Abstract
A method and integrated probe for non-contact measuring electrical conductivity of polymer electrolyte films includes placing the film on a flat dielectric substrate, exciting a probing eddy-current magnetic field using an inductance coil at a series of discrete frequencies, and measuring its impedance at these frequencies while the operating end face of the coil is located on the film surface and on the substrate.
