Abstract

Wearable electrocardiogram (ECG) devices are the mainstream technology in the diagnosis of various cardiovascular diseases, in which soft, flexible, permeable electrodes are the key link in human-machine interface to capture bioelectrical signals. Herein, we propose a self-template strategy to fabricate silver-coated fiber/silicone (AgCF-S) electrodes. With a simple dissolving-curing-redissolving process, the polyvinyl acetate shell around the AgCF core is in-situ removed to form a three-dimensional (3D) multi-channel structure. The conductive fibers overlap each other and pass through the silicon substrate in a network state, so that the electrode can be bent to 180° or stretched to 30%. The 3D multi-channels in AgCF-S adhesive is further coupled with a Kirigami-design structure of flexible substrate, to maintain high flexibility without sacrificing air-permeability, enabling an excellent water evaporation rate of 1.8 μg/mm2/min, and non-allergenic adhere on pigskin after 24 h. Combined with the self-developed standard 3-limb-lead ECG suit, multi-lead signals with high signal-to-noise ratio (SNR) and low variance (σ2), can be transmitted in real-time via Bluetooth and displayed in the client. Typical heart diseases such as coronary, arrhythmia, myocardial infarction, etc., are detected by our ECG equipment, revealing a huge promise in future medical electronics.

为标准三肢导联心电图服自制具有三维多通道结构的皮肤电极模板。
可穿戴心电图(ECG)设备是诊断各种心血管疾病的主流技术,其中柔软、灵活、可渗透的电极是人机界面捕捉生物电信号的关键环节。在此,我们提出了一种自模板策略来制造银涂层纤维/硅树脂(AgCF-S)电极。通过简单的溶解-固化-再溶解过程,AgCF 内核周围的聚醋酸乙烯外壳被原位去除,形成三维(3D)多通道结构。导电纤维相互重叠,以网络状态穿过硅衬底,因此电极可以弯曲到 180° 或拉伸到 30%。AgCF-S 粘合剂中的三维多通道进一步与桐木设计结构的柔性基板相结合,在不牺牲透气性的情况下保持了高柔性,使水蒸发率达到 1.8 μg/mm2/min,且在猪皮上附着 24 小时后不会过敏。结合自主开发的标准三肢导联心电图服,可通过蓝牙实时传输高信噪比(SNR)和低方差(σ2)的多导联信号,并在客户端显示。我们的心电图设备可检测出冠心病、心律失常、心肌梗塞等典型心脏病,为未来的医疗电子技术带来了巨大前景。
