Abstract (en)

Expansion sensor for measuring expansion of a textile, comprises at least one yarn (12) exhibiting expansibility, where the yarn exhibits at least two electrically conductive layers (30, 32) arranged around a central cylindrical carrier which forms an insulator (20) and extending along a longitudinal direction of the yarn, and the electrically conductive layers are spatially separated and isolated from each other. The conductive layers are opposite to each other extending along the longitudinal direction of the yarn and are separated from each other by intermediate spaces (34). Expansion sensor (10) for measuring expansion of a textile (40), comprises at least one yarn (12) exhibiting expansibility, where the yarn exhibits at least two electrical conductive layers (30, 32) arranged around a central cylindrical carrier which forms an insulator (20) and extending along a longitudinal direction of the yarn, and the electrically conductive layers are spatially separated and isolated from each other. The conductive layers, arranged around the central support, are opposite to each other extending along the longitudinal direction of the yarn and are separated from each other by an intermediate spaces (34) extending along the longitudinal direction of the yarn. Independent claims are also included for: (1) a textile comprising the expansion sensor, which is incorporated preferably by weaving or knitting; and (2) measuring the expansion of the textile, comprising (a) incorporating at least one expandable yarn into the textile, where the yarn exhibits at least two electrical conductive layers arranged around a cylindrical shape central carrier, which forms an insulator and extending along a longitudinal direction of the yarn, preferably extending parallel to each other, and the electrical conductive layers are spatially separated and isolated from each other, and (b) measuring a change in the capacitance of a capacitor formed by the conductive layers or a change in an electrical resistance of a conductor path, formed by the conductive layers, for determining the expansion of the textile.
