Design and performance of knitted structure temperature sensor
Given at the problems of poor wearing comfort and low sensing uniformity of wearable temperature sensors,a soft and breathable knitted structure sensor was designed to measure the surface temperature of human skin.Three factors of fabric structure,plating density and number of plating rows were selected.Each factor was designed as weft plain,1+1 rib,2+1 rib,full needle rib,full plating,1 interval 1 plating,1 interval 3 plating,6,12,18,24,30 plating rows to design orthogonal test.25 kinds of knitted structure sensors were designed and woven by using jacquard yarn-adding weaving technology.The change of fabric resistance during temperature change was tested.The linearity and sensitivity of the samples were analyzed by multi-index range method.The results show that the number of plating rows and fabric structure has the greatest influence on the linearity and sensitivity of the sensor,respectively.Therefore,the func-tional models of linearity and plating rows,sensitivity and fabric structure are obtained.The best combination of fabric parameters is 1+1 rib weave,1+3 plating,and 30 rows of plating.
