This study presents an adhesive, highly stretchable and conformal (ASC) patch for long-term ambulatory ECG monitoring, offering a revolutionary approach to cardiovascular disease diagnosis. The ASC patch demonstrates enhanced mechanical and electrical properties, providing stable high-quality ECG signals in various conditions. This work paves the way for scalable wearable ECG devices and new opportunities in medical applications in soft electronics.
Wearable devices offer a revolutionary approach to ambulatory electrocardiography (ECG) for cardiovascular disease diagnosis. Herein, an adhesive, highly stretchable and conformal (ASC) patch for long-term ambulatory ECG monitoring is presented. The ASC patch is designed with a three-bridge structure to provide inhomogeneous strain distribution during stretching. Meanwhile, the electrical stability is achieved by stretchable liquid metal interconnects at the domain experiencing larger strain. Moreover, the long-term usability can be attained by an adhesive layer made of polydopamine/polyacrylamide glycerol-water hydrogel, maintaining good adhesiveness and stretchability for more than two weeks. Altogether, the patch can successfully measure stable high-quality ECG signals in relaxed, stretched, or underwater conditions. Enhanced mechanical and electrical properties exhibited by our ASC patch confer superior skin-device interface on either dry or wet conditions than that of current electrodes. The hydrogel-based patch displays conformal deformation along with the stretched skin. This work provides a scalable prototype for multilead wearable ECG devices and promises new opportunities for medical applications in soft electronics.
