Generally how a person can see the objects or anything, the light falls on the objects and it reflects back to our eye. It makes the visibility.
If we stop that reflection of light back, then any object can be invisible or even human can also be invisible to others.
So the researchers used Carbon-nanotubes to create invisibility. And named the device as Mirage Effect Device.
This invention is based on the properties of Carbon-nanotubes. Especially the one that allows them to conduct heat and send it to nearby areas.
A group of researchers from the University of Dallas managed to come up with a functioning cloaking device that can be activated or deactivated and which can virtually hide objects by generating a mirage.
See this video to know how Mirage Effect make the objects invisible....
Mirage(an optical illusion caused by atmospheric conditions, esp. the appearance of a sheet of water in a desert or on a hot road caused by the refraction of light from the sky by heated air).
It would be interesting to mention that the mirage effect that can be often seen in deserts represents an optical phenomenon in which the heat bends the rays of light and thus a displaced image of the sky or objects located far away is generated.
With the help of electrical stimulation, researchers heat the see-through sheet of carbon nanotubes in order to reach high temperatures. Then the nanotubes transmit that heat to the surrounding area, which leads to a steep temperature gradient. The rays of light thus dodge the object located behind the machine, producing the illusion that nothing is there.
Now British army is trying to make invisible military tankers. In just five years the British Army could boast invisible tanks. The new technology makes use of complex electronic sensors that project the surroundings, thus merging the tank with the environment and making it almost impossible to spot. It is worth mentioning that the invisible tank is the project of the BAE's Future Protected Vehicle Program. The latter will be implemented in 7 manned and unmanned vehicles.
