| Research Abstract |
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.
