(ChattahBox) – Invisibility technology is growing year by year. But scientists have now made the promising leap of creating an ‘invisibility cloak’ out of silk, which is capable of bending light around solid objects.

The metamaterial has been created by scientists working out of Tufts University and Boston University, made of silk that has been coating in a thin, flexible layer of gold.

So far, it can only work in the spectrum of terahertz waves – that mysterious space between radio and infrared light. But according to Discovery News, the implications clearly show progression into a wider light spectrum is entirely possible.

“This is an unusual angle for a metamaterial because of silk’s ability to interface with the human body,” one of the researchers, Fiorenzo Omenetto, said of the cloak.

The fact that the silk makes it light weight and flexible is especially promising, so we will have to keep an eye on the development of this technology.

The study has been published in Advanced Materials.
