A really interesting, complex technology we've been writing about more often is metamaterials, which are able to morph according to their environment. Metamaterials can be 3D printed, and comprise an entirely new class of finely-engineered surfaces which can perform nature-defying tasks. Now, a team comprised of researchers and scientists from the University of Bristol and the University of Sussex has announced its invention of a sound-shaping super-material, which can bend, focus, and shape sound waves which pass through it. This invention could completely transform personal audio, and medical imaging. Read more at 3DPrint.com: http://3dprint.com/166405/sound-shaping-metamaterials/
