This project has aimed to develop new electrodes to measure fetal electrocardiogram signals in specific situations, such as measuring extremely-low-voltage fetal ECG via the abdominal walls of pregnant mothers, who are receiving home care in remote places where shielded rooms are not available. The voltage of the specific measurement is set less than 10 u V, which is significantly low, thus it requires new technology to perform the task and obtain accurate results.Among various materials, a special gel was chosen as the most optimal material for creating electrode; then the optimal size, figure, and proportion are calculated. Although single-sheeted electrode was assumed most optimal, as the result, a set of three sheets has been found most optimal.

该项目旨在开发新的电极，以在特定情况下测量胎儿心电图信号，例如通过孕妇的腹壁测量极低电压的胎儿心电图，这些孕妇在没有屏蔽室的偏远地区接受家庭护理。特定测量的电压设置为低于10 uV，这是非常低的，因此需要新的技术来执行任务并获得准确的结果。在各种材料中，选择了一种特殊的凝胶作为制作电极的最佳材料;然后计算最佳尺寸，形状和比例。虽然单片电极被认为是最佳的，结果，一组三片已被发现是最佳的。
