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.
Precision of sleep measurement [ Time Frame: 7 days ]
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.
