Optical blood pressure monitor
Diseases of the cardiovascular system are among the most frequent causes of death in industrial nations.
An important indicator of this is hypertension, which is currently diagnosed and monitored by means of
mechanical pressure cuffs applied at the upper arm. This unpleasant method restricts the patient's
everyday life and provides only comparatively few punctual measurements. An optical sensor that is
integrated into an earmould and can evaluate the blood pressure changes of each individual heartbeat
can provide a remedy. In addition to other important parameters such as heart rate, heart rate
variability and blood oxygen saturation, the CiS Research Institute has now also succeeded in developing
solid algorithms for evaluating changes in blood pressure. The patented procedure is based solely on the
data of the optical in-the-ear ear sensor and thus offers an everyday possibility for monitoring important
vital parameters.
The CiS Research Institute develops and manufactures silicon sensors for numerous fields of application.
Together with industrial partners from the hearing aid industry, universal and individual earmoulds with
integrated optical sensor assemblies have been developed. The hearing ability is not restricted and a
high wearing comfort is achieved. CiS offers the production of such prototypes up to small series as well
as development and transfer services for the integration of the sensor assembly into customer-specific
medical products and applications.
