Invisibility cloak' step closer to reality
The 'Harry Potter' invisibility cloak looks closer to reality after a military camouflage developer applied for patents on its stealth technology.
Hyperstealth Biotechnology's paper-thin material – known as 'Quantum Stealth' – works by bending light around an object to either alter its position or make it vanish, leaving only the background visible.
The Canadian company says it can hide the positions of tanks, troops, artillery and even buildings, reports the Telegraph.
In a video released by Hyperstealth, the material is shown obscuring a miniature tank and small scale fighter jet from view.
The company says the technology requires no power source, can operate day or night and is inexpensive to make.
"One piece of Quantum Stealth can work in any environment in any season at any time of the day or night, something no other camouflage is capable of."
The technology has been in development for several years but the patent application by Hyperstealth – which has built traditional military camouflage – means it is a step closer to manufacturing.
Along with the invisibility cloaking, the company announced three other patent applications using the same material: "solar panel amplifier", a holographic display system and "Laser Scattering, Deviation and Manipulation".
Bringing invisibility cloaking from the realms of science fiction to reality has been a long-standing goal for military technologists.
Earlier this year, declassified papers from the US Defence Department revealed research into invisibility cloaking. In 2016, British soldiers carried out a field trial of a high-tech camouflage material known as Vatec.
