Japanese scientists graft living skin onto 'smiling' robot

Tokyo, Japan – Japanese scientists have developed a technique to attach self-healing, living skin to a robot face and make it "smile". The scientists, led by professor Shoji Takeuchi at the University of Tokyo's Biohybrid Systems Laboratory, connected cultured skin tissue in the likeness of a human face to an actuator – an external mechanical device – using "anchors" that mimic skin ligaments. In a video released by the team, the scientists can be seen manipulating the skin into a smile without causing the tissue to bunch, tear or get stuck in place. Previous efforts to attach tissue made from human cells to a solid surface would result in the skin being damaged when in motion. While Takeuchi's fleshy pink blob bears greater resemblance to a children's animated character than a human face, researchers hope the breakthrough will pave the way to realistic humanoids in the future.
