you have python and pip installed
3. Using command line change directory to CircEIS

   cd path_to_the_project/

4. To install all required libraries for windows:

   pip install -r requirements.txt

   for mac:

   pip3 install -r requirements.txt

5. After installation, run main.py using command line or compiler
