Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The objective of this study is to collect data comparing the Zensorium Biosensing Wearable Device (zBWD) to polysomnography (PSG) in individuals with Sleep-Wake Disorders. zBWD is similar to other wearable devices (e.g., fitbit and apple watch) that use an optical light sensor and Tri-axis Accelerometer to record steps, activity, sleep/awake states, sleep staging, and statistical variation of pulse pressure to track stress. Specifically, it is designed to report sleep duration, non-rapid eye movement (NREM) and REM sleep duration. However, zBWD has not been validated against PSG for sleep tracking in healthy controls or in individuals with sleep-wake disorders.
