Physiological sensing textile apparatus

A textile-based garment system, comprising:

• 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, wherein each of the plurality of resistive pressure 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;
• one or more triboelectric sensors coupled to the garment at one or more second specified locations, wherein each of the one or more triboelectric sensors comprises;
• a pair of second textile-based outer layers each having an electrical resistance of no more than 100 ohms, and
• a textile-based triboelectric core sandwiched between the pair of second textile-based outer layers,
• wherein the textile-based triboelectric core comprises a first textile-based dielectric layer and a second textile-based dielectric layer,
• wherein the first textile-based dielectric layer comprises a first textile-based dielectric material that forms a positively-charged triboelectric surface, and
• wherein the second textile-based dielectric layer comprises a second textile-based dielectric material that forms a negatively-charged triboelectric surface, wherein the positively-charged triboelectric surface of the first textile-based dielectric layer is adjacent and proximate to the negatively-charged triboelectric surface of the second textile-based dielectric layer, and
• electronics configured to process signals from the distributed array of resistive pressure sensors and the one or more triboelectric sensors to determine one or more physiological properties of the wearer of the garment substrate.
