Shape Memory Polymers: Magnetic Shape Memory Polymers with Integrated Multifunctional Shape Manipulation (Adv. Mater. 4/2020)

In article number 1906657, H. Jerry Qi, Ruike Zhao, and co-workers present a novel magnetic shape memory polymer that uses the embedded magnetic particles to regulate the material stiffness and induce actuation. This enables integrated shape-manipulation functions, including untethered rapid reversible shape change, sequential actuation, shape locking, and reprogrammability. The integrated functions permit applications such as soft grippers with large grabbing force, morphing electronics, and minimally invasive biomedical devices.
