Researchers from the University of Utah are developing a system that allows amputees to control a bionic arm using just their thoughts. What’s more, the hand portion of the limb enables them to ‘feel’ objects that are being touched or grasped. Known as the Luke Arm (a tribute to Luke Skywalker’s prosthetic limb), the robotic arm mimics the way a human hand feels different objects by sending signals to the brain. An amputee wearing the arm can sense how hard or soft an object is, letting them understand how best to handle said objects.
