Abstract Bioelectrode is critical to many biomedical researches. However, traditional materials (typically noble metals) and manufacturing techniques limit the large‐scale production of bioelectrodes. Herein, a fast electrochemical approach proposed deposit versatile MXene/polydopamine (PDA) composites on metalized substrate. PDA coating can improve adhesion between MXene substrate, while provides rough surfaces with unique micro/nanostructure outstanding electrical/optical/thermal performance. The impedance as‐prepared bioelectrode at 1 kHz down 8.48 Ω cm 2 . corresponding cathodic charge storage capacity (CSC c ) injection (CIC) are up ≈250 6.59 mC −2 respectively, much superior that bare Pt other conventional material‐based electrodes.

Abstract Hydrogel‐based electrodes are widely used in electrophysiological monitoring for personal disease prevention and home‐based healthcare. However, limited by the hydrogels’ low toughness, poor adhesion, weak electrical stability, motion artifacts device detachments inevitable after long‐term, continuous monitoring. Herein, novel liquid metal@silk fibroin peptide (LM@SF) core‐shell particles, which shell SF not only facilitates core LM's dispersion but also stabilizes free radicals, designed to initiate situ formation of hydrogel while simultaneously enhancing its conductivity. As applied monitoring, can maintain both a stable physical interface transmission skin, thus promoting signal acquisition quality obviously even during exercise long‐term wearing. At last, portable flexible patch with small volume (70 × 35 2 mm) light weight (7 g) is developed achieve electrocardiogram (ECG) via wireless transmission, demonstrating high potentials telemedicine.
