Diabetes: goodbye finger pricks! Here comes the patch that measures glucose levels

Here is the patch that measures diabetes and manages to record the patient's blood sugar in a non-invasive way.

A patch that measures blood glucose levels. Patients with diabetes will soon be able to say goodbye to finger pricks and apply a patch to the skin that provides an accurate measurement every 10-15 minutes.

It is a new device developed by researchers at the University of Bath, in the United Kingdom, who, coordinated by Richard H. Guy, have created a sort of mechanism capable of analyzing the sugar present in subcutaneous fluids.

Consisting of microsensors powered by a small electric current, which pick up the sugar present in the fluids stored in the hair follicles, the patch extracts and collects the glucose, which is then measured every 10-15 minutes for several hours. Thanks to this system, the device does not require a calibration and therefore can be used by the patient without having to perform any puncture.

“A non-invasive, no-prick method of monitoring blood glucose has proven to be a difficult goal to achieve. Those that came closest still required a finger prick in order to be calibrated or the implantation of a pre-calibrated sensor via a single prick. Our monitoring device requires no calibration and makes an essential contribution in the fight against the increasing prevalence of diabetes around the world, ”explains Richard H. Guy.

As explained in the study, the patch features a series of microsensors that are powered by a small electric current. These take the sugar found in the fluids stored in the hair follicles and, in this way, the extracted glucose is collected in small tanks and measured every 10-15 minutes for several hours throughout the day. Thanks to this mechanism, the device does not require a calibration and, therefore, can be used by the patient without having to perform any puncture.

During the trial, the patch was shown to be able to detect changes in blood glucose during the day. Once on the market, the device should also transmit blood glucose measurements via smartphone, in order to let you know immediately when to take insulin or drugs.
