At its core, the ESP32 chip is not much more than an integrated circuit, a huge mass of transistors sealed inside an epoxy resin package with some leads. Of course, most of us won’t buy discrete ESP32 ...

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.
