The incredible invention will track heart rate and a person's general health - and could leave current exercise and fitness apps irrelevant.

Researchers in Japan who have developed the 'smart skin' say it could be used in the future to monitor blood oxygen levels, heart rate and the body's overall performance.

Scientists from the University of Tokyo have described the e-skin as a "ultra-thin, ultra-flexible, protective layers."

Researchers have used polymer light-emitting diodes (PLEDs) and organic photodetectors (OPDs) which are thin enough to be attached to the skin and flexible to detect and respond to any body movement.
