Sleep Analyzer records and computes your health parameters in real time to understand your sleep and deliver accurate health data. Heart rate Each time your heart beats, it propels a mechanical wave through your body, which is measured continuously with high precision by the pneumatic sensor. Breathing Sleep Analyzer filters your motion signal to extract your breathing rate throughout the night. Movement The movements of your body generate mechanical waves, which are captured by the pneumatic sensor. Carefully calibrated. Extensively tested Sleep Analyzer has been developed in collaboration with sleep physicians from Hôpital Béclère in Paris and extensively tested against data obtained by polysomnography (PSG) analysis, the gold standard of sleep diagnostics.
