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 ...

A dual cross-linked magnetic polymer solves the fundamental trade-off limiting soft artificial muscles, achieving ...

Despite their remarkable flexibility, today’s soft artificial muscles struggle to deliver meaningful force. This ...

Cross-linking polymers simply means adding bonds across polymer strands, explains Jeremy E. Wulff, a chemistry professor at the University of Victoria who led the work. Silicone bakeware, certain ...
