If the adaptive camouflage requires a power source, this must weigh no more than 0.45 kilograms and provide at least 8 hours of operation. They also need to function across a wide range of temperatures, in rain and snow, and without hampering a soldier’s normal duties. These need to work in all terrain from all angles. Those selected for the following one-year phase will submit 10 prototype uniforms for testing. ![]() The wearer would be effectively transparent at some wavelengths but not all, rendering them as a coloured shadow or ghost image.Ĭontractors will demonstrate the feasibility of their approach in the first six months of the programme. “This means that you may see less of something at a particular colour, but see it at all other colours,” says Wegener. His team has created cloaks from photonic crystals that work for certain wavelengths, but bending light over the entire spectrum is forbidden by relativity. “Complete invisibility of macroscopic objects for all visible colours is fundamentally impossible,” says Martin Wegener of the Karlsruhe Institute of Technology in Germany. So how will they manage this? Metamaterials are probably the best solution: previous efforts in this field using technology like LEDs were hampered by power and computing requirements.īut although they can bend light, metamaterials cannot make things disappear completely. ![]() Now the US army has made a call for proposals from companies for wearable camouflage with a chameleon-like ability to change according to the background. Since then, many devices trumpeted as invisibility cloaks have been described, but they only work in the lab with specific wavelengths or from certain angles. In 2006, John Pendry, a theoretical physicist at Imperial College London, showed that it should be possible to bend light around an object and hide it using metamaterials – structures engineered at microscopic levels to channel electromagnetic waves. Seems a bit unrealistic? Well, we may not be as far away as you think. Not just that – it has announced that it wants to test the best contenders within the next 18 months. In anticipation of the problems invisibility could cause, the company is already working on technology that could detect cloaked items.The US army wants invisibility cloaks for its soldiers. Hyperstealth Biotechnology Corp believes that the Quantum Stealth material represents a major breakthrough for the field. But the results fell short of true invisibility. In the past, scientists have tried using electromagnetic waves and man-made substances, called “metamaterials". Harry Potter's cloak aside, creating a true invisibility cloak has long been seen as a near-impossible task. It has also applied for patents for a holographic-like display system. Hyperstealth Biotechnology Corp, known for its camouflage products, has already applied for a patent for the Quantum Stealth material. The light-weight material can be bent and folded and is designed to be carried in a soldier’s backpack, and it can also be used to make parachutes. A video clip demonstrating the Quantum Stealth showed how it could potentially cloak over tanks and other military hardware. The company says that its ultrathin, light and mobile form makes it ideal for military action. It also blocks ultraviolet, infrared and shortwave infrared waves. It works by bending light rays, rendering objects behind it invisible. The material, Quantum Stealth, resembles a gadget from a Mission Impossible film. The portable material does not require an energy source and has been marketed for military use. Spotted: Canadian company, Hyperstealth Biotechnology Corp, has created a paper-thin material that makes objects “invisible”.
