Episode 14: Mechanical metamaterials reprogrammable via magnetic interactions

In this podcast episode, MRS Bulletin’s Sophia Chen interviews Daniel Garcia-Gonzalez from Universidad Carlos III de Madrid in Spain about his research group’s reprogrammable metamaterial. The researchers use a soft polymer, mixed with magnetic particles. By rotating the orientation of the magnets, they tune the softness or compressibility of the material. This work was published in a recent issue of Advanced Materials.
