Highlights A conductive, stretchable, adaptable, and self-healing, GaInSn/Ni--based composite hydrogel by incorporating a magnetic liquid metal into the hydrogel framework through crosslinking polyvinyl alcohol with sodium tetraborate. The multifunctional composite hydrogels showed outstanding performance for magnetic repair movement sensing, and EMI shielding.
