Abstract

The invention relates to a strain sensor for weft knitted fabric and a knitting method. The sensor comprises a sensing area and connecting areas. The sensing area comprises plain plaiting coils using face yarn as the conductive yarn and using ground yarn as the elastic yarn. The connecting areas are located at two sides of the sensing area. The connecting areas comprise plain plaiting coils using face yarn as the yarn and the ground yarn as the elastic yarn. Edge locking areas are located at the outer sides of corresponding connecting areas. The edge locking areas comprise plain plaiting coils using face yarn as the yarn and the ground yarn as the elastic yarn, wherein, the face yarn is exposed at the front sides of the sensing area, connecting areas and edge locking areas, and the ground yarn is exposed at the back sides of the sensing area, connecting areas and edge locking areas. The conductive yarn in the sensing area is in a bending structure. The sensor has a good extendability and elastic recovery, the equivalent resistance in the curved sensing area is larger than a rectangular area indicating the sensor has a high sensitivity coefficient.

Description

technical field [0001] The invention relates to a weft-knitted fabric strain sensor, in particular to a weft-knitted fabric strain sensor for measuring tensile and bending strains and a weaving method thereof. Background technique [0002] Weft-knitted fabrics have good extensibility and elasticity, and the equivalent resistance of the weft-knitted structure sensor woven with conductive yarn changes when it is stretched, making it a resistive strain sensor, conductive yarn and elastic yarn The combination of the sensor shows excellent reproducibility. [0003] The weft-knitted sensor can be directly woven or integrated on other carriers (such as clothing, gloves, socks, wristbands, etc.) to form a wearable strain sensor. Different wearable methods make it possible to monitor physiological signals and movement conditions of the human body, such as breathing, heartbeat, and joint mobility. [0004] In the prior art, Chinese Patent No. 201220565490.6 discloses a knitted flexi...
