Checking your blood sugar several times a day is one of the most frustrating parts of managing diabetes. You have to prick your finger, draw blood, and repeat the whole process multiple times. MIT researchers might have just found a way to make that a thing of the past.
Researchers at MIT have developed a shoebox-sized device that can measure blood glucose levels without any needles. It uses a light-based technique called Raman spectroscopy, which works by shining near-infrared light on your skin and analyzing how that light interacts with the molecules in your tissue.

The device picks up glucose signals from just below the skin’s surface, no wire insertions or finger pricks required.
So how accurate is it?
Pretty accurate, as
