The world’s first fully mind-controlled synthetic leg goes for a stroll

Connected to leg of its owner by two nerves and computer sensors, this bionic leg works in exactly the same manner as a natural leg. With an error rate of just 1.8%, it’s as close to a flawless mind-controlled limb as science has gotten yet. Created by the Chicago Center for Bionic Medicine, the leg is just the latest in the line of future prosthetics.
