mmWave Radar Technology

The Science Behind Contact-Free Monitoring

Our device uses Texas Instruments IWR6843 mmWave radar to transmit 60-64 GHz radio waves. Reflected signals carry phase modulations caused by chest wall movements during breathing and heartbeat. Through sophisticated signal processing—FFT, clutter removal, phase unwrapping, bandpass filtering—we extract vital signs with clinical-grade accuracy.
