A flexible and extremely thin device that adheres to the skin like a tattoo sticker is able to monitor blood sugar levels. The sensor has the potential to get rid of the finger pricks required by many diabetics
Scientists have succeeded in developing a flexible and very thin device that adheres to the skin like a tattoo sticker and is able to monitor blood sugar (glucose) levels. The sensor, the details of which are described in an article published long ago in the scientific journal Analytical Chemistry, has the potential to eliminate the finger pricks required of many diabetics.
The researcher Joseph Wang and his colleagues from San Diego make it clear that diabetes affects hundreds of millions of people around the world. Many of these patients are required to monitor their blood sugar levels daily in order to treat the disease. However, the usual method of testing the blood sugar level requires the pricking of the finger to extract a drop of blood which is tested by a monitoring device. The pain associated with this method may discourage patients from properly recording their blood sugar records. Over the years, a wristband was developed to monitor blood sugar, but such a band causes skin irritation and its marketing has been discontinued. The research team wanted to find a more efficient approach.
The researchers developed a system that can be worn on the wrist, one that does not cause irritation, and which is able to monitor the sugar levels in the liquid just below the skin layer, a system based on a combination of sugar suction and electrochemical biosensing. Preliminary tests done among seven healthy volunteers showed that the system is able to accurately determine the blood sugar level. The researchers conclude and say that the device could be used in the future to treat diabetes and monitor other conditions in the body, for example kidney diseases.

This is a great invention.
Is there evidence for the attempt?
It's hard for me to understand an illustration
