Abstract

The aim of the work was to design pulse sensor which could be applied in a daily human activity. The main pulse measurement principles are presented. Heart rate detection from electrocardiogram was chosen. The reason of this choice was robustness to motion artifacts and low power consumption of the method. Two stage single supply electrocardiogram amplification and analog processing scheme presented. Comparison of the most popular small range wireless data transfer systems and the choice of the optimal one for the sensor was made. Principle of QRS complex discernment from ECG signal presented. Adaptive thresholds were used for QRS complex detection. The principles of adaptive thresholds formation are given. Power consumption minimization possibilities of the sensor discussed. Ill. 7, bibl. 6 (in English; summaries in English, Russian and Lithuanian).
