A team at the École Polytechnique Fédérale de Lausanne in Switzerland have developed a bionic finger which has been surgically connected to the nerves of a man who had his lower arm amputated, allowing him to regain his sense of texture.
The bionic finger contains electromechanical sensors that deform when touched, allowing Dennis Sørensen to feel sensation of texture where the index finger of his amputated arm had been. He said: “I could tell the difference between rough and smooth – it was amazing.”
