Abstract
A printed electronic tag (2) for packaging comprising a first set of spaced, electrically-conductive lines (4) overlying a substrate (5), an electrically-insulating layer (6) overlying at least a portion of the first set of lines, a second set of spaced, electrically-conductive lines (8) overlying the insulating layer, arranged to cross the first set of lines, the insulating layer configured to provide at least one region (10) for providing electrical contact between a line in the first set of the conductive lines and a line in the second set of lines.
Claims24
An electronic tag comprising:
- an electrically-insulating substrate comprising a consumer product, packaging for a product or printed material,
- a first set of independent and spaced electrically-conductive lines comprising electrically-conductive ink printed on a face of the electrically-insulating substrate,
- an electrically-insulating layer printed on at least a portion of the first set of lines and the face of the substrate, and
- a second set of independent and spaced electrically-conductive lines comprising electrically-conductive ink printed on the insulating layer, the first set of lines and the face of the substrate and arranged to cross the first set of lines transversely,
- wherein the electrically-insulating layer is configured to provide at least one region of electrical insulation between at least one line in the first set of conductive lines and at least one line in the second set of lines and to provide at least one region of electrical contact between at least one line in the first set of the conductive lines and at least one line in the second set of lines.
A method of printing comprising:
- providing an electrically-insulating substrate comprising a consumer product, packaging for a product or printed material;
- printing a first set of independent and spaced electrically-conductive lines comprising electrically-conductive ink on a face of the electrically-conductive substrate;
- printing an electrically-insulating layer on at least a portion of the first set of lines and the face of the substrate;
- and
- printing a second set of independent and spaced electrically-conductive lines comprising electrically-conductive ink on the insulating layer, the first set of lines and the face of the substrate and arranged to cross the first set of lines transversely,
- wherein the electrically-insulating layer is configured to provide at least one region of electrical insulation between at least one line in the first set of conductive lines and at least one line in the second set of lines and to provide at least one region of electrical contact between at least one line in the first set of the conductive lines and at least one line in the second set of lines.
A method of reading an electronic tag comprising an electrically-insulating substrate comprising a consumer product, packaging for a product or printed material, a first set of independent and spaced electrically-conductive lines comprising electrically-conductive ink printed on a face of the electrically-insulating substrate, an electrically-insulating layer printed on at least a portion of the first set of lines and the face of the substrate, and a second set of independent and spaced electrically-conductive lines comprising electrically-conductive ink printed on the insulating layer, the first set of lines and the face of the substrate and arranged to cross the first set of lines transversely, wherein the electrically-insulating layer is configured to provide at least one region of electrical insulation between at least one line in the first set of conductive lines and at least one line in the second set of lines and to provide at least one region of electrical contact between at least one line in the first set of the conductive lines and at least one line in the second set of lines, the method comprising:
- capacitively probing lines in the tag.
