TOKYO, Feb. 16 -- A research team from the University of Tokyo and has unveiled the largest-ever "biohybrid" hand, featuring parts made from cultivated human tissue.

The team, led by Xinzhu Ren and Shoji Takeuchi from the University of Tokyo's Graduate School of Information Science and Technology, and Yuya Morimoto from Waseda University's Faculty of Science and Engineering, has developed a robotic hand that moves using living muscle tissue.

The hand measures 18cm long, with a 6cm palm size - described as roughly the size of a newborn's hand - and five fingers capable of independent motion.

The team's breakthrough was published in the February 2025 online edition of Science Robotics, a peer-reviewed journal that publishes cutting-edge re...
