✦ Synopsis

Electrochemical impedance spectroscopy (EIS) is a technique that probes energy storage and dissipation properties over a range of frequencies by measuring impedance (the opposition to the flow of alternating current in a complex system). The technique is applicable to almost any physicochemical system, and has been employed in a wide variety of areas such as testing fuel cells, studying biomolecular interactions, microstructural characterization, corrosion studies, biomedical devices, semiconductors, solid-state devices, sensors, batteries, electrochemical capacitors, dielectric measurements, coatings, electrochromic materials, analytical chemistry, imaging, electrochemical cells, mass-beam oscillators, and biological tissues.

Because of its broad applications, the field has been growing tremendously, and the number of articles published has doubled approximately every four or five years. In 2006, more than 1200 papers mentioning its use appeared in journals.
