Researchers develop 3D printed acoustic metamaterials that can be switched on and off remotely using a magnetic field. Researchers have been pushing the capabilities of materials by carefully designing precise structures that exhibit abnormal properties that can control acoustic or optical waves. However, these metamaterials are constructed in fixed geometries, meaning their unique abilities are always fixed. Now, new 3D printed metamaterial developed by a team led by University of Southern California researchers can be remotely switched between active control and passive states.
