Those little ESP32-CAM boards which mate the WiFi-enabled microcontroller with a small parallel-interface camera module have been with us for years, and while they are undeniably cool to play with, ...

New research shows how the signal from a household WiFi device can be used to monitor heart rate with state-of-the-art ...

Engineers have shown that a technique to measure heart rate via Wi-Fi signals is effective even with the lowest-cost devices - and no wearables needed.

Wi-Fi signals today primarily transmit data. But these signals can also be used for other innovative purposes. For instance, one California-based team has proposed using ambient Wi-Fi signals to ...
