美国麻省理工学院(MIT)研究人员日前研发出一个名为“Wi-Vi”的系统,透过该系统,使用者可以利用智能手机发出的Wi-Fi信号,检测到一堵墙背后人们的移动情况。换言之,漫画英雄“超人”用透视眼(X-rayvision)监控坏人的情节将成真。麻省理工学院新闻(MITNews)报导,过去就有科学家尝试打造具有透视墙壁功能的装置,但过去发展出来的系统价格过高、体积过大,且雷达科技所用的部分电磁波只限军方使用。 Researchers at the Massachusetts Institute of Technology (MIT) recently developed a system called Wi-Vi that allows users to utilize Wi-Fi signals from their smartphones and detect a wall behind them People’s movement. In other words, the comic hero “Superman ” X-rayvision to monitor the bad guys plot will come true. MITNews reported that in the past scientists had attempted to create devices with see-through walls, but the systems developed in the past were overpriced and bulky, and some of the electromagnetic waves used by radar technology were for military use only.
