AI Technical Summary
Conventional respiration rate detection techniques require patients to wear expensive and uncomfortable devices like nasal tubes or chest pressure sensors, and existing radar systems are costly due to dedicated hardware, while contact-free methods using Wi-Fi have not effectively addressed simultaneous detection of multiple individuals.
A system and method for respiration rate detection using Wi-Fi CSI from a single COTS device, employing signal processing to clean noisy CSI data, compensate for phase and amplitude errors, and detect multiple respiration rates using FFT and machine learning to distinguish and classify respiratory signals from multiple individuals.
Enables contact-free, cost-effective detection of multiple respiration rates using ubiquitous Wi-Fi infrastructure, overcoming the limitations of conventional methods by reducing hardware costs and improving detection accuracy and efficiency.
