Abstract
A system for monitoring the fetal size of an expectant mother comprises an acoustic sensor for positioning over the belly of the expectant mother, the acoustic sensor configured to receive an acoustic signal generated by the fetal heartbeat and to generate a sensor output signal. A fetal size is determined from a sensor output signal strength. This system is based on the realization that certain acoustic signals generated by the fetal heart beat are strongly correlated with the fetus size.
