A research team from the University of Science and Technology of China (USTC) has unveiled a groundbreaking biomimetic prosthetic hand with high dexterity, which is capable of combing hair, operating smartphones, and even performing intricate sign language gestures. The lightweight prosthetic device, which replicates the functionality of a human hand, highlights a significant advancement in prosthetics and humanoid robots, offering hope to millions of amputees worldwide. The study was published in Nature Communications, the USTC said on its official website. A leap forward in prosthetics The human hand, with its 23 degrees of freedom (DOFs) -- the number of independent movements it can perform -- is a marvel of natural engineering, contributing to 54 percent of the body's overall functional movements despite weighing only about one-150th of the body's weight. Traditional prosthetic hands, often powered by motors, struggle to balance weight and functionality. Most weigh more than 0.4 ki
