| Summary:
Brain-computer interfaces (BCIs), invasive or non-invasive, have projected
unparalleled vision and promise for assisting patients in need to better their
interaction with the surroundings. Inspired by the BCI-based rehabilitation
technologies for nerve-system impairments and amputation, we propose an
electromagnetic brain-computer-metasurface (EBCM) paradigm, regulated by
human’s cognition by brain signals directly and non-invasively. We
experimentally show that our EBCM platform can translate human’s mind from
evoked potentials of P300-based electroencephalography to digital coding
information in the electromagnetic domain non-invasively, which can be further
processed and transported by an information metasurface in automated and
wireless fashions. Directly wireless communications of the human minds are
performed between two EBCM operators with accurate text transmissions.
Moreover, several other proof-of-concept mind-control schemes are presented
using the same EBCM platform, exhibiting flexibly-customized capabilities of
information processing and synthesis like visual-beam scanning, wave
modulations, and pattern encoding.
