十多年前，
麻省理工学院的研究人员把Wi-
Fi变成了一台摄像机。一台能看
穿墙壁、看穿你身体的摄像机。
这项技术被称为RUView。
它是在“倾听”房间本身。
Wi-Fi像无形的雾气一样充满你
家中的空气。无线电信号撞击
你的身体，
又被你的姿势扭曲后反弹回来，
还会被你的呼吸，甚至心跳的
微小颤动所改变。
RU View读取这些畸变，
然后重建出你的样子。
这项技术最初被宣传为老年人防
跌倒的安全设备。现在，这项
技术已经被精细调校到
可以读取你身体的多种
生物特征，包括你的出汗情况、
唤醒与兴奋程度，
以及在不久的将来，
你的脑电波。可怕的是，
任何人都负担得起这项技术。
所需的硬件只是四个
ESP32节点。总共只要48美元。
这个模型有55千字节。
对于实现全面彻底的生物识别监
控来说，这相当便宜。

Over a decade ago, researchers at MIT turned Wi-Fi into a camera. Over a decade ago, researchers at MIT turned Wi-Fi into a camera. A camera that can see through walls and see through your body. The technology is called RU View. It listens to the room itself.
Wi-Fi fills the air inside your home like an invisible fog. The radio signals hit your body and come back warped by your posture, The radio signals hit your body and come back warped by your posture, your breathing, and even the tiny tremor of your heartbeat. RU View reads that distortion and rebuilds you.
RU View reads that distortion and rebuilds you. This technology was originally pitched as a safety device for elderly people to detect falls. Now the tech is fine-tuned enough to read multiple biometrics of your body, including your perspiration, your rate of arousal, and very soon, your brainwaves.
The scary part is anyone can afford this technology. The scary part is anyone can afford this technology. The hardware requires four ESP32 nodes. The model is 55 kilobytes. Pretty inexpensive for total and complete biometric surveillance.
