Jellyfish-inspired e-skin glows when it's in 'pain'

Artificial skin stands to have a variety uses, with potential applications in everything from robots to prosthetics. And in recent years, researchers have been able to instill sensory perception, like touch and pressure, into artificial skin. However, while those sorts of senses will be incredibly important in engineered skin, they've so far been rather limited. For example, while current versions can be quite sensitive to light touch, they don't fare so well with high pressures that could cause damage. So researchers at the Huazhong University of Science and Technology in China set out to fix that problem and they drew their inspiration from jellyfish.
