Considering that the electrical impedance detection is a soft field measurement, the measurement result is easily affected by the density of the breast structure, and therefore the electrodes are evenly distributed by quadrant to improve the sensitivity of the measurement result to each position in the field.

[0044] Among them, the inner layer of the vest carrier 100 is embedded with two flexible integrated circuit belts, one of which is connected to the 16 electrode rings arranged on the left front carrier 101 through an elastic transmission circuit 300; the other flexible integrated circuit belt is connected to the 16 electrode rings arranged on the right front carrier 102 through an elastic transmission circuit 300.

[0045] The elastic transmission circuit 200 is printed in the inner layer of the vest carrier 100 .

The vest carrier includes an inner layer (facing the user's skin) and an outer layer (the side facing away from the user's skin); the elastic plastic fixing plate 103 is fixed to the outer layer, and the electrode ring is fixedly connected to the inner layer, that is, the electrode ring is arranged between the elastic plastic fixing plate 103 and the inner layer. The elastic plastic fixing plate is used to ensure that the breast of the tester fits the electrode ring.
