Summary

Source dataset for τ-Ring: A Dataset and Toolkit for Multiparameter Cardiovascular Physiology Sensing on Rings (Tang et al., Tsinghua, 2025, arXiv:2505.04172) and reused by the CITRUS thesis for ring-side motion experiments. Two custom ring prototypes (reflective / transmissive optical paths), IR+red PPG at 100 Hz, 3-axis accel, 34 subjects, ground truth from oximeter/resp-band/BP-cuff/ECG-patch depending on sub-cohort.
