面料弹性回复率与心电监测服模型基线不稳伪差关系研究

Study of Research on the Relationship Between Fabric Elastic Recovery Rate and Baseline Unstable Artifacts of ECG Monitoring Clothing Model

为了确定制作心电监测服时是否应该考虑针织面料的弹性回复率值,将制作的6个服装模型各采集10次心电图,并将心电电极片采集电信号产生基线不稳伪差程度分为轻微、一般、较严重、严重、强烈五个等级。发现不同弹性回复率面料制作的心电监测服模型所产生的基线不稳伪差程度有显著性差异,即弹性回复率对采集心电信号有很大影响。

In order to determine whether the selection of suitable elastic recovery rate value of knitted fabric should be paid attention to when making ECG monitoring clothing.ECG was collected 10 times in each of the 6 models,60 times in total.Then,the degree of the base-line instability spurious error produced by the ECG electrode chip is divided into five grades:slight,general,less serious,serious and strong.The results show that the degree of baseline instability pseudo-error produced by ECG monitoring clothing models made of different elastic recovery rate fabrics is significantly different,therefore,the elastic recovery rate has a great impact on the acquisition of ECG signals.
