Patients with diabetes have to constantly monitor their sugar levels on a regular basis, by pricking the finger with the blood sugar meter, in the morning before breakfast, and certain cases before and after every meal. Irrespective of how you manage your diabetes, with regular exercise, or controlled diet, this regular blood sugar monitoring helps you figure out how your program is working. But this pricking and injecting can be a tedious job, often messed up, and not as smooth as doctor would do it.
In the past few years, a group of researchers led by Dae-Hyeong Kim from the Institute for Basic Science in Seoul, South Korea, have been working on more convenient ways to monitor diabetes. They have finally come up with a wearable patch that monitors the blood sugar levels and even comes up with medication every time the levels rise.
The technology uses an extremely strong and flexible carbon material, called graphene that is often used in wearable devices. Certain properties of graphene make it difficult to detect changes in sugar levels, but upon adding gold particles or surrounding a gold mesh to the graphene, this wearable can be made to work. Sensors in the patch pick up the sweat from the patient’s skin, detect the temperature changes according to the sweat’s pH, signaling any rise in the sugar levels. When a high level is detected, the heaters in the patch dissolve a layer of the coating, exposing micro needles that release a drug called metofomin, which is responsible for regulating the sugar levels and bringing them back to normal. The metofomin micro needles don’t cause any pain, just a slight tingle. If you are curious about your reading, they can be wirelessly transmitted to mobile phones.
Scientists and doctors across the globe believe that this combination can be effective, by consistently regulating the sugar level throughout the day. But there still are some unanswered questions as to whether this patch would be effective during vigorous exercises and whether this patch would be able to monitor for a full 24 hours.
Another significant improvement in the field of health.
