A 40-year-old Dutchman lost the mobility of his legs in a bicycle accident 12 years ago. He now walks with the help of a walker thanks to a digital bridge between his brain and spinal cord.

The brain-machine system, which has not yet been miniaturized, is still somewhat cumbersome, since the patient needs headphones to send his orders through waves. The next step is to spread this technology to more patients, and for that we need to industrialize it, says one of the researchers.
