Combined with LED design, intelligent contact lenses can detect blood sugar

Google has announced that it wants to build a smart contact lens to monitor users' blood sugar, but there is no clear result. After Google, the National Institute of science and Technology (National Science and Technology), Ulsan, South Korea, led by Professor Park Jang-Ung, successfully designed a similar product without a needle to test the user's blood sugar. Contact lenses are combined with LED design, normally open, and when the people wearing contact lenses exceed the standard blood sugar, they automatically turn off.

The intelligent contact lens contains a mixture of objects, transparent conductors, and many functional devices, including LED in functional devices. When using a smart contact lens, power transmission through an contained small antenna, LED pixels in the lens and glucose sensor are activated. Once the blood sugar values are detected over the tears, the resistance of the sensor will be reduced, the resistance of the LED series circuit is increased, and the LED light source will turn off automatically to remind the user to pay attention.

The research team mentioned in the report that the microminiaturization of blood glucose detection allows users to detect blood sugar without the need for large testing instruments. At the same time, the report also pointed out that the smart contact lens template can be quickly made, combined with the traditional processing methods, is conducive to large-scale production in the future. Although the product has been used in rabbit experiments, the team also says there is no side effects, but there is no human experiment. Scientists have doubts about whether the glucose oxidase in the sensor can damage the eyes, and how to prolong the life span, and can not ensure that the tears can be achieved through the tears. The blood sugar of the human body was measured.
