Abstract

The theme of this bachelor thesis is Design of Common ECG/PPG electrode. The first part is focused on the theoretical analysis of Electrocardiography and Photopletysmography. Next part of this thesis is a search, which handles various studies associated with these methods of measuring biological signals. The practical part is focused on design and manufacture of common electrode. The aim of this work is to enable the common sensing electrical activity of heart and volume changes in the tissue. For measuring ECG was used two little metal squares and for sensing PPG was used reflective type sensor. For merger both types of sensor was used textile rubber belt, which allow different placement of sensors on the body. The main contribution of this work is to test and evaluate different sensor location on the body, selection of the most appropriate and the chance to shoot together both ECG and PPG signals and determine their measured results.
