Gallium-based liquid metals remain in a state at room temperature and exhibit excellent electrical thermal conductivities, low viscosity, toxicity, making them ideal for creating highly stretchable conductive composites suitable flexible electronic devices. Despite these benefits, conventional single-layer metal face challenges, such as leakage during deformation (e.g., stretching or bending) limited elongation due to incomplete integration of the within elastomer matrix. To address limitations, we introduced bilayer structure into composites, comprising lower polydimethylsiloxane (PDMS) layer an upper PDMS-liquid mixed layer. In layer, precipitates, forming network spanning both layers. This composite demonstrated significantly improved stretchability compared pure PDMS composites. Additionally, by adjusting size content particles, optimized composite’s mechanical properties. Under optimal conditions, spherical particles deform elliptical shapes under tensile stress, increasing pathways reducing resistance. The combined effects particle shape enhanced elongation, supporting its potential electronics applications.

Abstract Electronic skin (e‐skin), a skin‐like wearable electronic device, holds great promise in the fields of telemedicine and personalized healthcare because its good flexibility, biocompatibility, conformability, sensing performance. E‐skin can monitor various health indicators human body real time over long term, including physical (exercise, respiration, blood pressure, etc.) chemical (saliva, sweat, urine, etc.). In recent years, development materials, analysis, manufacturing technologies has promoted significant e‐skin, laying foundation for application next‐generation medical devices. Herein, properties required e‐skin monitoring devices to achieve long‐term precise summarize several detectable field are discussed. Subsequently, applications integrated systems reviewed. Finally, current challenges future directions this This review is expected generate interest inspiration improvement systems.
