Radar Tech to Monitor Sleep

Science Innovations

The scientists at ETH Zurich have developed a convenient device Sleepiz, enabling continuous monitoring of the sleep of a patient by the bedside. Sleep apnoea (pauses in breathing or periods of shallow breathing during sleep) can cause depression or other psychological issues, obesity, impotence, diabetes, high BP, strokes, and heart attacks. The palm-sized device is put on the bedside table. It uses low power electromagnetic waves to detect body movements based on the Doppler radar effect. Coupled with advanced machine learning algorithms, Sleepiz achieves clinical-grade assessment in analysing pulse rate, breathing rate, and body movement, even when the patient wears pyjamas and is covered by a blanket. The data gathered is simultaneously transferred to the ETH Zurich cloud platform. Automated reports and trend analyses help doctors take the next course of action faster.
