包覆方法对可拉伸温度传感混合电子纱性能的影响

Effect of packaging methods on the properties of stretchable temperature sensing hybrid electronic yarn

通过传统电子封装技术制备的温度传感混合电子纱柔软性差,难以制成可穿戴设备用于人体健康检测。分别采用包缠与编织2种方法对可拉伸温度传感混合电子纱进行包覆,探讨包缠层数和编织角对传感区域直径和纱线伸长率的影响,并测试2种包覆传感纱的传感性能和循环拉伸性能。结果表明,包缠层数对纱线伸长率的影响较大,随着包缠层数增加,纱线的伸长率减小;编织角对传感区域直径和纱线伸长率均有显著影响,随着编织角减小,两者均减小;包覆及包覆方法均对传感纱的灵敏度无显著影响,但对响应时间有影响;循环拉伸对2种包覆传感纱的传感性能影响较小。

Temperature sensing hybrid electronic yarn prepared by traditional electronic packaging technology has poor softness,and it is difficult to be made into wearable devices for human health detection.Wrapping and braiding methods were used to package the hybrid electronic sensing yarn stretchable temperature sensing hybrid electronic yarn,and the effects of the number of packaging warpping layers and the braiding angle on the diameter of the sensing area and the elongation of yarns were explored.Then,the sensing performance and cyclic tensile properties of these two coated packaged sensing yarns were tested.The results show that the number of packaging warpping layers has a greater effect on the yarn elongation,and the yarn elongation decreases with the increase of the number of packaging warpping layers;the braiding angle has a significant effect on the diameter of the sensing area and the elongation of the yarn,both of which decrease with the decrease of the braiding angle;the packaging procedure and packaging methods have no significant effect on the sensitivity of the sensing yarns,but have an effect on the response time;cyclic tensile has little effect on the sensing performance of the two packaged sensing yarns.
