Abstract:

Objective Current research mainly focuses on monitoring human physiological signals or fingers movements that can cause a certain strain under low stress. However, shoulder and neck movement require high stress to cause small strain, which is difficult to be monitored using knitted sensing fabrics. Therefore, the study aimed to develop elastic sensing woven webbing, to investigate its design and fabrication method, and to explore the sensing properties and the application feasibility through corresponding human wearing test.

Method The conductive yarns were used as selvage yarns in elastic web weaving process. Effects of on-machine weft density, elastic yarn fineness and the number of conductive yarns on sensing properties were explored. Three levels of each factor created 27 treatment combinations, leading to 27 elastic woven webbing samples with different tensile properties. The resistances in a certain length of the webbing samples were measured when the elastic webbings were stretched to the same strain. The resistance-strain curve was developed, presenting the sensing curve. Linearity and reproducibility of the sensing property were analyzed after repeated tests. Also, the corresponding equivalent resistance calculation formula was obtained so that to examine the selvedge structure and the sensing mechanism caused by conductive yarns. Finally, the elastic webbing with the best performance was applied in a wearing experiment of human postural hunchback angle monitoring to verify the stability and application possibility of the sensing webbing.

Results The sensing curves of elastic sensing woven webbing demonstrated an increasing trend with ideal linear feature, with high corresponding sensitivity and stable repeatability. The special selvage structure of the elastic woven webbing was found to play an important role in sensing properties. Increasing the on-machine weft density, fineness of elastic yarn, or the number of elastic yarns in the locked selvage enhanced the sensitivity of the sensing elastic webbing. In addition, the human wearing test further verified that the sensing performance of this elastic sensing woven webbing was stable and applicable to monitor human shoulder and neck motion.

Conclusion The study was undertaken to analyze the sensing property and sensing mechanism of the elastic webbing with conductive selvage yarns. The weft density, the fineness and the number of elastic yarns have significant effects on the sensing performance. The corresponding equivalent resistance calculation formula obtained is helpful to analyze the corresponding varying trend of each equivalent resistance unit under the strain. Findings in the study provide an ideal way to monitor human movements with high stress and small strain.
