Electronic skins can already react to touch, but they’re not much good at reacting to the jabs and burns that cause pain. That’s a problem for prosthetics and robots that are supposed to have human-like responses. They may be more sensitive in the future, though. RMIT University researchers have developed an artificial skin (via SciTechDaily) that reacts to pain much like humans do. It would provide “near-instant” feedback if pressure and temperatures hit levels that would make someone yelp.
The wearable prototype is made of stretchable, extremely thin electronics (oxides and biocompatible silicone) with pressure sensing, temperature-reactive coatings and brainlike memory cells. It’s subtle enough to communicate the difference between gently poking yourself with a pin versus a painful jab, researcher Md Ataur Rahman said. The design mimics the neurons, neural pathways and receptors that guide human senses.
