Imagine robots with human-like skin, capable of subtle expressions and self-repair! Researchers at the University of Tokyo are inching closer to this sci-fi vision with a breakthrough technique for attaching living skin cells to robots. The Challenge: Attaching Delicate Skin Previously, attaching real skin to robots proved difficult. The soft, wet tissue was prone to tearing during application. This limited the development of robots that could mimic human expressions or achieve a truly lifelike appearance. A New Approach: Inspired by Nature The Tokyo team, led by Professor Shoji Takeuchi, took inspiration from the structure of human skin ligaments. They created tiny V-shaped anchors on the robot's surface using collagen gel, a protein naturally found in skin. This method provides a "more seamless and durable attachment." Benefits of Living Skin for Robots: Realistic Movement and Expressions: The flexibility of real skin allows for natural-looking movement and potentiall
