This paper lays emphasis on heartbeat monitoring. The polyvinylidene difluoride (PVDF) material is used as the sensor for signal acquisition. There are two crucial subjects in this paper that shall be solved for heart rate calculation. First, the difference in signal amplitude shall be overcome (each analyte has a different heartbeat amplitude or intensity), so that the algorithm can calculate the heart rate effectively. Secondly, the difference in signal frequency or cycle is overcome (each analyte has a different heart rate or cycle), so that the accuracy of calculated heart rate is increased. Finally, the signal acquisition makes noise, which influences the calculation of heartbeat. The signal shall be preprocessed to remove the noise. Added to this, the sensor is placed in different positions, and the algorithm shall identify the signal as heartbeat signal or other signals, which contributes to calculating the heart rate rapidly. Our algorithm can calculate the heart rate effectively when the sensor is placed in different positions (chest and wrist) and overcome the effect of different signal cycle lengths.
