You’d know someone’s health just by looking at them.
Electronic skins might not only detect health troubles in the near future, but display them for the world to see. University of Tokyo researchers have developed an e-skin that can measure vital signs like your heartbeat and display them in real time on a skin display. The design blends a breathable nanomesh electrode and stretchable wiring with an array of micro LEDs that can output basic images bending with your body. Others know right away if you need help — they’d just have to look at your hand (or anywhere else the sensor works) to get an idea of what’s wrong. The sensor can pair with a smartphone and transmit its info to the cloud, too.
