Real-Time RF Sensing for the Early Identification and Management of Respiratory Health

Real-time Radio Frequency (RF) sensing offers a promising approach for early identification and management of respiratory health. As a non-invasive method, RF sensing uses electromagnetic wave propagation to monitor respiratory patterns without direct contact, providing continuous and real-time data. Utilizing software-defined radio (SDR) technology, we enhance patient comfort and privacy while reducing healthcare facility burdens. This study develops an SDR-based RF sensing system to capture and analyze respiratory activity for early detection of issues such as whooping cough. The system effectively distinguishes between breathing patterns during coughing fits (up to 25 breaths per 30 seconds) and between coughing fits (15-20 breaths per 30 seconds), demonstrating its potential for broad healthcare applications.
