This work reports the engineering of textile electrodes, considered safe for humans even if worn next to skin for a longer time. Obliging this phenomenon conductive Silver nanoparticles (AgNPs) were biosynthesized from Silver Sulphate (Ag2SO4) and medicinal values enriched Ocimum Sanctum (Tulsi)leaves extract. These conductive Silver nanoparticles were loaded by spray technique on polypropylene nonwoven fabric having inbuilt antifungal characteristics, to reduce its resistivity (10Ω) for the fabrication of textile electrodes. The adequate skin-electrode impedance values were observed for the fabricated textile electrodes, viz; 1.44 MΩ–1.83 MΩ and 1.01 MΩ–1.18 MΩ, in the dry and wet state respectively. The 3-lead health monitoring electrocardiograms (ECG) were obtained on the Analogous system with the textile electrodes; dry and wet state as well as gel electrodes. The cardiograms were also taken at a smaller triangle than usual, only for the high resistance textile electrodes. The wet electrodes have executed considerably better clarity of PQR wavelets than reference gel electrodes ECG plots, and their performance was found consistent when tested after six months’ time leap. However, higher motion artifacts caused in the case of dry electrodes have resulted in distorted PQR wavelets and the tracing became worsen with increased testing time leap. This was mainly due to the encapsulation of conductive AgNPs in the air voids of the fabric, increased resistivity. The cardiogram quality has not shown peculiar benefit for a higher heart pumping pressure at the smaller triangle in either of the cases.

生物合成银纳米粒子负载聚丙烯无纺布纺织电极的测量性能,用于类似系统上的 3 导联健康监测心电图

这项工作报告了纺织电极的工程,即使长时间贴在皮肤上,它也被认为对人类是安全的。迫使这种现象导电银纳米粒子 (AgNPs) 从硫酸银 (Ag 2 SO 4 ) 和药用价值丰富的Ocimum Sanctum (Tulsi)生物合成叶提取物。这些导电银纳米粒子通过喷涂技术加载到具有内置抗真菌特性的聚丙烯无纺布上,以降低其电阻率(10Ω),用于制造纺织电极。对于制造的纺织电极,观察到足够的皮肤电极阻抗值,即;干态和湿态分别为 1.44 MΩ–1.83 MΩ 和 1.01 MΩ–1.18 MΩ。3 导联健康监测心电图 (ECG) 是在具有纺织电极的类似系统上获得的;干湿状态以及凝胶电极。心电图也是在比平时更小的三角形处拍摄的,仅适用于高电阻纺织电极。湿电极比参考凝胶电极心电图执行的 PQR 小波清晰度要好得多,在经过六个月的时间跳跃后测试时发现它们的性能是一致的。然而,在干电极的情况下引起的更高的运动伪影导致 PQR 小波失真,并且随着测试时间的增加,跟踪变得更糟。这主要是由于导电 AgNPs 封装在织物的空隙中,增加了电阻率。在任何一种情况下,心电图质量都没有显示出较小三角形处较高的心脏泵血压力的特殊好处。
