1. A textile fabric comprising:
a first set of electrically conductive, externally electrically isolated yarns (22) separated by isolating textile yarns (24);
a second set of conductive yarns (23) wherein the first set of electrically conductive, externally electrically isolated yarns (22) and the second set of conductive yarns (23) form a single textile layer (20) and are oriented in the same direction;
a plurality of textile yarns interlacing the first and the second set sets of yarns (22, 23), wherein part of the interlacing textile yarns are interlacing non-isolated conductive yarns (23) that form an electrical grounding grid with the conductive yarns (23) of the second set of yarns and part of the interlacing textile yarns are interlacing isolating textile yarns (24),
wherein the electrical grounding grid operates as a barrier to damp parasitic capacitance between a body portion of a wearer of the fabric and said grid such that a finger touch is detectable and the electrically conductive, externally electrically isolated yarns (22) have isolating external surfaces (27) that electrically isolate the electrically conductive, externally electrically isolated yarns (22).
