Industrial Workers Multimodal Physiological Fatigue Dataset — 60,000 Samples

This dataset contains 60,000 balanced samples derived from multimodal physiological and environmental measurements collected from 50 adult industrial workers during occupational activities. The dataset was developed for worker-independent multimodal physiological fatigue detection and contains three fatigue categories: Low, Moderate, and High. It includes physiological measurements, environmental measurements, and derived features used in the associated research study. The data were collected using non-invasive wearable sensing systems from voluntary adult participants. Informed consent was obtained prior to participation. No personally identifiable information was recorded, and the collected data were anonymized prior to analysis. Data collection was conducted under institutional/project authorization and with permission from the participating industrial organization. Access restriction: The participant-level dataset is made available under controlled access because it contains human-participant physiological and environmental measurements. Access is intended for legitimate academic and scientific research purposes and is subject to applicable ethical and institutional requirements. Approved users must not attempt to identify participants, redistribute the dataset, or use the data for purposes outside the approved research use.
