| Outline of Final Research Achievements |
To prevent intrauterine fetal death and unexpected neonatal death, we developed and evaluated wearable vital monitor devices and algorithms to continuously monitor fetal / newborn heartbeat signals without stressing mothers, fetuses and neonates. In order to enable continuous heart rate measurement of fetus in late pregnancy without restraining maternal body, we developed a sensor head for acquiring the maternal abdominal wall electrical potential with electrodes attached to pregnant womb band, a small data acquisition device, a fetal heartbeat signal separation algorithm.
Moreover, in order to enable continuous heart rate measurement of neonates without restraining newborn babies under measurement, we clarified conditions of body surface potential signal recording by conductive cloth sheet electrodes. We also developed an algorithm to reduce noise from body surface potential signals by wavelet analysis.
