在这项研究中，描述了与无线心电系统集成的聚合物电极的概念。通过在聚二甲基硅氧烷中负载高含量的碳纳米管，制备了用于长期心电测量的聚合物电极。添加银纳米颗粒(Ag NPs)以增加聚合物的柔韧性和电极的导电性。将电极与粘结性聚二甲基硅氧烷(APDMS)层结合，制成心电电极贴片。填充了PDMS的电极上的孔可以实现电极与皮肤之间的牢固接触，减少运动伪影。研制了一种适用于聚合物电极的无线心电测量系统。将聚合物电极与测量系统相结合，成功地应用于心电信号的无线、长期记录。11天的连续测试表明，心电信号没有随着时间的推移而退化。附加/分离测试的结果表明，在六个附加/分离周期后，心电信号受到运动伪影的影响。制作的电极柔性好，心电性能良好，可用于可穿戴式医疗监护系统。这项研究中提出的方法在医学领域具有重要的商业应用前景。
In this study, the concept of polymer electrodes integrated with a wireless electrocardiogram (ECG) system was described. Polymer electrodes for long-term ECG measurements were fabricated by loading high content of carbon nanotubes (CNTs) in polydimethylsiloxane. Silver nanoparticles (Ag NPs) were added to increase the flexibility of the polymer and the conductivity of the electrode. An ECG electrode patch was fabricated by integrating the electrodes with an adhesive polydimethylsiloxane (aPDMS) layer. Holes in the electrode filled with aPDMS can enable robust contact between the electrode and skin, reducing motion artifacts. A wireless ECG measurement system was developed and adapted to the polymer electrodes. The polymer electrodes combined with the measurement system were successfully applied in wireless, long-term recording of ECG signals. An eleven-day continuous test showed that the ECG signal did not degrade over time. The results of attach/detach tests demonstrated that the ECG signal was affected by motion artifacts after six attach/detach cycles. The electrodes produced are flexible and exhibit good ECG performance, and therefore can be used in wearable medical monitoring systems. The approach proposed in this study holds significant promise for commercial application in medical fields.
