Shape memory polymers (SMPs) are smart materials that enable to transform back to their original shape from the deformed state when subjected to external stimuli. They have shown great potential used as sensors and actuators in diverse applications. However, current research on SMPs primarily focuses on the utilization of a single source of stimuli (e.g., electricity, magnetism, light, etc.), which...
Magnetic Field‐Assisted 4D Printing
In article number 2314854, Tianyu Yu and co‐workers 4D print electrically/magnetically dual‐driven shape memory composites using magnetic field‐assisted photopolymerization techniques. Carbon nanotubes and magnetic particles reinforced layers are alternatively fabricated to gain shape memory actuation from a) high frequency alternating magnetic fields or b) electric...
