Abstract
Electrical impedance spectroscopy (dielectric or electrochemical impedance spectroscopy) is a widespread characterization method for solids or fluids in industrial applications. Here we present a novel combination of the electrical impedance spectroscopy with its thermal equivalent, that we thus call “thermal impedance spectroscopy”. With this combination, a deeper insight of the fluid properties, especially at different fluid mixtures, is possible.
