Electrical Impedance Spectroscopy

What is electrical impedance spectroscopy (EIS)?

There are a lot of different technologies that improve the information that we want to gain about the human body. It is very difficult to determine the right treatment or the right diagnosis. That is why research is being done. To make sure that we can perform the right research, it is important that we have the right tools. Electrical impedance spectroscopy (EIS) is a tool that is used to determine the characteristics of cells and other elements. Electrical impedance spectroscopy (EIS) can be used to determine whether people have healthy cells in their bodies or not. This is very useful when one needs to determine if someone has cancer or another disease or virus. With the right technology we can determine in a fast and simple way if someone is healthy or not. If you need to wait for a long time for the results of a test, someone might get impatient.

Use of electrical impedance spectroscopy (EIS)

Electrical impedance spectroscopy (EIS) can be used for several things:

  • Quality control within the food industry
  • Counting and sorting of cells
  • Blood analysis

These three options are not the only cases that show that electrical impedance spectroscopy (EIS) is a good and many-sided technology. It is important to know that this tool can be used for a lot of different aspects.

Medical research

It is necessary that we perform research. It does not matter in which area we perform research. It is important that this research is qualitatively good. Medical research is one of the research areas that can help the human health. Therefor it is important that we, humans, support this research. On the Internet you can find a lot of information about medical research. Also you can look for different facilities that perform research.

What is Electrical Impedance Spectroscopy (EIS)?

That is a very good question. Let’s start with what we mean by Impedance. Impedance, like resistance, is a way of measuring the ability of an electrical system to resist the electrical current running through it. However, where resistance is typically measured by the well-known Ohm’s Law and thus represents a rather theoretical concept, impedance can be considered the form resistance to electrical current takes in the real world, which is always just slightly more nuanced and complex than pure theory. So what then is Electrical Impedance Spectroscopy (EIS)? Electrical Impedance Spectroscopy (EIS) refers to a way of measuring the electrical impedance of an element in an electronic system by looking at the frequency of an applied electrical current.

Uses for Electrical Impedance Spectroscopy (EIS)

Electrical Impedance Spectroscopy (EIS) van be used in a variety of ways. Since it is a measurement tool, it provides a specific type of information that can be useful in a plethora of different situations, professional environments and for a range of professional applications, as well as in certain fields of research. For example, since electrical impedance of any material is strongly influenced by the composition of said material, Electrical Impedance Spectroscopy (EIS) can be used in medical practices to determine whether certain bodily tissues have in any way changed composition over time. If so, something might be not right.

EIS and cervical cancer detection

Electrical Impedance Spectroscopy (EIS) can be used, for example, to determine whether the tissue of the cervix is healthy, at risk or cancerous. Because of cytological changes, the electrical impedance of unhealthy cervical cells will be lower compared to that of normal or healthy cervical cells. This is just one example in many of the purposes of Electrical Impedance Spectroscopy (EIS).
