摘要

Abstract

The power of controlling objects with mind has captivated a popular fascination to human beings. One possible path is to employ brain signal collecting technologies together with emerging programmable metasurfaces (PM)

whose functions or operating modes can be switched or customized via on-site programming or pre-defined software. Nevertheless

most of existing PMs are wire-connected to users

manually-controlled and not real-time. Here

we propose the concept of remotely mind-controlled metasurface (RMCM) via brainwaves. Rather than DC voltage from power supply or AC voltages from signal generators

the metasurface is controlled by brainwaves collected in real time and transmitted wirelessly from the user. As an example

we demonstrated a RMCM whose scattering pattern can be altered dynamically according to the user's brain waves via Bluetooth. The attention intensity information is extracted as the control signal and a mapping between attention intensity and scattering pattern of the metasurface is established.With such a framework

we experimentally demonstrated and verified a prototype of such metasurface system which can be remotely controlled by the user to modify its scattering pattern. This work paves a new way to intelligent metasurfaces and may find applications in health monitoring

5G/6G communications

smart sensors

etc.
