Motion and heart rate from a wrist-worn wearable and labeled sleep from polysomnography

This project contains acceleration (in units of g ) and heart rate (bpm,measured from photoplethysmography) recorded from the Apple Watch, as well aslabeled sleep scored from gold-standard polysomnography. Data were collectedat the University of Michigan from June 2017 to March 2019, and there are 31subjects in total. Code to read and process these files is available onGitHub. The paper corresponding to the work is Walch et al., "Sleep stageprediction with raw acceleration and photoplethysmography heart rate dataderived from a consumer wearable device", SLEEP (2019).
