Many patients with diabetes would be happy to see the back of their blood glucose monitor and the daily finger-prick tests. Enter: a team of scientists from the Ulsan National Institute of Science and Technology (UNIST), South Korea, who have created a means of wirelessly monitoring glucose levels with a soft contact lens.

“Embedded within our smart contact lens are electronic circuits, an antenna, a glucose sensor and LED pixels integrated as stretchable forms,” explains Jang-Ung Park (1). “This improves the comfort and wearing-time of the lens compared with previous smart lenses that were hard due to having brittle and more

rigid components.”
