The 31-year-old Zac Vawter became the first person in history to use brain-controlled mechanical legs to climb the 103-story Willis Tower in Chicago. According to the Associated Press report, the prosthetic limb uses targeted muscle nerve reinnervation technology (TMR), which converts the electrical signals of the thigh nerve into the control signals of the movement of the prosthesis.
The brain-controlled mechanical legs used by Zac Vawter were developed by the Bionic Medical Center team of the Chicago Institute of Rehabilitation (RIC) to allow users to control the movement of mechanical prosthetics through brain thinking. At present, this technology and products have been used by more than 50 people with disabilities around the world Experiment physically.
According to a RIC spokesperson, the brain-controlled mechanical legs used by Zac Vawter are the latest improved bionic leg products. They are jointly developed by RIC, Vanderbilt University, MIT and URI. The funds are funded by the US Department of Defense Army Remote Provided by medical and advanced technology research centers.
The brain-controlled mechanical legs used by Zac Vawter are worth $ 8 million and weigh 10 pounds. They have two motors that control the knee and ankle joints. Vawter said that this kind of bionic legs is different from ordinary prostheses, which allows him to freely decide the order of steps to climb the stairs, without having to consider whether to leave the left leg or the right leg first.
