Japanese scientists graft living skin onto ‘smiling’ robot

Researchers say breakthrough could pave the way to realistic humanoids in the future.
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.
