And, when the ambient humidity is reduced, the moisture-conductive yarn 200 can release the absorbed body fluid, ensuring that the conductive yarn 100 can be in a wet environment for a longer time, and the fabric electrode device can maintain a higher signal transmission quality for a longer time. In addition, since the conductive yarn 100 and the wet guiding yarn 200 are both flexible materials, the fabric electrode device has relatively excellent characteristics such as softness, extensibility, comfort in contact with a human body, and the like, and is convenient to integrate in a wearable device.

In one embodiment, the second coil 201 may cover the first float wire 102 in the third direction and the first coil 101 may cover the second float wire 202 in the third direction.
