The future of prosthetics could be this brain-controlled bionic leg

October 15, 2013

About a year ago, Zac Vawter climbed all 103 flights of stairs of the Willis Tower in Chicago. On its own, this accomplishment would be pretty unremarkable, but Vawter, who lost his leg four years ago during a motorcycle accident, happened [to] climb more than 2,000 steps while wearing a prosthetic leg. Even crazier yet? Vawter could control this prosthetic leg with his mind, sending instructions from his brain, down through nerves that would communicate with his mechanical limb. (Wired)
