Researchers from the Georgia Institute of Technology and Ohio State University have developed a soft polymer material, called magnetic shape memory polymer, which uses magnetic fields to change into a variety of forms. The newly developed material is a blend of three distinct ingredients, all with different features: two types of magnetic particles, one for inductive heat and one with strong magnetic attraction, and shape-memory polymers to help lock various state shifts into place. Researchers believe the new material could enable a range of new applications from antennas that change frequencies on the fly to gripper arms for fragile or heavy gadgets.
