Abstract
Abstract A process and apparatus applicable to products which are or can be made electrically conductive for the purpose of measuring information encoded in them as a result of the manufacturing steps employed. Elemental mechanogalvanic potentials reflect a measure of the total information content of a product and are generated when the product serves as an electrode and where a second electrode with a rollable solid electrolyte in contact with the product rolls over it generating data related to the elemental constituents of the product. Mappings or numerical matrices whose elements are the mechanogalvanic potentials can be the basis of extensive important analysis by conventional mathematical procedures.
