How Bionic Technology Restored This Man's Sense of Touch
Scientists reveal how they helped Dennis Sorensen identify surfaces he was feeling 96% of the time - despite his arm being amputated.
Dennis Sorensen is the first person in the world to sense texture by using a bionic fingertip.
Dennis, who is an amputee, allowed doctors to surgically connect his arm to the bionic finger by using electrodes and targeting his nerves - and it worked.
While conducting blindfolded tests, he could sense when a surface was rough or smooth -and correctly identified the type of surface he was "touching" 96% of the time.
This medical success has major implications for the future of touch-enabled prosthetics.
