Japanese Researchers Develop Biohybrid Robot Hand Using Human Muscle Tissue

A team of Japanese researchers has developed the largest-ever biohybrid robot hand, which moves using cultivated human muscle tissue, Kyodo News reported, CE Report quotes Anadolu Agency

The hand, measuring 18 centimeters (7.08 inches) in length, features five fingers capable of complex movements, such as grasping and manipulating small objects. Researchers from the University of Tokyo and Waseda University hope this innovation will advance prosthetic hand technology.

Unlike previous biohybrid devices limited to single-joint movements, the team overcame size and strength limitations by bundling thin muscle tissue strands into a sushi roll-like formation. This design ensures adequate nutrient delivery, allowing the robotic hand to function effectively.

Shoji Takeuchi, a professor at the University of Tokyo, emphasized that this research marks a significant step toward creating humanlike robots and highly precise prosthetic hands.
