Monitorování vitálních funkcí v automobilech

Abstract

The scope of this thesis is vital sign monitoring in automotive enviroments. The theoretical part is written in a form of a comprehensive research, which summarizes the currently available monitoring methods for non-invasive sensing of vital parameters in automobiles. The aim of the experimental part is to design and implement a pneumatic system that will be integrated into a car seat or seat belt. Experimental part also includes the design and implementation of experimental measurements that determine the accuracy of the designed sensors in a real car application. The content of this thesis is complemented by testing the impact of the type of material, shape, size, encapsulation and location of the sensors, the type of the processing method and various driving conditions in the car. The conclusion of the thesis is dedicated to the statistical evaluation of the results. The comparison of the reference with the processed average heart rate variability extracted from the ballistocardiography (electrocardiography) is used for the statistical evaluation. The complete program including the data processing is written in Matlab.
