The electrode belt 10 comprises an elastic belt 11 and a number of electrically conductive wires 12.
The elastic band 11 is formed by weaving a plurality of knitting yarns 110, and the elastic band 11 is formed in a long band shape as a whole (as shown in fig. 4). In the present embodiment, the braided wire 110 is a non-conductive braided wire having elasticity. It is understood that the elastic band 11 has elasticity as a whole, and can be stretched and deformed by an external force.
