A team of physicists are one step closer to creating a Harry Potter-style invisibility cloak, with a new form of material that could also be attached to contact lenses to provide 'perfect' eyesight. Using tiny atoms that can interact with light, the St Andrews' researchers have developed a flexible new 'smart' material that could theoretically appear invisible to the naked eye.
Flexible smart materials that can manipulate light to shield objects from view have been much-theorised but now researchers in Scotland have made a practical breakthrough that brings the possibility of an invisibility cardigan – or any other item of invisibility clothing - one step closer.
Two challenges to the creation of smart flexible materials that can cloak from visible light are making meta-atoms small enough to interact with visible light, and the fabrication of metamaterials that can be detached from the hard surfaces they are developed on to be used in more flexible constructs.
Research published today, Thursday 4 November 2010, in New Journal of Physics, details how Meta-flex, a new material designed by researchers from the University of St Andrews, overcomes both of these challenges.
