Researchers at the University of Tokyo have developed an artificial biohybrid hand that utilizes “sushi-like” bundles of thin human skeletal muscle fibers to manipulate a soft robotic exoskeleton. A study recently published in Science Robotics introduces the biohybrid’s multiple muscle tissue actuator (MuMuTA), which powers the device’s fingers to perform human-like movements. The breakthrough holds promising implications for the growing field of biohybrid robotics. The biohybrid hand’s fingers can manipulate objects and perform a “scissors” gesture—a significant improvement over the limited movements displayed by earlier biohybrid models. At approximately 18 cm in length, the MuMuTA-powered robot falls within the smaller...
