🦾 Biohybrid Robot Hand Powered by Human Muscles

Japanese scientists at the University of Tokyo and Waseda University have engineered a biohybrid robot hand that utilizes lab-grown human muscle tissue for movement. This innovative 18-centimeter hand features independently moving fingers, powered by Multiple Muscle Tissue Actuators (MuMuTAs), which are bundled strands of cultured muscle. The hand can perform various gestures and manipulate small objects while submerged in a nutrient solution, demonstrating human-like muscle fatigue and recovery. This research signifies a significant step towards advanced prosthetics, more humanlike robots, and improved drug testing models by merging biological and mechanical systems.
