Abstract

An interfacial component detection apparatus has a plurality of electrodes spaced from one another on a first solid portion and a solid electrolytic layer on the first solid portion adjacent to an interfacial layer and covering the plurality of electrodes. An I/O device applies an electrical signal between the two electrodes and detects electrical signals from the electrodes. Components of the interfacial layer can be accurately and reliably detected by electrolysis and impedance measurements.
