Abstract

A stereoscopic conductive fabric includes a basement yarn layer, a conductive yarn, and a support yarn. The basement yarn layer includes plural warp yarns arranged coursewise and parallel to each other and plural course yarns arranged warpwise and parallel to each other. The course yarns are interwoven with the warp yarns to form the basement yarn layer. The conductive yarn is arranged coursewise and interwoven with the course yarns in a skip manner to form plural conductive structures protruding from a surface of the basement yarn layer. The support yarn is arranged coursewise and interwoven with the course yarns in a skip manner to form plural pressing structures protruding from another surface of the basement yarn layer. A module for detecting electrical signals from body skin applying the stereoscopic conductive fabric is also disclosed.
