Estimating the term…
Manufacturing techniques are described for forming electrical components. For example, a layer of a metal powder composition is deposited onto at least a portion of a substrate. Pressure is applied to the metal powder composition by hydraulic press that has one or more projections in order to capture a pattern on the substrate. The metal powder composition compressed by the projections of the hydraulic press adhere to the substrate to form the captured pattern. The metal powder composition in regions not compressed by the projections of hydraulic press do not adhere to the substrate and may be removed. The metal powder composition may be compressed to form electrical components, such as antennae, capacitor plates, conduction pads and the like, for use in an electronic surveillance system (EAS), a radio frequency identification (RFID) system, or the like.
An article comprising a conductive pattern on a substrate that forms an electrical component of an electromagnetic communication circuit, wherein the conductive pattern comprises a densified metal powder composition compressed into at least a portion of the substrate, and wherein the substrate is selected from a group consisting of paper and materials that are at least about 10% compressible.
An article comprising:
An article comprising a conductive pattern on a substrate, wherein the conductive pattern forms all or part of one or more electrical components, wherein the conductive pattern consists essentially of a densified metal powder composition, and wherein the substrate is selected from the group consisting of paper and materials that are at least about 10% compressible.
An article comprising a conductive pattern on a substrate, wherein the conductive pattern forms all or part of one or more electrical components, wherein the conductive pattern consists essentially of a densified metal powder composition, wherein the substrate is selected from the group consisting of paper and materials that are at least about 10% compressible, and wherein the article further comprises at least one component that is not formed by a conductive pattern consisting essentially of a densified metal powder.
