A fetal monitor assesses how your baby is handling the stresses of labor by gauging the response of its heartbeat to the contractions of the uterus.

Fetal oxygen machines are designed to be used with traditional electronic monitors, which track heart rate to determine whether the fetus is experiencing stress or lacking oxygen.

This paper introduces a new type of portable and no invasive fetal heart rate monitor which based on 32-bit ARM embedded microprocessor LPC2290 and MEMS acceleration transducer.
