Wrist PPG datasets with raw waveforms
Most smartwatches never export the PPG waveform, so public wrist datasets with raw signals are the main way to build and test wearable algorithms. This list only includes datasets where the BVP or PPG waveform itself is downloadable, with heart rate as an extra when present. Check the sampling rate and whether accelerometer data is included if you work on motion artifacts.
