Patent ID: 7191803

Claim:
An elastic multi-ply woven fabric stretchable from a retracted position into a plurality of elongated positions for use in a physiological sensing system comprising: a plurality of upper and lower elastic warp yarns arranged in vertically spaced positions forming a plurality of longitudinally extending groups of laterally spaced warp yarns; a plurality of picks of inelastic weft yarn, first ones of said picks weaving with said upper and lower warp yarns forming upper and lower outer surfaces of cells; a conductive warp yarn extending longitudinally of said fabric in controlled sinusoidal configurations in each of said cells; second ones of said picks weaving with said conductive warp yarns between said upper and lower outer surfaces positioning each said conductive yarn in a sinusoidal configuration of said controlled sinusoidal configurations; wherein, said fabric may be extended longitudinally by about 25% from its said retracted position into various of said elongated positions causing said controlled sinusoidal configurations of said conductive yarns to be altered consistent with the degree of said extension.
