Abstract

A system of fibers, filaments, and/or other electrically conductive materials forms an electrically conductive-to-semi-conductive yarn that can be assembled into a textile for measurement of voltage, current, resistance, capacitance, inductance, RF, and/or EM signals. Textiles are formed through weaving, knitting, lacing, and/or non-woven mechanical methods of yarn-making into 2D/3D structures. Textile-based electrodes can be formed via folding, cutting, layering, sewing, and/or embroidering patterns to control signal transmission within/through the electrode. Multiple electrodes are positioned on a surface (e.g., a body) to sequentially or simultaneously perform multiple diagnostic modalities (e.g., electrocardiography, electromyography, electrooculography, electroencephalogram, bioelectrical impedance analysis, skin impedance analysis, and/or electrodermal activity). These modalities are multiplexed using an optimized electrode set through amplitude and frequency deconvolution and filtering algorithms to minimize the quantity of electrodes and connections on the surface while maximizing signal-to-noise ratio, differential and common mode noise rejection, and elimination of external signals (e.g., RF and EM noise).
