In-ear sensor for monitoring vital parameters and biofeedback therapy
The basis of the biofeedback system is the analysis of vital parameters measured in the external auditory canal. Sensors determine the optical density of the rhythmically perfused tissue. This allows conclusions to be drawn about local blood flow and the systems regulating blood flow. These include, above all, cardiac activity, respiration and thermoregulation, which in turn are under the influence of the autonomic nervous system
