Abstract
A woven article having plural weave layers comprises a plurality of electrically insulating and/or electrically conductive yarn in the warp and a plurality of electrically insulating and/or electrically conductive yarn in the weft interwoven with the yarn in the warp. An electrical function is provided by one or more circuit carriers disposed in cavities in the plural layer woven article and/or one or more functional yarn in the warp and/or the weft, wherein the circuit carrier and/or functional yarn include an electrical contact for connecting to the electrically conductive yarn in the warp and/or weft.
Claims10
A multilayer woven article having a warp and a weft, and defining an electrical circuit, said multilayer woven article comprising:
- a plurality of electrically insulating yarns and uninsulated electrically conductive yarns in the warp;
- a plurality of electrically insulating yarns and uninsulated electrically conductive yarns in the weft interwoven with said plurality of electrically insulating yarns and uninsulated electrically conductive yarns in the warp in a weave defining plural layers of said woven article;
- wherein an uninsulated electrically conductive yarn in the warp crossing an uninsulated electrically conductive yarn in the weft makes electrical connection therewith at the crossing thereof;
- and
- at least one uninsulated electrically conductive yarn in the warp and/or in the weft woven into at least a first layer and a second layer of the plural layers for crossing at least one uninsulated electrically conductive yarn in the other of the warp and/or weft without making electrical contact therewith;
- whereby a multilayer woven article is provided wherein uninsulated electrically conductive yarn disposed in the warp and weft are woven so as to connect at certain crossings when in the same one of the plural layers and to not connect at other crossings when not in the same one of the plural layers to define an electrical circuit.
A method for weaving a fabric and/or a textile electrical circuit article having a warp and a weft comprising:
- providing a plurality of electrically insulating yarns and uninsulated electrically conductive yarns in the warp;
- weaving a plurality of electrically insulating yarns, and uninsulated electrically conductive yarns in the weft with said plurality of electrically insulating yarns and uninsulated electrically conductive yarns in the warp;
- wherein said weaving defines plural layers of the electrical circuit article;
- wherein an uninsulated electrically conductive yarn in the warp crossing an uninsulated electrically conductive yarns in the weft in the same layer of the plural layers makes electrical connection therewith at the crossing thereof;
- and
- weaving at least one uninsulated electrically conductive yarn in the warp and/or in the weft into at least a first layer and a second layer of the plural layers for crossing at least one uninsulated electrically conductive yarn in the other of the warp and/or well without making electrical contact therewith;
- whereby a woven electrical circuit article is provided wherein electrically conductive yarn disposed in the warp and the weft are woven so as to connect at certain crossings when in the same one of the plural layers and to not connect at other crossings when not in the same one of the plural layers.
