Project description

The project aims to assess cardio-vascular functions using an in-ear sensor, which has been previously developed in the IN-MONIT BMBF project, to monitor vital parameter signs under clinical conditions i.e. sleep laboratory or operating room. To achieve best results, tests with individual in- ear otoplastic will be performed. Furthermore, the functionality of individual sensors is to be improved- possible application scenarios include emergency use or operation rooms. Using optoelectronic measurement concepts, vital parameters are assessed continuously to monitor cardio-vascular functions. These vital signs include oxygen saturation, heart rate, heart rhythm, heart rate variability, respiratory rate, vessel condition and perfusion. This project further incorporates data analysis, detection of medically relevant parameters, evaluation of parameter dependencies and implementation of methods for risk detection. After being tested successfully, the sensor by CIS GmbH will be applicable in homecare and clinical environment for inconspicuous long term monitoring of patients.

Project partners

The project will be arranged by an interdisciplinary team, consisting of medical and industrial partners.
