Stretchable nano-devices towards smart contact lenses—9 February 2016

Researchers at RMIT University and The University of Adelaide, with funding support through the ARC’s Linkage Infrastructure, Equipment and Facilities scheme, 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. 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. “Manipulation of light using these artificial crystals uses precise engineering,” Dr Withawat Withayachumnankul, from The University of Adelaide said. “With advanced techniques to control the properties of surfaces, we can dynamically control their filter properties, which allow us to potentially create devices for high data-rate optical communication or smart contact lenses.”
