Japanese Scientists Create Smiling Robots Using Living Skin

In July 2024, Minghao Nie from the University of Tokyo demonstrated a significant advancement in robotics by showcasing a face mold covered in human skin tissue. This research, led by Shoji Takeuchi, aims to enhance the realism of robotic faces by incorporating living tissue capable of expressing emotions, such as smiling. The team developed a method to attach live skin cells to robots, creating facial expressions through ligament-like structures. Published in Cell Reports Physical Science, this study highlights the benefits of living tissue, such as energy efficiency and self-repair capabilities, over traditional materials like metals and plastics. Future research will focus on integrating circulatory systems and nerves to further enhance the funct
