Invisibility Suit?

. Tuesday, November 17, 2009

I love technology. Many things that have been generated by technological. Have you thought of wearing a cloak that makes you invisible? Although the cloaks may sound like something from Harry Potter, researchers in London were today given the go ahead for a £4.9 million project to create a real invisibility suit. In Rowling's stories, Harry Potter uses his cloak to move around his school unseen.

Today, researchers at Imperial College said such a garment could soon become a reality. They hope to create a cloak from a new material that can manipulate light.

We can see an object when light hits an object, it bounces off the surface and into the eye and making the object visible. The invisibility cloak made from 'meta-material' would work by 'grabbing hold' of light waves and making them flow smoothly around an object, in the same way that water in a river flows round a stick.

Putting the cloak on would render the wearer invisible to the human eye. The team at Imperial College say the meta-material could have a range of other applications, including creating super-sensitive microscopes and airport security sensors that can spot tiny amounts of chemicals.

However, they admit the Harry Potter cloak is likely to generate the most interest. Sir John Pendry, who is leading the project, which is being funded by the Leverhulme Trust and will be carried out with the University of Southampton, said: 'We've shown that an optical invisibility cloak is theoretically possible - the big challenge now is to build it.'
