Assessment
Primary outcomes As a registry study, collecting 100 cases of measurement raw data from fetuses and maternal bodies who are more than 20 weeks but before delivery, and preparing databases for each group of gestational weeks.
Key secondary outcomes 1)Investigate the equivalence between the analyzed results by the cloud and the monitor 138(stand-alone type-device) which was done clinical trial.
2)Evaluate exploratory the potential of clinical application as a fetal ECG, through extracting and analyzing abdominal wall induced fetal electrocardiogram heart rate signal from collected measurement raw data by new fetal heart rate extraction program.
3)When concluded to recognize the potential of clinical application as a fetal ECG, propose the standard value of fetal electrocardiogram, based on data from this study.

Other
Other related information 1) To hospital visitor of prenatal checkup, make an explanation of the present study, obtain the consent document.
2) Check whether to meet the selection criteria, perform patient registration.
3) Before or after a prenatal checkup, a pregnant woman is in a state of supine or lying position, using a gel sheet for attachment of dish-shaped electrode code, attach on the abdominal wall maximum 13 electrode codes and an electrode code with an earth for body.
4) At the time of measurement by the test equipment, using the birth surveillance equipment (ultrasonic Doppler method) to observe the condition of fetus, simultaneously collect the data.
5) Measurement must be done more than 10 minutes (About 10 minutes to 20 minutes).
