Electrochemical Impedance Spectroscopy and its Applications | SpringerLink

The application of electrochemical impedance spectroscopy EIS has increased dramatically in the past few years due to its ability to elucidate a plethora of physical and electronic properties of electrochemical systems such as diffusion coefficients, electron transfer rate constants, adsorption mechanisms, charge transfer resistances, capacitances and pore sizes. This review provides a short introduction to the fundamental principles of EIS before exploring the many exciting and pertinent analytical applications regarding the numerous methods in biosensing, the application of EIS with graphene based materials and last, the use of EIS with screen printed electrodes.

Introduction

Electrochemical impedance spectroscopy EIS was used for advanced characterization of organic electroactive compounds along with cyclic voltammetry CV. In the case of fast reversible electrochemical processes, current is predominantly affected by the rate of diffusion, which is the slowest and limiting stage. EIS is a powerful technique that allows separate analysis of stages of charge transfer that have different AC frequency response. The capability of the method was used to extract the value of charge transfer resistance, which characterizes the rate of charge exchange on the electrode-solution interface. The application of this technique is broad, from biochemistry up to organic electronics.
