The position most easily detecting the signal of uterine electromyography is located near the navel midline. Therefore, the electrode layout can be selected according to the value of N, if N = 16, the electrode layout selects all electrodes from the 3rd row to the 6th row, if N = 8, the electrode layout selects eight electrodes from the 3rd row to the 6th row, the 2nd column and the 3rd column, and if N = 4, the electrode layout selects four electrodes from the 3rd row and the 5th row, the 2nd column and the 3rd column.
