Put it on your arm and measure glucose...Diabetes Management Easier!

Korean researchers have developed a wearable sensor that can measure glucose in sweat.

The developed sensor changes the brightness of the micro LED depending on the concentration of glucose, so it can be easily attached anywhere in the body to monitor blood sugar without blood collection.

Diabetes, one of the most common chronic diseases.

Diabetes patients have to poke their fingers frequently to check their blood sugar levels, or glucose levels in the blood, which is inconvenient.

Korean researchers have developed a wearable sensor that can be attached to the skin and determine the amount of glucose in sweat with the brightness of light.

The researchers created a sensor that integrates transistors and micro LEDs on a thin substrate of 4㎛, which is 1/20th the thickness of the hair.

The sensor contains an enzyme that reacts with glucose, and the intensity of the current changes through the transistor depending on the concentration of glucose.

If there is a lot of glucose, the current decreases, which weakens the brightness of the micro LED.

Conversely, less glucose will light up the LED.

The developed sensor uses a coin-sized battery, and the researchers plan to develop it into a wireless power system in the future.

[Wonryeong Lee / Senior Researcher at KIST] We are currently developing a wireless circuit that makes this battery-free. We're implementing a wireless power transmission method that allows you to put your smartphone right away..]

A wearable sensor that can be attached to our body to measure our health anytime, anywhere.We look forward to seeing whether

will be a new turning point in health monitoring in that it is light and thin and can be easily used by anyone with just light.
