Effective fetal monitoring is an important guarantee for fetal health and early\ntreatment. Fetal movement is one of critical indicators of fetal monitoring,\nwhich plays an important role in fetal health. Counting the number of fetal\nmovement by pregnant women is a traditional method for long-term monitoring.\nHowever, there are many defects in pregnant womenâ??s feeling count,\nwhich cannot meet the accurate requirements of modern perinatal medicine.\nWith the rapid development of biological and electronic technology, various\nsensors are used to probe the fetal dynamic monitoring, but not on fetal\nmovement. This research proposes a monitoring method for fetal movement\nvia three electrodes. Briefly: first, three electrodes are used to extract electrical\nsignals in the abdomen of pregnant women; second, these signals are amplified\nand filtered; third, A/D converter with microprocessor is used to make\nanalog digital conversion, which can be stored in the SD card under the control\nof the microprocessor; finally, the SD card data are processed by computer\nsoftware and the fetal movement information is analyzed.
