Powerful! Equipped with LED wisdom lenses to test blood glucose

The concept of wisdom stealth glasses has been for many years, whether the levels of blood glucose and Google corrective lenses, or SONY and Samsung blink camera, they are interested in for attention, but smart contact lenses are both comfortable and performance is not an easy thing, the major manufacturers are still in the development stage.

Recently, South Korea Ulsan National Institute of science and Technology (UNIST) also began to study the wisdom of contact lenses, using soft contact lenses in the sensor and LED to test the blood sugar, blood sugar in tears when the value is too high, the green LED will stop flashing, remind users.

At present, the diabetic patients in recovery test blood sugar, commonly used blood taking needle poke my finger or pin in sebum, patients suffer appliances carrying inconvenience and tingling, if this study first developed for patients with diabetes is a great boon.

In order not to let the patients feel unwell, transparent electronics team to create a soft and flexible, the antenna and the rectifier (Rectifier), it can be converted into electricity generator RF nearby, who will charge for glucose sensor with LED power supply, and the LED light emitting direction outwards, the wearer will not see flashes of green light LED.

LED is a semiconductor electronic component capable of emitting light, has the advantages of small size, energy saving, no electromagnetic interference and other advantages, the application range more widely, to the advertising panel, LED LiFi optical communication from highly optimistic about, LED is now ubiquitous and lighting lamps. In the concept of wisdom lenses can also be found in the LED.

But the study has not yet been used in human clinical, only for animal experiments, the researchers found no adverse reactions, guiding scientist Jihun Park said that the sensor can accurately track the tears of blood sugar.

But this product is still need to continue research and development, Harvard University Wyss Institute Institute diagnosis expert David Walt pointed out that there are still some problems to be solved. The glucose sensor is using glucose oxidase in equipment (Glucose Oxidase) to measure blood glucose, but glucose oxidase combined with sugar will produce hydrogen peroxide, may damage the eyes. With the passage of time, the content of glucose oxidase in equipment will also decline, have to think of ways to extend the life span of contact lenses.

Park also said the wisdom of contact lenses also has room for improvement, and will solve the problems together with other manufacturers. According to the news, in addition to Verily (formerly known as Google X), some manufacturers such as Sensimed, EPGLMed, Samsung, SONY and Apple will be launched smart contact lenses.
