Abstract

Textile triboelectric nanogenerators for human respiratory monitoring with machine washability are developed through loom weaving of Cu-PET and PI-Cu-PET yarns. Triboelectric charges are generated at the yarn crisscross intersections to achieve a maximum short circuit current density of 15.50 mA m^-2 . By integrating into a chest strap, human respiratory rate and depth can be monitored.

Keywords: loom weaving; machine-washable; respiratory monitoring; textile triboelectric nanogenerator; wearable technology.
