ABSTRACT
The growing demand for continuous health monitoring in clinical, occupational, and sports settings is driving the development of wearable systems capable of reliably estimating cardiorespiratory parameters outside traditional laboratory environments. However, translating raw sensor data into accurate heart rate (HR) and respiratory rate (RR) estimates requires careful algorithm design, robust signal processing, and rigorous metrological validation, particularly in the presence of motion artifacts and signal quality degradation.
This tutorial presents a comprehensive framework for the design and validation of wearable systems for cardiorespiratory monitoring systems. Starting from sensor selection and characterization, it covers the full signal processing pipeline, HR and RR extraction via both time-domain peak detection and frequency-domain windowed analysis, and motion artifact mitigation through multi-sensor fusion and signal quality index evaluation. Practical examples drawn from real acquisition campaigns across different activity levels are also discussed.
The tutorial aims to provide attendees with actionable guidelines for developing and benchmarking wearable cardiorespiratory systems, addressing the trade-offs between algorithm complexity, temporal resolution, and robustness to real-world disturbances.
