Knitted strain sensor

Abstract

Embodiments in this disclosure relate to a knitted strain sensor element comprising an electrically conducting yarn and an elastic yarn. The elastic yarn has a Young's modulus that is substantially lower than the electrically conducting yarn's Young's modulus. The knitted strain sensor element is knitted using a knit stitch pattern comprising knitted stitches and purled stitches on each course. preferably a rib stitch pattern, more preferably a 1×1 rib stitch pattern. The electrically conducting yarn and the elastic yarn are knitted together using a plated knitting technique forming a knitted fabric. the electrically conducting yam forming a core of the knitted fabric and the elastic yarn forming surface of the knitted fabric. Sensors. textiles and garments comprising such knitted strain sensor elements are also disclosed.
