Wireless Biosensor Data from 26 Subjects During Breathing Tasks

26 subjects performed breath-holding, paced-breathing, and mild hypercapnia tasks while wearing a low-cost multimodal wearable. Thien Nguyen collected this 53.3 MB dataset, which is stored in MAT files and was last updated in May 2026. The data is intended to support research on vital signs and tissue oxygen saturation monitoring.

Use Cases

• Modeling physiological responses to breath-holding based on the described task timings.
• Analyzing patterns during paced-breathing protocols mentioned in the description.
• Studying the effects of mild hypercapnia on vitals and tissue oxygen saturation.
• Developing signal processing methods for multimodal wearable sensor data.

Strengths

• Data from 26 human subjects provides a basis for initial analysis.
• Includes timing markers (stim_new) for three distinct physiological tasks.
• Published in a peer-reviewed journal (Journal of Physics: Photonics, 2026).
• Available under a permissive CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 53.3 MB size suggests a small dataset, potentially limiting model training.
