A dual cross-linked magnetic polymer solves the fundamental trade-off limiting soft artificial muscles, achieving unprecedented combinations of stretchability, force output, and shape-programming ...

Thermoset polymers underpin many high-performance applications because covalent cross-linking yields stability, chemical resistance, and robust mechanics.

Soft robots are only as capable as the artificial muscles that drive them, and for years those muscles have forced a trade-off between strength and flexibility. A new magnetic polymer design is ...
