  • Mechanical properties (stretchability, tensile strength, toughness) and adhesion to skin were characterized.
  • Electrophysiological signal acquisition and machine learning-based classification were performed.

    • Main Results:

    • The hydrogel exhibited exceptional stretchability (1643%), high tensile strength (366.54 kPa), and toughness (350.2 kJ m⁻³).
    • It demonstrated stable, reusable adhesion to human skin (104 kPa), enabling conformal contact.
    • High-quality epidermal electrophysiological signals were captured with a high signal-to-noise ratio (25.2 dB) and low impedance (310 ohms).
    • Machine learning algorithms achieved a 91.38% attention classification accuracy.

    Conclusions:

    • The proposed liquid-metal-induced method offers a simple and efficient route to high-performance conductive hydrogels.
    • The developed hydrogel shows significant potential for wearable electronics, biosensing, and human-computer interfaces.
    • Integration with machine learning opens avenues for advanced applications in healthcare, education, and artificial intelligence.
