L’exosquelette is an exoskeleton that can be controlled by the brain. It’s the first exoskeleton which works with implants, allowing a fully paralysed patient to move all four limbs. This is an example of a brain-computer interface (BCI). The system uses an implant in the brain, the wimagine. This was designed to intercept electric brain activity using 64 electrodes, and to wirelessly send it to the exoskeleton. The sensors are surgically placed inside both sides of the sk ull, on the surface of the brain. These are converted into the skeleton’s movements. With a machine-learning algorithm, the movements keep improving. So far there is no comparable exoskeleton which is controlled by wireless implants in the brain.
