Liquid‐Metal‐Enabled Materials Design for Soft Electronics

ABSTRACT Liquid metals (LMs), particularly gallium‐based alloys, have garnered increasing interest owing to their unique combination of metallic conductivity and fluidic deformability. By integrating LMs with various elastomers to form composites, researchers have unlocked remarkable potential in soft electronics, robotics, and biomedical devices. This review systematically summarizes the fundamental properties of LMs and highlights key design strategies, including composite formulation and architectural designs tailored to specific functionalities. Representative fabrication methods and their associated scalability‐resolution trade‐offs are further discussed. Finally, emerging applications in soft electronics and biomedical systems enabled by these tailored LM‐based materials are examined. This review aims to bridge the gap between material design and practical implementation, providing insights to guide the development of advanced wearables and intelligent stretchable electronics.
