What is Electrical Impedance Spectroscopy (EIS)?

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).

Implementing a droplet generator into your experimental set up

As a droplet generator manufacturer, it is well known that it can be hard at first to implement a droplet generator in the paradigm of your experimental research set up. That is, there are two core elements that can lead to difficulty:

  • Firstly, the practical aspect. It can be hard to actually connect a droplet generator and feed it the exact current that it requires. Furthermore, it can be a hassle to handle the tiny device without damaging it.
  • Secondly, the theoretical aspect. A droplet generator manufacturer has often asked itself the question: “What does one need a droplet generator for, i.e. how can one implement it into a research paradigm?”

The practical aspect of a droplet generator

As a droplet generator manufacturer, the greatest care has been taken to make a droplet generator easy to use. The diodes can be identified by their respective looks, it is clear what current should be used and there is an inclusive manual available. The droplet generator manufacturer thus takes care to allow the client to use the droplet generator with ease.

And finally the theoretical side

As a droplet generator manufacturer, it is also well known that some do not know what to use the apparatus for specifically. In order to inspire, a few examples will be offered. One can, for instance, use the current model to create water droplets in an otherwise dry atmosphere and study the effects of that. Furthermore, it would be possible to put the apparatus in a piece of tissue and produce liquids at a certain interval. Thirdly, one could also think of a research setting in which it is of paramount importance to keep a sample uncontaminated. Creating a pure liquid can then be important.
