Electronic fetal heart rate (fHR) monitoring is standard in clinical practice to detect deviations from the normal fHR pattern. Typically, an ultrasound (US) transducer, operating in a pulsedwave Doppler mode, measures the periodic motion of the fetal heart, from which the fHR can be derived. However, as the fetus moves through the birth canal, the fetal-heart location (fHL) changes continuously. Consequently, the clinical staff needs to manually track the fHL and reposition the US transducer accordingly. In this research, a new flexible US patch with multiple elements is designed; it allows measuring the fHR over a large range of possible fHLs. Further, a method for dynamic combination of the receiving channels is presented, with the aim of improving the Doppler signal and, therefore, the accuracy of the fHR estimation.
