The aim of this sub project is to research a microwave interferometric sensor that enables empathokinesthetic examinations based on the analysis of micro-movements of the body surface. Specifically, the temporal and morphological course of pulse waves, heart sounds and breathing of clothed persons is to be recorded in high resolution via relative distance measurements. The new circuit and algorithmic approaches will enable the recording of cardiovascular activity during simultaneous large-body movements and significantly improve the quality and thus the significance of the measured values.
