Japanese Scientists Create World’s Largest Biohybrid Robot Hand

A team of Japanese researchers has developed the world’s largest biohybrid robot hand, utilizing cultivated human muscle tissues for movement, Anadolu Agency reported. Measuring 18 centimeters (7.08 inches) in length, including a forearm section, the hand features five fingers that can perform complex movements, such as grasping and manipulating small objects.

Unlike previous biohybrid devices limited to single-joint movements and smaller sizes, this innovative design bundles multiple thin strings of muscle tissues in a sushi roll formation, enhancing strength and functionality. This method ensures that nutrients effectively reach each muscle string, allowing for greater movement capabilities.

The research, conducted by scientists at the University of Tokyo and Waseda University, aims to apply this technology to prosthetic hands. Professor Shoji Takeuchi, a mechanical engineering specialist, stated that this advancement could lead to the development of humanlike robots or precision prosthetics. The team’s findings were published in the journal Science Robotics on February 12.
