Um artigo científico publicado intitulado “Remotely Mind-controlled Metasurface via Brainwaves” avança o primeiro passo para o controle mental em tempo real, remoto e sem fio de metamateriais.
Quando você pensa em telecinese, usando sua mente para mover objetos à distância, você pensa em pura ficção, como Like Skywalker em Star Wars: Episódio V – O Império Contra-Ataca ou vários personagens de X-Men. No entanto, na verdade é algo em que os cientistas estão trabalhando e, para alguns deles, a tecnologia-chave é algo chamado metamateriais.
In a new paper published in the journal eLight, a joint team of scientists led by Professor Shaobo Qu & Professor Jiafu Wang from Air Force Engineering University and Professor Cheng-Wei Qiu from the National University of Singapore have advanced the first step towards real-time, remote, and wireless mind control of metamaterials. Their paper, titled “Remotely Mind-controlled Metasurface via Brainwaves,” proposes a framework for realizing this goal.
Traditionally, the involvement and participation of humans are usually necessary for many scenarios. A human should control the metasurface with their mind directly. It has also been well established that a human’s brain will generate brainwaves in the process of thinking. The authors theorized that collecting brainwaves and using them as the control signals of metasurfaces would allow the users to control metasurfaces with their minds. It would also improve the response rate of metasurfaces. This development would mark an enormous step towards truly intelligent metasurfaces.
The research team achieved remote control by transmitting brainwaves wirelessly from the user to the controller via Bluetooth. The aim was to utilize the user’s brainwaves to control the EM response of PMs. By taking this route, they demonstrated an RMCM where the user could control the scattering pattern.
The simulated and test results showed that the user’s brainwaves directly controlled the outcome, with a significantly better control rate and switch rate. That indicates that their model was far superior to any existing model or product in the market. Their design can be further customized to improve the accuracy of their equipment.
The research team hopes to combine this with intelligent algorithms and improve the processes in the future. They believe that their work can be readily extended to other mind-controlled functional or multi-functional metasurfaces. It may find applications in areas as diverse as health monitoring, 5G/6G communications, and smart sensors.
