MIT's new blood sugar monitor skips the finger pricks
MIT researchers have built a device that checks your blood sugar using light—no more painful finger sticks.
It uses a technique called Raman spectroscopy, shining safe light on your skin to measure glucose levels quickly and accurately.
Smaller, faster, and aiming for smartwatch size
The team shrunk the device from desktop to shoebox size by focusing on just three key signals, making it simpler and cheaper.
Each test takes about 30 seconds and matches the accuracy of current monitors that need skin insertion.
They're now working on making it even smaller, with the eventual goal of smartwatch size, and are working to ensure it performs consistently across all skin tones.
Years in the making, big hopes for diabetes care
This breakthrough builds on 15 years of research and a clever 2020 discovery that helped isolate glucose signals from other stuff in your skin.
The goal? To make life easier for millions living with diabetes by offering a painless, easy way to track blood sugar every day.
