Researchers in Germany have created the first mechanical invisibility cloak. When this cloak is placed over an object, the object cannot be felt at all — either by your finger, or a more sensitive measuring device.
This mechanical cloak, created by the Karlsruhe Institute of Technology (KIT) in Germany, much like most other modern invisibility cloaks, is fashioned from a metamaterial. While an optical metamaterial bends light in a weird, not-seen-in-nature way, KIT’s mechanical metamaterial has a special structure that redirects physical force in a special way. KIT’s new metamaterial is constructed out of “needle-shaped cones” of polymer that are arranged in a crystalline lattice. It sounds like the mechanical metamaterial starts life as a big lump of polymer, and then a 3D laser lithography machine creates the exact right shape.
