How to implement electrochemical impedance spectroscopy

When it comes to electrochemical impedance spectroscopy, the right materials are of paramount importance. For those who are not yet familiar with an EIS chip and the mechanisms of electrochemical impedance spectroscopy, it can be said that it is about determining the dielectric properties of a medium and the ratio with the frequency of the medium. An EIS chip is the apparatus pur sang to investigate these attributes of electrochemistry. That is, these kind of chips are specifically produced by relevant companies to allow for the easy and correct interpretation of phenomena related to electrochemical impedance spectroscopy.

The different mechanisms of electrochemical impedance spectroscopy

A medium that is the object of study can interact with a field in multiple ways. These are called the mechanisms and can be objectified by an EIS chip. In summary, the different mechanisms are:

–          Electronic polarization

–          Atomic polarization

–          Dipole relaxation

–          Ionic relaxation

–          Dielectric relaxation

By means of an example, we will discuss electronic polarization. This is in fact a resonant process. That implies that a neutral atom is the object that is changed in this mechanism of electrochemical impedance spectroscopy. As indicated by an EIS chip, we focus now on the neutral atom. What happens is that the electric field that is in place displaces the electron density as seen from the nucleus that it circles around. Of course this sounds very technical, but it is one of the situations in which an understanding of electrochemical impedance spectroscopy and the workings of an EIS chip is crucial.

How the mechanisms work in vivo

An EIS chip can be used to measure the different mechanisms. This allows for a more complete insight into the workings of the body and several phenomena that can be observed.
