What can we learn from Impedance Spectroscopy?
Original language description
Measurement of electrical impedance is a kind of an instrumental method. Over years, with advances of electronics and instrumentation in general, the technique is often available through commercial instruments or add-on modules to such commercial instruments. Impedance, in its simplest form, is an electrical method in which generalized resistance of material to flow of alternating current is measured. The frequency of the applied signal is varied over a wide range, thus the term "spectroscopy" in this method. In the measurement both the ratio of the applied potential and the resulting current, as well as the phase shift between the imposed potential and the resulting current, are measured. Thus, a two parameter result is obtained for each frequency of the applied AC signal. The method, with appropriate mathematical treatment, allows study of materials through evaluation of the two component result - the impedance response - on the applied frequency.
