采用一系列与统计方法相关的信号质量指标（SQIs）来指导针织物心电图记录电极的优化过程。从完全针织服装的角度评价电极的结构和组成以及它们在服装中的集成。仅使用具有紧密编织结构和中等粗糙度的导电纱即可获得具有最佳SQIs的干电极。仅在电子服装的边缘处缝制电极即可获得电子服装的最佳质量指数。这种方法优于嵌套和双重编织方法，因为它允许衣服独立于电极运动，减少运动伪影。在健康志愿者身上进行的测试显示，在温和的行走下，系统表现出色。在干法ECG电极优化过程中使用SQIs的优点是，它提供了一个定量基准，与其他方法进行比较。全针织服装允许更轻松的电子服装时，温和的走动是考虑。
A wide range of signal quality indices (SQIs) related to statistical methods are used to guide the optimization process of knitted textile electrodes for electrocardiogram (ECG) recordings. The electrode structure and composition as well as their integration into a garment are evaluated in view of a fully knitted garment. The dry electrodes with the best SQIs are obtained by using conductive yarn only with a compact knit structure and a medium level of roughness. The best SQIs for the e-garment were obtained by sewing electrodes at their edges only, into the knitted garment. This implementation outperforms the intarsia and double-knit method as it allows the garment some independent movement from the electrodes, reducing motion artifacts. Tests done on a healthy volunteer demonstrate excellent system performance under gentle ambulation. The advantage of using SQIs in the optimization process of dry textile ECG electrodes is that they offer a quantitative benchmark against which to compare other approaches. The fully knitted clothing allows for more relaxed e-garments when gentle ambulation is considered.
