Respiration Measurement Using Sensors


Most of the time, breathing is not continuously monitored in nursing or in hospital, especially during sleep. As a result, a change for the worse in the patient's condition is noticed late. Continuous recording of respiratory parameters with discreet, external sensors can be a solution. The recorded respiratory data provide information about the general state of health and can be used for an early alarm in case of deterioration. The measurement is enabled by a radar that measures without contact and is therefore particularly user-friendly and hygienic.

Sleep problems can become a health risk. This is because poor sleep increases the risk of daytime sleepiness, for example. This is especially the case with breathing-related sleep problems, such as chronic obstructive pulmonary disease (COPD) or sleep apnea. The nocturnal breathing pauses in sleep apnea also carry a high risk of secondary diseases. The contactless respiratory monitoring, developed at the Oldenburg Branch for Hearing, Speech and Audio Technology HSA, is aimed at companies in the consumer health sector as well as markets for medical devices for vital data recording. In our Connected Health work area, we develop solutions for health services that can be used flexibly from anywhere and function contactless.

The radar is adjusted once and then records the patient's breathing without contact.
The respiratory data measured in the process allow conclusions about the state of health.
A recording of the respiration data also works even if the person turns and moves during sleep.

Further information



Did you sleep well last night? This question concerns everyone, because sleep disorders affect health in the long term. That's why we are working on a multi-sensor system close to the ear that records sleep behavior comfortably at home.


Connected Health

The work area Connected Health dedicates its research and development activities to sensor-based health systems that can be deployed flexibly and without clinical infrastructure.


Oldenburg Branch for Hearing, Speech and Audio Technology HSA

The objective of the Oldenburg Branch for Hearing, Speech and Audio Technology HSA of the Fraunhofer Institute for Digital Media Technology IDMT is to transfer scientific findings related to hearing perception and man-machine interaction into technological applications.

The Oldenburg Branch for Hearing, Speech and Audio Technology HSA is funded in the program »Vorab« by the Lower Saxony Ministry of Science and Culture (MWK) and the Volkswagen Foundation for its further development.

Mobile Neurotechnologies

The group »Mobile Neurotechnologies« is working on discreet EEG systems for the analysis of brain activity - e.g. for safe workplace design or for use in health applications.
