Within the BedSense project a newly developed, extremely sensitive pressure sensor is placed under the mattress to monitor even the smallest change in pressure. This contactless bedsensor is used to detect presence, movements, breathing rate and heart rate reliably. Benefit of placing the sensor under the mattress is that the existing mattress can be used and that users, also after months of use, do not feel the sensor at all.
Raw information is stored in high-resolution on SD-card. At the moment the functional prototype is validated at Kempenhaeghe, the leading sleep centre in the Netherlands for sleep disorders and epilepsy. BedSense measurements are compared to the golden standard: the Kempenhaeghe polysomnography system.
These measurements will help to refine the various signal processing algorithms for automatic feature extraction for specific diseases and patient groups.
Current focus is on three use cases: effectiveness of sleep interventions in the home environment (like OSA), sleep quality for Parkinson patients and epilepsy detection.
