Parameter‐Efficient Deep Learning Models for Vital Sign Estimation From PPG

Healthcare Technology Letters, Volume 13, Issue 1, January/December 2026.
This work introduces highly parameter‐efficient, fully convolutional deep learning models for end‐to‐end estimation of heart rate, blood oxygen saturation and respiratory rate directly from PPG signals. The compact models achieve strong cross‐dataset performance and are demonstrated to be practical for on‐device deployment on target devices.

Physiological Reality Verification for Secure Healthcare Multimedia Internet of Things Using Crossmodal Semantic Integrity Learning

International Journal of Distributed Sensor Networks, Volume 2026, Issue 1, 2026.
Modern healthcare multimedia Internet of Things (IoT) systems are systematically integrating face video, respiratory audio, and wearable physiological signals for remote clinical monitoring. However, this evidence can be replayed, spoofed, substituted, or temporally desynchronized before reaching clinical inference. To address these risks, we propose a

Evaluation of the Relationship Between Facial Hue and Blood Pressure Fluctuations in Hemodialysis Patients

International Journal of Biomedical Imaging, Volume 2026, Issue 1, 2026.
Objective In hemodialysis, hypotension may occur due to fluid removal, but traditional intermittent blood pressure measurements risk missing its onset. We are aimed to enabling noninvasive and continuous blood pressure monitoring in patients undergoing hemodialysis based on the spatial features of facial visible images.
