Electrochemical Impedance Spectroscopy of protective coatings
Materials and Corrosion, 1985AbstractElectrochemical impedance spectroscopy (EIS) carried out over a wide frequency range (105 to 10−2 Hz) allows us to obtain mechanistic information concerning corrosion protection by coatings. Examples are given for polymer coatings on an Al alloy as a function of surface petreatment and for anodized Al alloys.

The use of electrochemical impedance spectroscopy for biosensing
Analytical and Bioanalytical Chemistry, 2008This review introduces the basic concepts and terms associated with impedance and techniques of measuring impedance. The focus of this review is on the application of this transduction method for sensing purposes. Examples of its use in combination with enzymes, antibodies, DNA and with cells will be described.

Electrochemical impedance spectroscopy of polypyrrole based electrochemical immunosensor
Bioelectrochemistry, 2010Polypyrrole (Ppy) has been shown as a matrix for label-free electrochemical immunosensor based on electrochemical impedance spectroscopy (EIS) measurements. The immunosensing system model presented here was based on bovine leukemia virus (BLV) protein (gp51) entrapped within electrochemically-synthesized polypyrrole (Ppy/gp51).

Electrochemical impedance spectroscopy at an ultramicroelectrode
Journal of Electroanalytical Chemistry, 1994The use of microelectrodes represents one of the most important advances in electrochemistry in the last twenty years: ultramicroelectrodes in particular (the dimensions of which are typically a few micrometers) are now used for a wide range of electrochemical studies [l-6].

Electrochemical Impedance Spectroscopy
2012Electrochemical impedance spectroscopy (EIS) is a method to study the characteristics of organic and inorganic materials, based on their passive electrical properties, determined by the observation of the tissue electrical response to the passage of external electrical energy.

Glucose characterization based on electrochemical impedance spectroscopy
2014 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings, 2014In this paper an equivalent circuit model is employed in the characterization of the impedance measurements of saline solutions at physiological glucose concentrations. The impedance data are obtained using a three electrodes cell configuration since it allows measuring the potential accurately in the working electrode independently from the counter ...

Dynamic Electrochemical Impedance Spectroscopy
ECS Transactions, 2009The hardware and software for a dynamic electrochemical impedance spectroscopy system are described. The applied waveform is a continuous computer-generated multisine waveform added to a potential sweep. A fast potentiostat applies the potential signal and the impedance is derived from the Fourier transforms of the measured current and potential ...

The Advantages and Pitfalls of Electrochemical Impedance Spectroscopy
CORROSION 1989, 1989Abstract The use of electrochemical impedance spectroscopy (EIS) in corrosion research is briefly reviewed with particular emphasis on the advantages offered by this technique over other electrochemical methods. These advantages include the fact that it is a steady state technique, that it employs small signal analysis, and that is ...
