Researchers at Tokyo University have developed a groundbreaking technology that allows humanoid robots to have fleshy faces capable of smiling. Through the use of engineered living skin tissue and human-like ligaments, the robots now have a more natural appearance. This innovative approach not only enhances the robots' lifelikeness but also has potential applications in the cosmetics and plastic surgery industries for humans. By incorporating self-healing capabilities, sensors, pores, sweat glands, and fat, the robots could become even more realistic in the future. Additionally, the researchers aim to further improve the robots' movements by incorporating cultured muscle tissue. This advancement in robotics opens up new possibilities for creating more humanlike robots and gaining insights into human skin biology. Overall, the development of living skin for robots marks a significant milestone in the field of robotics and bioengineering.
