Within the Carnegie Mellon University, located in Pennsylvania (USA), researchers managed to develop a very innovative method. The technology presented is capable of detecting the three-dimensional shape and all the movements of the human body in any environment through Wi-Fi. It would be as if you could see through walls.

The technology developed uses the DensePose – a pixel mapping system on the surface of the human body. It would be like mapping a photo, for example. Employees from Facebook’s artificial intelligence division and researchers from London worked on this research.
New technology can see through walls with Wi-Fi
The article showing the results of the experiment able to see through the paredes was recently published on arXiv (prepress server). To capture the signals, a deep neural network capable of interpreting the sent and received Wi-Fi signals was mapped. They are able to draw the exact coordinates of the human body.
It is worth noting that scientists have been working for a long time on how to be able to see through walls. Even in 2013, a team from the Massachusetts Institute of Technology (MIT-USA) achieved a similar result with cell phone signals. In 2018, another MIT research used Wi-Fi to detect humans in another room and translate the movements they made.
According to the recently released article, scientists believe that Wi-Fi routers may, in the future, replace normal RGB cameras. Although the view is not detailed, it is possible to perceive the presence of people and even identify some of the movements and trajectories.
The use of the internet signal is very useful from the point of view that does not depend on lighting and difficulties with lenses. These points are challenges that traditional and even the most modern cameras continue to face in terms of security.
“In fact, most families in developed countries already have Wi-Fi at home, and this technology can be scaled to monitor the well-being of older people or just to identify suspicious behaviors in the home,” say the researchers about the new see-through-walls experiment.
