A team of scientists from the Seoul National University, South Korea, developed a sensor that can monitor blood sugar level by analyzing sweaty skin.
The patch has three sensors. It is flexible and can move with the skin. Human sweat contains less sugar than blood and other chemicals, so the scientists needed to overcome a series of challenges to make the patch work.
Inventing the patch, the scientists were trying to overcome the need for painful blood collection. In their study, the researchers conclude: “The current system provides important new advances toward the painless and stress-free care for diabetes”.
A recent report brings good news for the patients with type 1 diabetes, as an artificial pancreas that continuously monitors blood glucose level and delivers insulin to the body as and when needed can reach patients within the next two years.
Current insulin delivery methods do not account for variability of insulin needs in patients with type 1 diabetes, as the amount of insulin a patient needs can change from day to day, depending on the diet, physical activity lessons, and in case with women, depending on changes in insulin during menstruation.
In the new report, Drs. Roman Hovorka and Hood Thabit explain how an artificial pancreas could offer a less invasive and more effective treatment for the patients with type 1 diabetes. It could eliminate the need for them to measure blood glucose continuously and deliver insulin only when needed.
