Summary

Benchmark built to compare wearable cardiovascular monitors on one common, high-rate dataset. All sensors run on one BIOPAC MP160 at 10 kHz, then downsampled to 1 kHz. Stressors change hemodynamics: breath-hold ×4, light exercise ×2, cold pressor ×1 (healthy only), Valsalva ×4, in a Latin-square order.
