Monitor your blood glucose levels by simply wearing a ring: no more annoying finger pricks or inaccurate results. It seems like a dream? Well, at the moment it is. But thanks to the pioneering work of Hoyeong Kwon e Andrea Alù, this dream could become reality. I'll link the search here.
Goodbye to invasive methods
Continuous and accurate monitoring of blood glucose levels is critical to effectively manage conditions such as diabetes. Until now, direct methods for measuring blood sugar require piercing the skin to obtain a blood sample. Existing non-invasive alternatives, however, measure glucose only indirectly, using tears or sweat, with delayed and imprecise results.
Now, the ring proposed by Kwon and Alù promises to revolutionize glucose monitoring, offering non-invasive, direct and clinically useful measurements.
Radio waves at the service of health
How does this innovative device work? The ring, placed on a finger, sends radio frequency electromagnetic waves through the skin. Integrated detectors and amplifiers detect the dispersion of the electromagnetic field, which has a peak intensity (a resonance) related to the concentration of glucose in the blood.
The results show a linear relationship between the resonance frequency and the glucose level, with a sensitivity of 10 mg/dL. Considering that normal fasting blood sugar values range from 70 to 100 mg/dL, the ring can provide meaningful and timely feedback to the user.
A ring to measure blood glucose: a better future for diabetics
This smart ring represents a huge step forward in data management diabetes and other conditions related to blood glucose. Its non-invasive nature and accuracy make it a promising solution for improving the quality of life of millions of people.
Imagine a future where diabetics can constantly monitor their glucose levels without pain or discomfort. A future in which the complications of diabetes can be prevented with a simple daily gesture.
With further development and testing, this device could become an essential tool. And who knows, maybe one day everyone will be able to benefit from this technology, even the "healthy", monitoring their health easily and painlessly.
