Electronic skin (e-skin) has been extensively investigated for its potential application in heart health monitoring, such as screening cardiovascular diseases and evaluating cardiac activity. Nevertheless, the poor electrical stability of traditional metal electrodes insufficient adhesion ordinary flexible substrates are primary impediments that hinder further product marketing healthcare field. Herein, we propose a novel integrated e-skin incorporates embedded stretchable with high (within 20% strain) microsucker array improved adhesion, which facilitates effective reduction motion artifact interference. Moreover, wireless monitoring system based on is designed to realize synchronous electrocardiogram (ECG) ballistocardiogram (BCG) detection by collecting chest epidermal mechano-acoustic signals vibration-voltage signals. The results same adult volunteer indicate ECG BCG data recorded this have good consistency from commercial devices. Furthermore, signal different volunteers validated disease diagnosis long-term monitoring.

Currently, highly stretchable conductive fibers have become one of the most important components flexible electronics due to their excellent conductivity, adaptability, and knittability. In this work, a fiber was developed with thermoplastic polyurethane (TPU) core composited sheath liquid metal particles (LMP) multiwall carbon nanotubes (CNTs) by simply dip coating then permeated encapsulated waterborne (WPU) layer. After mechanical sintering, resulting WPU/LMP-CNTs/TPU (WLCTF) exhibited ultrahigh reaching 1.15 × 106 S/m, along remarkable linearity (R2 = 0.997) across large strain range 160%. The WLCTF molded process into helical electrodes, which provided stable signal output at 1700% an extremely high-quality factor 5483.9 (helical index 7). Notably, these can be woven fabric substrates possess Joule heating capabilities waterproof properties; in addition, is engineered efficiency recycling. With its consistent sensing capabilities, electrical recyclability, properties, holds significant potential for advancement fields wearable technology.
