Worldwide, research and industry are working on health wearables, mobile and barely visible systems, which are capable of recording, analyzing and providing vital parameters to medical professionals for evaluation, under day-to-day conditions and with a high degree of comfort for the patient.
The continuous recording of peripheral photoplethysmograms provides further valuable information on human health. In addition to the pulse rate and arterial oxygen saturation, this includes the heart rate variability, the respiratory frequency as well as data on arterial stiffness and signs of rising or falling blood pressure.
The tiny vital signs sensors developed by CiS are placed in the acoustic meatus and are individually adapted to the patient with a high level of comfort. The special place of measurement enables the recording of high quality signals and a detailed shape analysis of pulse waves followed by the transformation of the PPG into an image of the peripheral blood pressure wave.
