Researchers at the Ulsan National Institute of Science and Technology, led by Professor Jonghwa Park, have developed electronic skin that can detect changes in both temperature and pressure, thanks to composites made of a polymer as well as reduced graphene oxide. That’s right, this two-play (top for pressure and bottom biochemical signals) electronic skin can detect sensory changes created by water droplets falling at different pressures and temperatures.

The artificial skin could detect a tiny amount of pressure created by a human hair, making it perfect for future caregiver robots. It can also used to monitor pulse pressure by detecting the changes in skin temperature that occur when blood vessels dilate or constrict, when attached to a human wrist.
