Special Issue Information

Dear Colleagues,

The global burden of non-communicable disease, an ageing population, and sustained pressure on hospital-based care have collectively accelerated interest in continuous physiological monitoring beyond traditional clinical settings. Wearable sensor platforms spanning photoplethysmographic, electrocardiographic, impedance-based, and electromyographic modalities now offer the prospect of longitudinal, unobtrusive data acquisition in ambulatory and community environments. The convergence of advances in microelectronics, wireless communication, and machine learning has substantially expanded both the range of measurable physiological parameters and the analytical depth with which resulting data streams may be interrogated. Yet the translation of this potential into validated clinical practice remains incomplete. Real-world deployment introduces persistent technical and methodological challenges

This Special Issue of Sensors aims to present and disseminate the most recent advances related to wearable physiological monitoring, spanning continuous cardiovascular and respiratory monitoring, chronic disease management, signal quality and data trustworthiness, and the clinical validation of AI-assisted interpretation. We consider contributions addressing original empirical research, validation studies, methodological frameworks, and critical reviews that advance the evidence base for wearable sensor deployment in real-world clinical and community contexts.

Potential topics include but are not limited to:

  • Continuous Cardiovascular & Respiratory Monitoring Beyond the Hospital;
  • Wearables in Chronic Disease Management: Evidence from the Field;
  • Signal Quality, Artefact Rejection & Data Trustworthiness in Real-World Wearables;
  • AI-Assisted Interpretation of Wearable Data: Clinical Validation Challenges.

This paper presents research on a Predictive and Uncertainty Assessment Framework (PUAF), providing a comparative analysis of two prominent methods, Monte Carlo (MC) Dropout and Bootstrap-based models, used in uncertainty estimation techniques of Neural Network predictions of human activity recognition using accelerometer data. Unlike traditional studies that optimize classification accuracy, this work emphasizes uncertainty quantification to enhance model reliability, particularly for critical health-related activities. Among the five activity classes of Sit, Sleep, Walk, Cough and Fall, this work concentrates on the Cough and Fall cases. The study exploits acceleration data from a wearable device positioned on the user’s chest, with features derived from three-axis motion measurements. Synthetic datasets are generated by systematically introducing noise variations, added to the original dataset across all axes, to assess robustness under real-world conditions. Each uncertainty estimation method estimates the probabilities for the five different classes along with the corresponding 95% confidence intervals to quantify the prediction uncertainty. A detailed evaluation is conducted by analyzing the average width of these confidence intervals across different noise levels, identifying the most reliable feature and model combination. Both the MC Dropout and Bootstrap enhance model robustness and uncertainty awareness under noisy sensor conditions. The MC Dropout provides sharper and more sensitive uncertainty estimates, while the Bootstrap yields more stable and better-calibrated predictions. The evaluation using the proposed PUAF demonstrates that each method offers distinct advantages, highlighting the importance of uncertainty quantification for reliable wearable-based HAR systems.
