Researchers are exploring the potential of using WiFi signals as sonar, enabling AI-powered detection of movements, gestures, and even breathing rates. This technology, known as WiFi sonar, works by analyzing subtle changes in signal patterns when interacting with objects or people. With the help of machine learning algorithms, AI can learn to recognize these patterns and "see" through walls without cameras or sensors.

While this tech has impressive applications in healthcare, security, and home automation, it also raises concerns about privacy and security. As WiFi standards improve, accuracy will increase, but striking a balance between innovation and user privacy will be crucial.
