Equipped with sensors and LED smart contact lenses, blood glucose can be measured anytime, anywhere
The concept of smart contact lenses has emerged for many years, whether it is Google's blood glucose, vision correction contact lenses, or SONY and Samsung's blinking camera capabilities, manufacturers have intended to win everyone's attention, but smart contact lenses to be both comfortable and Performance is not an easy task, the major manufacturers are still in the research and development stage.

Recently, UNIST, Korea's Ulsan Institute of Science and Technology (UNIST), has also begun researching smart contact lenses. They test blood glucose using sensors and LEDs in soft contact lenses. When the blood glucose level in the tear is too high, the green LED stops blinking , Remind the user.
Diabetes patients in the current blood glucose test, the general use of blood lancing needle poked their fingers or sebaceous pin, the patient had to bear the inconvenience of the appliance and tingling, if the study was first developed, for patients with diabetes is a Gospel.
The current blood glucose detection
To help patients feel uncomfortable, the team created a soft, flexible, transparent electronic assembly that uses an antenna and rectifier to convert RF power from nearby generators to electricity that power the glucose sensor and the LED , And LED light-emitting direction, the wearer will not see the flashing green LED.
However, this study has not been used in human clinical practice, only for animal experiments, and researchers did not find any adverse reactions, guiding scientist Jihun Park said the sensor can accurately track the blood sugar in tears.
This product still needs continuous research and development. According to David Walt, a diagnostic expert at the Wyss Institute in Harvard University, there are still some problems to be solved.
Glucose sensors use glucose oxidase (Glucose Oxidase) in the device to measure blood glucose, but glucose oxidase and sugar combine to produce hydrogen peroxide, which can damage the eyes. And as time goes by, the glucose oxidase content of the device will also drop, have to find ways to extend the life of contact lenses.
Park also said that such smart contact lenses also have room for improvement and will work with other vendors to solve problems. According to sources, in addition to Verily (formerly Google X), some manufacturers such as Sensimed, EPGLMed, Samsung, SONY and Apple will also need to launch smart contact lenses in the future.
