"A new method for measuring blood glucose levels, developed at MIT, could save diabetes patients from having to prick their fingers several times a day.
The MIT team used a technique that reveals the chemical composition of tissue by shining near-infrared light on them—and developed a shoebox-sized device that can measure blood glucose levels without any needles.
The researchers found that the measurements from their device were similar to those obtained by commercial continuous glucose monitoring sensors that require a wire to be implanted under the skin. While the device presented in this study is too large to be used as a wearable sensor, the researchers have since developed a wearable version that they are now testing in a small clinical study."
