Just in time for tropical holiday vacations, a team of scientists at Northwestern have released a device that can tell you just how much sun is too much. It’s a game-changer if you manage not to lose it on a sandy beach. Holding onto it could be tricky, since the scientists claim it’s the smallest device of its kind in existence.
The device, called “My Skin Track UV,” was officially unveiled at Apple stores on November 13th, but a paper released Wednesday in Science Translational Medicine is the first to provide details on the design and testing of the device. The thumbnail-sized wearable has been lauded because it can track three different types of potentially harmful light and use an app to alert the user if they’re getting toasted. Useful as this is against harmful sun exposure, John Rogers, Ph.D., a biomedical engineering professor at Northwestern who helped design the device, tells Inverse that its real potential lies in its minimalist design, which could reshape the way engineers approach wearables going forward.Read More...
