Abstract: A method for use in determining the thickness of a layer of interest in a multi-layer structure. A first electrode is positioned in contact with a first surface of the multi-layer structure, and a second electrode is positioned in contact with a second surface of the multi-layer structure. The second surface is substantially opposite the first surface. The first electrode is pressed against the multi-layer structure at a predetermined sampling pressure, and the structure is optionally adjusted to a predetermined sampling temperature. The electrical impedance between the first electrode and the second electrode is measured.
