Abstract

We have developed a wearable and wireless near-infrared spectroscopy (NIRS) device to monitor fetal heart rate and heart rate variability. The device was applied to measure NIRS signals in 12 pregnant volunteers in their second and third trimesters. The fetal heart rate calculated from these NIRS signals is consistent with the fetal heart rate measured from a continuous Doppler ultrasound device. This result suggests a potential of a wireless, wearable, and affordable device to monitor fetal well-being continuously. If successful, this device will be extremely helpful to low-income populations who have limited access to modern healthcare.
