Researchers at RMIT University and the University of Adelaide have joined forces to create a stretchable nano-scale device to manipulate light
The device manipulates light to such an extent that it can filter specific colours while still being transparent and could be used in the future to make smart contact lenses.
Using the technology, high-tech lenses could one day filter harmful optical radiation without interfering with vision – or in a more advanced version, transmit data and gather live vital information or even show information like a head-up display.
The light manipulation relies on creating tiny artificial crystals termed “dielectric resonators”, which are a fraction of the wavelength of light – 100-200 nanometers, or over 500 times thinner than a human hair.
The research combined the University of Adelaide researchers’ expertise in interaction of light with artificial materials with the materials science and nanofabrication expertise at RMIT University.
