stretchable sensors

What if wearables like Fitbits and the Apple Watch represent the infancy of on-body health sensors, something we'll one day look back on the way we now look at the clunky, boxy mobile phones of the 1980s? A number of researchers are working on ultrathin, flexible sensors that could be applied to the skin like smart tattoos, or even applied to the surface of organs inside the body to continually monitor vital signs or to deliver time-released drugs.

Researchers at an Australian university have developed stretchable, wearable sensors that could detect both harmful toxic gasses and dangerous UV radiation.
