Study summary

The purpose of the study is to determine the precision of an unobtrusive sleep measurement system. The system measures a force sensor signal under the mattress and analyzes sleep quality. The system measures: time in bed, sleep stages, sleep fragmentation, heart rate, respiration rate, sleep related breathing disorders, and limb movements.

What researchers measure

Primary outcomes

  1. Precision of sleep measurement

    The volunteers are measured for seven consecutive days. The precision of the sleep measurements output by the ubobtrusive sleep monitoring system is evaluated by comparing the measurements to polysomnography and actigraphy reference measurements.

    Time frame: 7 days

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 1, 2013, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
