Description

the method builds on the advantages of a powerful existing technology known as electrochemical impedance spectroscopy (EIS). Here, an AC voltage is applied to an electrode and the current response is measured as a change in impedance. (Impedance is defined as opposition to alternating current and extends the idea of electrical resistance to AC circuits.)
