Furthermore, the foam has good flexibility and can be bent freely, so that the electrode paste can be flatly pasted on any part of a human body, and the problem of poor electrode contact caused by pasting and warping can be avoided. However, the present invention is not limited to this.
In the embodiment, the portable three-conductive electrode paste further includes a PET layer 6 disposed between the surface substrate 4 and the circuit board assembly 3, and the three metal electrodes 5 are electrically connected to the circuit board assembly 3 by penetrating through the PET layer 6.
