Scientists at the University of Tokyo have developed a breakthrough robot face covered with living skin that can heal itself and even form a smiling expression, paving the way for more human-like cyborgs. The skin, created from human cells on a collagen base, is a key step towards robots that can heal and interact with humans in a more natural way. This living skin technology has potential applications in healthcare, service, and companion robots that require human-like functions. The lab-grown skin, attached to a robot face, can repair itself and move with the mechanical components without tearing. While still not identical to human skin, researchers are working on incorporating additional features like sweat glands and nerves to make it even more realistic. The technology also has implications for the cosmetics industry, as the skin can replicate expression wrinkles. The team aims to further develop the living skin for use in robots within the next decade.
