Performance analysis of knitted strain sensors based on finite element simulation
摘要
Abstract
In order to gain a better understanding of the effects of different yarn fineness and density on the per-formance of flexible strain sensors,a finite element simulation approach was employed for performance analy-sis.Silver-plated nylon yarn(280 D)was selected to weave 5 cm×10 cm plain weft fabrics using 1-ply,2-ply,and 3-ply yarns.Tensile tests were conducted on the fabrics under strain ranging from 0%to 60%.The geomet-ric parameters of the fabric loops were measured using a microscope,and a geometric model of the fabric was constructed in Rhino.Finite element simulations were performed using COMSOL to model the fabric's tensile strain process from 0%to 60%.The results indicated that with the increase in the number of strands,the peak re-sistance rose,and the fluctuation in the resistance variation rate became more pronounced.Furthermore,a com-parison between finite element simulations and experimental results revealed that the average error did not ex-ceed 3%,and the maximum error did not exceed 9%,which confirmed the feasibility and accuracy of the finite element simulation method for performance analysis.关键词
