12 Claims

1. A woven article having an electronic function interwoven therein, comprising:

at least one electrically conductive yarn disposed in one of a warp or a weft direction of said woven article, said electrically conductive yarn being suitable for transmitting an electrical current; and

at least one functional yarn disposed in one of said warp or said weft direction of said woven article and crossing said electrically conductive yarn, said functional yarn comprising:

a flexible elongated insulating electronic substrate;

at least two electrical conductors disposed substantially overlying and extending lengthwise along at least a portion of at least one surface of said flexible elongated insulating electronic substrate, said at least two electrical conductors being suitable for transmitting an electrical current, said at least two electrical conductors being strategically positioned to underlie said electrically conductive yarn at their crossing, the at least two electrical conductors being coated with an insulating coating, except at locations where electrical connections are to be made; and

a plurality of electronic devices disposed on and mechanically affixed to said flexible elongated insulating electronic substrate and electrically connected to at least one of said two electrical conductors, said plurality of electronic devices receiving said electrical current transmitted by at least one of said at least two electrical conductors on the functional yarn and said at least one electrically conductive yarn crossing said functional yarn.
