הרקע לפרויקט:

Electrochemical Impedance Spectroscopy (EIS) can provide detailed information regarding biochemical processes and electrolyte composition.

The EIS can provide insights about solution composition or the nature of the grafting or plated material on the electrodes [1].

The EIS can also be used in synthetic biology-based sensors [2]

A setup of 2,3,4 electrode setup [1,3] can be used for obtaining the measurements for a specific challenging problem. The advantages and the disadvantages of each strategy will be evaluated.

The PalmSens [4] commercial potentiostat system and the screen printed electrodes will be used as a baseline system for designing lower cost solution EIS setup which will be characterized and tested in this project.

This project is a collaboration with Prof. Drazen Jurisic (https://www.fer.unizg.hr/en/drazen.jurisic ) from Department of electronics in Zagreb University (he is an expert in analog circuits).

מטרת הפרויקט:

This project is about understanding electrochemical impedance spectroscopy (EIS) and exploring potential applications for EIS

תכולת הפרויקט:

In this multi-disciplinary project, the student will learn how Electrochemical Impedance Spectroscopy can be used for material characterization. The project includes integration of analog and digital circuitry with wet biochemical material (optional).
