Sewn textile electrodes demonstrated no statistically significant difference compared to traditional gel electrodes in measuring R-R interval (p>0.1), average heart rate (p>0.5), and comfort (p>0.5).
Cross-Sectional (n=8)
Do sewn textile electrodes provide comparable ECG data quality and comfort compared to traditional gel electrodes in human subjects?
Sewn textile electrodes provide comparable ECG data quality and comfort to traditional gel electrodes, demonstrating feasibility for wearable health monitoring.
p-value: p=>0.1 for R-R interval; >0.5 for HR and comfort
Wearable health-monitoring systems should be comfortable, non-stigmatizing, and able to achieve high data quality. Smart textiles with electronic elements integrated directly into fabrics offer a way to embed sensors into clothing seamlessly to serve these purposes. In this work, we demonstrate the feasibility of electrocardiogram (ECG) monitoring with sewn textile electrodes instead of traditional gel electrodes in a 3-lead, chest-mounted configuration. The textile electrodes are sewn with silver-coated thread in an overlapping zig zag pattern into an inextensible fabric. Sensor validation included ECG monitoring and comfort surveys with human subjects, stretch testing, and wash cycling. The electrodes were tested with the BIOPAC MP160 ECG data acquisition module. Sensors were placed on 8 subjects (5 males and 3 females) with double-sided tape. To detect differences in R peak detectability between traditional and sewn sensors, effect size was set at 10% of a sample mean for heart rate (HR) and R-R interval. Paired student’s t-tests were run between adhesive and sewn electrode data for R-R interval and average HR, and a Wilcoxon signed-rank test was run for comfort. No statistically significant difference was found between the traditional and textile electrodes (R-R interval: t = 1.43, p > 0.1; HR: t = −0.70, p > 0.5; comfort: V = 15, p > 0.5).
Arquilla et al. (Thu,) reported a cross-sectional. Sewn textile electrodes vs. Traditional gel electrodes was evaluated on R-R interval, average heart rate, and comfort (p=>0.1 for R-R interval; >0.5 for HR and comfort). Sewn textile electrodes demonstrated no statistically significant difference compared to traditional gel electrodes in measuring R-R interval (p>0.1), average heart rate (p>0.5), and comfort (p>0.5).
