Brief summary

Validation of two devices with optical sensor in healthy participants and patients with sleep wake disorders.

Detailed description

The objective of this study is to evaluate and optimize a method of detecting sleep and sleep stages based on a new algorithm combining actigraphy and heart rate variability (measured by optical analysis of the pulse wave) to determine sleep architecture (segmented into three phases: WAKE, REM and NREM) with high accuracy compared to the gold standard polysomnography.
