MIT researchers have developed flexible, layered metamaterials textured with nanoscale wrinkles that could provide a new way to control the distribution of sound or light signals, such as changing the materials’ color or making it optically or acoustically invisible.
The technology could be used for nondestructive testing of materials, new medical diagnostic tools, and sound suppression in a certain volume (location) in space rather than just a single spot, as in current noise-canceling headphones, for example.
