A team of scientists from KERI (Korea Electrotechnology Research Institute) and the Ulsan National Institute of Science and Technology (UNIST) has been able to 3D-print smart contact lenses without applying voltage.
"Our achievement is a development of 3D-printing technology that can print functional micro-patterns on non-planar substrate that can commercialise advanced smart contact lenses to implement AR," said Dr Seol Seung-Kwon's of KERI.
"It will greatly contribute to the miniaturisation and versatility of AR devices."
Smart contact lenses is a technology that could allow people to directly visualise digital environments, without the need for AR glasses, which are expensive and have been known to cause side-effects such as nausea.
The main expected application area is navigation. Simply by wearing a lens, navigation unfolds in front of a person's eyes through AR. Games such as the popular 'Pokemon Go' can also be enjoyed...
