基于心電信號的織物電極研究

基于心電信號的織物電極研究摘要：

近年來，隨著健康意識的提高和人口老齡化的加劇，心腦血管疾病已成為全球范圍內(nèi)的頭號殺手。心電信號的檢測是對心臟病診治、預防和管理的必要手段之一，而傳統(tǒng)的心電信號檢測需要使用黏貼電極或插入式電極等接觸性電極，不僅不便于使用，而且易帶來不適和痛感，因此本文提出了一種基于織物電極的心電信號檢測方法。

本文使用了織物材料作為電極載體，并采用導電纖維作為導電材料，將其結(jié)合在一起制成了織物電極。首先，我們對織物電極的材料、形狀、導電性能等進行了研究和優(yōu)化；其次，我們對織物電極與傳統(tǒng)接觸性電極的信號質(zhì)量進行了比較，證明了織物電極在信號質(zhì)量上優(yōu)于傳統(tǒng)接觸性電極；最后，我們進行了實驗驗證，結(jié)果表明，自行研制的織物電極可以有效地采集心電信號，并能夠達到臨床使用的標準。
