Short summary
Electrical impedance spectroscopy, in which a sine-wave test voltage or current is applied to the sample under test to measure its impedance over a suitable frequency range, is a powerful technique to investigate the electrical properties of a large variety of materials. This paper presents an updated review of EIS main applications such as measure of bacterial concentration, analysis of human body composition and characterization of food products, as well as other non-biological applications.
