A textile-based hydrogel electrode comprises a textile-based backing layer, a conductive structure coupled to the textile-based backing layer, and a hydrogel body in contact with at least a first portion of the conductive structure, wherein the first portion of the conductive structure and the hydrogel body form an ionic interface configured to generate an electrical signal through the conductive structure corresponding to a biopotential change proximate to the textile-based hydrogel electrode.

A garment system comprises a garment substrate formed from one or more textile-based sheets, a distributed array of a plurality of resistive pressure sensors coupled to the garment substrate at a set of first specified locations. Each of the plurality of resistive sensors comprises a pair of first textile-based outer layers each having an electrical resistance of no more than 100 ohms and a textile-based inner layer sandwiched between the pair of first textile-based outer layers having an electrical resistance of at least 1 mega-ohm. The system also includes electronics configured to process signals from the distributed array of resistive pressure sensors to determine one or more physiological properties of a wearer of the garment substrate.

A heating element composite comprises a substrate of one or more fibers or threads and an electrically-conductive polymer coating comprising an electrically-conductive polymer material deposited onto the one or more fibers or threads. A thickness of the electrically-conductive polymer coating is at least about 100 nanometers and the electrically-conductive polymer coating covers at least about 75% of an external surface area of the one or more fibers or threads of the substrate. The resulting heating element composite has a sheet resistance of from about 2&#x3a9;/&#x25a1; to about 200&#x3a9;/&#x25a1;.
