MIT diabetes device monitors glucose with light
Imagine simply shining a light on your skin to determine how much sugar is in your blood. Researchers at MIT are developing a glucose-monitoring device for diabetes patients that may help do away with finger pricks.
By scanning a user's arm or finger with near-infrared light, the device frees users from the necessity of drawing blood, a daily routine for most type 1 diabetes patients.
The laptop-size machine is the result of 15 years of research at the MIT Spectroscopy Lab. It employs Raman spectroscopy, which can determine chemical compounds based on their molecular vibration.
