The many purposes Electrical Impedance Spectroscopy (EIS)
Electrical Impedance Spectroscopy (EIS) is a fascinating and powerful method of measuring electrical impedance. Electrical impedance basically refers to how electrical resistance functions in a non-ideal resistor. Ohm’s law, which is a law in theoretical physics that describes resistance, only functions when considering an ideal resistor of electrical current. Since ideal resistors hardly exist in the real world, the concept of electrical impedance is used to describe the more nuanced and complex electrical resistance present in non-homogenous materials, such as body tissue or chemic solutions.
Applications of Electrical Impedance Spectroscopy (EIS)
Since Electrical Impedance Spectroscopy (EIS) can be used to identify specific types of tissue or fluid composition, it can also be used to determine whether something in the studied material has changed, whether its electrical impedance has risen or fallen over the course of a certain period. This can be very helpful for example in medicine and medical practice. Different body tissues give off different readings when studied through Electrical Impedance Spectroscopy (EIS). Through Electrical Impedance Spectroscopy (EIS) the development of a disease that affects bodily tissue – such as cancer – can be screened.
EIS in research and science
Since Electrical Impedance Spectroscopy (EIS) is in the basis a measurement tool, it is obviously also used in science and empirical research, a field in which measurements are crucial in supporting claims of any kind. Electrical Impedance Spectroscopy (EIS) provides data about the studied materials, such as their composition and thickness, that can be analyzed by researchers. As always, it is by doing research using a certain method that the uses and limitations, as well as the advantages and disadvantages of this method can be understood, mapped and put to work in a more applied context, such as medicine or the pharmaceutical industry.
