Programmable dynamically changing RC model for evaluation of Dynamic EIS methods and instrumentation

The paper concerns the RC equivalent circuit of electrochemical cell with the impedance changed during the experiment. The model was constructed using the digital potentiometers controlled by the microcontroller. This solution allows to control the model impedance by the software means. By creating adequate changes of the impedance spectrum as a time function, the different impedance measurement method can be tested to find out the the limitation of each method as well as to test the instrumentation.
