Wavelet analysis on FECG detection using two electrodes system device

Fetal electrocardiogram signal detection during pregnancies is very useful in assessing fetal condition. Doppler ultrasound is very common in fetal monitoring. It is safe, but inaccurate, highly sensitive to noise and the success of the measurement depends on the positioning of the probe. Recently, there are many research use noninvasive Ag/Ag Cl electrode in fetal electrocardiogram detection. However it involves large number of electrode during measurement. In addition, complex structures of signal processing are required. A research work has been made on fetal electrocardiogram detection using two electrodes biopotential device without reference electrode. Best possible electrode placement for maximum fetal electrocardiogram waveforms detection has been identified. The signals are successfully detected at 0.028Hz after processed using discrete wavelet analysis for de-noising and continuous wavelet transform for signal detection
