Garmin Patents Smartwatch Tech for Blood Sugar Monitoring
Garmin is working on a smartwatch feature that could track your blood sugar levels without needing to prick your finger.
It uses light to see how your blood absorbs it, which can help estimate your average blood sugar levels over a few months (HbA1c).
The watch would shine a special light into your skin, and sensors would measure how the light changes.
This technology is still in the patent stage, so it might be a while before it's available.
If it works, it could provide an easy way to monitor your health, especially if you are concerned about diabetes.
Garmin has patented a method for non-invasive blood sugar monitoring in smartwatches.
The technology aims to estimate HbA1c levels using pulse spectrometry.
Pulse spectrometry uses light to detect chemical changes beneath the skin.
The device would analyze multi-wavelength PPG signals to estimate glucose levels.
The technology is in the patent stage; other companies are also working on similar features.
