Controlling glucose levels without having to resort to puncture is a dream of many patients and doctors.
Now, a material like the newcomer of the future, graphene, can measure the amount of blood sugar.
The researchers, directed by Dae Hyeong, have taken another step, by adding microagujas capable of administering, through the skin, the necessary dose of an antidiabetic (metformin), when glucose levels rise.
The transparent bracelet appearance there are several integrated chips that measure glucose levels.
It is the only device approved by US health authorities.
The researchers point out that graphene is a material with great potential to be used in electronic devices of this type, as it is flexible, it conducts electricity, and can be soft, fine and transparent.
