Resumen de Bionic finger can feel textures
A man who had his lower arm amputated has been able to feel textures once again using a bionic finger. Silvestro Micera at the Swiss Federal Institute of Technology in Lausanne and his team implanted electromechanical sensors in the tip of a prosthetic finger. These sensors deform when touched, sending signals to a computer, which converts them into a sequence of on-off commands. These are then used to stimulate nerves in the upper arm via surgically inserted electrodes
