Abstract
Metal flakes, an organic metal precursor, an organic solvent and either no binder, or a volatile or a thermally decomposable binder are combined to form a paste. The paste is deposited in a circuit pattern on a substrate and the circuit pattern is cured. While curing, the organic metal precursor decomposes to leave an electrically conductive path, and the printed circuit is thus formed. A precursor to an electrically conductive circuit material includes an organic metal precursor, metal microparticles, and an organic solvent. The method can be employed to form printed circuits, for a variety of electrical, electronic and sensing application, such as crack detection in ceramic, plastics, concrete, wood, fabric, leather, rubber or paper and composite materials.
