Six chest leads are the standardized clinical devices of diagnosing cardiac diseases. Emerging epidermal electronics technology shift the dangling wires and bulky devices to imperceptible wearing, achieving both comfortable experience and high-fidelity measuring. Extending small areas of current epidermal electronics to the chest scale requires eliminating interference from long epidermal interconnects and rendering the data acquisition (DAQ) portable. Herein, we developed a chest-scale epidermal electronic system (EES) for standard precordial-lead ECG and hydration monitoring, including the only μm-thick substrate-free epidermal sensing module and the soft wireless DAQ module. An electrical compensation strategy using double channels within the DAQ module and epidermal compensated branches (ECB) is proposed to eliminate unwanted signals from the long epidermal interconnects and to achieve the desired ECG. In this way, the EES works stably and precisely under different levels of exercise. Patients with sinus arrhythmias have been tested, demonstrating the prospect of EES in cardiac diseases.

用于标准 6 胸前导联心电图的胸部自补偿表皮电子设备

六导联是临床诊断心脏病的标准化设备。新兴的表皮电子技术将悬垂的电线和笨重的设备转变为不易察觉的佩戴,实现舒适体验和高保真测量。将当前表皮电子设备的小区域扩展到胸部规模需要消除长表皮互连的干扰并使数据采集 (DAQ) 便携。在此,我们开发了一种用于标准胸前导联心电图和水合作用监测的胸部尺度表皮电子系统 (EES),包括唯一的 μm 厚无基底表皮传感模块和软无线 DAQ 模块。提出了一种在 DAQ 模块和表皮补偿分支 (ECB) 内使用双通道的电补偿策略,以消除来自长表皮互连的不需要的信号并实现所需的 ECG。这样,EES在不同的运动水平下都能稳定、准确地工作。对窦性心律失常患者进行了测试,证明了 EES 在心脏病中的前景。
