Have you ever forgotten to drink water while playing a sport? Or become so caught up in a good book, you didn’t think to move for hours? Well, not anymore! Researchers at the University of Tokyo in Japan are developing thin, flexible digital patch displays that can stick to your skin. These patches show updates on your health-—everything from heart rate and temperature to the map route for your most recent bike ride!

It took years for the team to figure out how to make flexible and stretchy LED screens, which they call e-skin. Traditional LED technology—like in televisions and cell phones—is difficult to make flexible due to the types of materials needed and added cost. “The ultimate goal of e-skin is to monitor all the different human information easily anywhere and anytime,” says Takao Someya, who worked on the prototypes. They plan to bring e-skin to market within the next three years.
