In-Ear Acquisition of Vital Signs Discloses New Chances for Preventive Continuous Cardiovascular Monitoring

For preventive continuous cardiovascular monitoring an In-Ear-implemented system will be designed. Using the photoplethysmographic curve a personal In-Ear-sensor measures the physiological parameters. The data are transmitted to a portable data analyser via wireless network, automatically reviewed and in the case of passing a critical value, an alert will be sent out. This In-Ear acquisition is facilitated by a new remission sensor designed by CiS Institut für Mikrosensorik GmbH. This In-Ear sensor is the core component ensuring light emission and reception by planar set-up and therefore, it is capable to use the inherent advantages of this measuring site for vital signs acquisition. Initial results have supported this approach.
