Love Your FitBit? How About a Skin Patch that Acts like a Lab Test While You Sweat?

In Washington, thanks to researchers at Northwestern University痴 Center for Bio-Integrated Electronics you can now wear a small round skin patch to get back health data that you usually can only get with a lab test ordered by your doctor. Similar to the FitBit idea, the tiny round patch looks like a small bandaid or one of those nicotine patches, but is very high tech in a biochemical way. It analyzes your sweat droplets and sends the data to your smartphone. It can track your electrolytes and alert you before you even feel dehydrated, and interacts with chemicals that change color to let you know your perspiration’s acidity level and even how much chloride, glucose and lactate you have in your body. Once you see the pretty changing colors, use your phone app to take a picture of the patch and it will let you know what the colors mean.
