Zac Vawter lost his right leg in a motorcycle accident during 2009. Fast forward to today, you won’t even be able to tell one of his legs isn’t real when you see Zac in pants. Yes, he’s been fitted with the world’s first bionic leg controlled by thought.
This innovative, breakthrough bionic leg was developed at the Rehabilitation Institute of Chicago and was made by possible by rewiring two nerves from what remained of Vawter’s right leg to hamstring muscles. You see, at the top of the bionic leg is a computer with sensors that interact with those nerves, and so when Vawter thinks the actions he wants the leg to perform, the nerves communicate that through the sensors to the computer controlling it, and it performs the desired movement.
