Contactless breathing monitoring with radar technology
Long-term sleep problems are serious. Among other things, it increases the risk of daytime sleepiness. This is especially the case with breathing-related sleep problems, such as chronic obstructive pulmonary disease (COPD), which is associated with narrowing (obstruction) of the airways. In this case, monitoring breathing during sleep can be crucial. Continuous monitoring of respiratory parameters can also detect a worsening of the patient's condition at an early stage in hospital and nursing care. However, this is not always possible due to the high effort involved. Moreover, the sensors, which have to be worn directly on the body, are often perceived as annoying.
In their project »REMUS« (Respiration Measurement Using Sensors), the experts at Fraunhofer IDMT in Oldenburg are working on a contactless, hygienic and easy-to-set-up monitoring of respiration and other vital parameters, such as heart rate.
