Smart Contact Lens Developed in Korea
September 17, 2018
A research team from Ulsan National Institute of Science and Technology (UNIST), South Korea, has developed smart contact lenses to detect glucose. The contact lenses were integrated with glucose sensors, wireless power transfer circuits and LED pixel which can monitor the glucose level in tears and provide instant sensing result via the embedded LED display. The lenses have been tested on rabbits without adverse effect and the result was published on Science Advances in January.
Smart clothes with communication and other functions may soon become products in the market with the development of LED embedded fabric. Researchers of MIT and its associated research institute, Advance Functional Fibers of America (AFFOA) have produced fibers incorporated with LEDs, which are waterproof and can transmit optical signals. Commercial products adopting the technology for biomedical and communication applications are expected to launch in 2019.
