摘　　要：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 1.8μg/mm^(2)/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.
