Graphene-based patch can help monitor blood sugar levels

Hui Gained Yun/Seoul Nationwide College

This see-via patch manufactured from graphene and studded with gold is not only a trend accent or momentary tattoo. It has the potential to watch your blood sugar ranges and ship diabetes medicine. The prototype, designed by Seoul Nationwide College assistant professor Dae-Hyeong Kim and a group of researchers, has sensors that may detect your temperature and the pH/chemical composition of your sweat. It then beams the info it collects to an accompanying smartphone app. If the system infers that you simply want drugs based mostly on the state of your sweat, the app computes for the quantity of treatment (metformin for sort II diabetes) you want. The patch’s microneedle array then injects the correct quantity into your physique.

Whereas it might save somebody’s life sooner or later, the present model is way from being a product individuals can depend on. At its present type, the microneedle array prompts when the bracelet detects that the temperature’s a hundred and five levels Fahrenheit. That makes it sick-fitted to use within the tropics and different usually heat places. Additionally, it is incapable of delivering sufficient metformin that adults want. The group nonetheless has to determine tips on how to repair that with out having to create an unlimited model crammed to the brim with teensy needles.
