Direct wireless communication of human minds via non-invasive brain-computer-metasurface platform

Recently, coding metasurfaces incorporating active components have enabled real-time and programmable controls over EM functionalities, which used to be static or quite limited in conventional passive counterparts. However, these kinds of metasurfaces still require manual operation. To directly inspect and distinguish the human’s will, the brain-computer interface (BCI) is presented to establish communication between the brain and devices, offering a new control perspective for programmable metasurfaces. By collecting brain signals, a BCI can decode the operator’s intentions and send commands to the controlled objects, without any requirement for the operator’s muscle activity.
