Studies show early steps toward passive wearable monitoring of glucose, hydration, pulse

By Jonah Comstock 08:14 am June 12, 2014

As the makers of wearable sensors continue to push the boundaries of what those sensors can track, new research suggests that a device worn on the wrist could some day track hydration, pulse, and even blood glucose non-invasively. In two papers published this month in Biomedical Optics Express, the journal of the Optical Society, researchers from around the world used a technique called the...
