ER-Rhythm: Coupling Exercise and Respiration Rhythm Using Lightweight COTS RFID

on YouTube ↗06m

" summary

System uses lightweight COTS RFID tags stuck to limbs and chest to extract locomotion and respiration rhythms and then computes locomotor-respiratory coupling. It builds a tag-and-antenna setup with signal fusion across multiple chest tags and exploits the multi-path effect to cut antenna count. Uses a correlation-based approach to couple signals. Evaluation on users during exercise reports LRC estimation accuracy of 92%-95% and shows chest breathing trace recovery despite large torso motion.

2. 0:19Exercise and Respiration Rhythi Scientific body-building is important to avoid physical injuries & visceral organ damage during exercise Monitoring the physiological parameter provides essential guidance for safe and effective exercise • Locomotion and respiration coupling (LRC) is one key parameter . coordination between the exercise locomotion and respiration rhythm • Harmonic LRC reduces energy consumption & promotes
3. 0:59LRC and Its Measurement Common LRC ratios for human doing exercise, e.g., running, cycling and pedaling. LRC 5:1 4:1 3:1 5:2 2:1 5:3 3:2 43 1:1 Current LRC monitoring system is cumbersome with bulky sensors on body.
4. 3:48Respiration Pattern Denoising Remove the noises of the torso movement on the respiration • Periodic torso movement: low-pass filter to remove the high-frequency locomotion changes. • Random torso movement: canceled out by the relative deployment of the RFID tags and antennas
