Programming of Complex Magnetic Profiles Enforced by 4D Printed Magnetic LCE Actuators
Advanced Materials, EarlyView.A 4D printing‐enabled magnetic programming strategy is introduced in which thermally actuated liquid crystal elastomers are magnetized in their target shape to encode complex three‐dimensional magnetic profiles. The resulting actuators achieve multistate shape morphing and programmable locomotion under low magnetic fields, without requiring specialized
