- Pulse-Fi system uses WiFi signals to measure heart rate with clinical-level accuracy without wearables.
- Works with ultra-low-cost WiFi devices like ESP32 ($5-$10) and Raspberry Pi (~$30).
- Effective up to 10 feet away and in various body positions (sitting, standing, lying, walking).
- Machine learning algorithm filters noise to detect faint heartbeat signals.
- Dataset created using ESP32 and oximeter for training the neural network.
- Future research aims to detect breathing rate and conditions like sleep apnea.
