Abstract
The invention provides a stretchable elastic fabric lead and a fabric with a circuit, which comprises a fabric substrate and metal conductive yarns arranged in the fabric substrate, wherein the conductive yarns wrap an insulating coating; each metal conductive yarn is woven into or embedded in the elastic fabric substrate and at least a portion of the metal conductive yarn forms a continuous bend or wave. In this embodiment, because the metal conductive yarn is continuously bent along the transverse direction or the longitudinal direction, the bent portions can generate angle changes during stretching to enable the length of the continuous metal conductive yarn to be longer, and the continuous metal conductive yarn is restored to the original shape after external force is applied, so that the original non-stretchable metal conductive yarn can be stretched in the conductive yarn by changing the bending angle. The embodiment enables the metal conductive yarn which cannot be stretched originally to have good stretching capacity through the fabric conductive wire fabric. In addition, the antistatic or electromagnetic shielding layer is covered or wrapped to realize electrostatic and electromagnetic shielding.

A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. In the medical field, wearable devices have wide applications, such as electrodes or sensors integrated in clothes, shoes and hats worn by people in daily life, and can realize real-time detection of physical signs or motion states of people.
In the wearable device, in order to extract the signal detected by the electrode or the sensor, a lead is often required to connect the sensor and the detection terminal. For general aesthetics, these conductors are also typically present as part of the garment, e.g., for fabric garments, the conductors are typically embedded within the fabric threads. However, during the movement of people, the clothes can deform and stretch along with the movement of people, which causes the deformation and the stretching of the fabric threads, and the elasticity of the fabric threads is better than that of the conducting threads. It is therefore easy to see that the fabric threads do not match the properties of the fabric. In addition, when the fabric is worn, static electricity and electromagnetic interference can be generated, effective shielding is not performed, signals are subjected to strong interference, and the signals cannot be transmitted out correctly.

The insulating layer may be a non-conductive fabric or other insulating polymers, and the invention is not limited in particular. In particular, in this embodiment, the insulating layer is made of polyvinyl chloride (PVC), polyethylene, cross-linked polyethylene (XLPE), or other polymer.
In this embodiment, as shown in fig. 3, since the fabric wire is to be worn on a human body, static electricity is easily generated in the fabric itself because the outside of the metal conductive yarn 20 or the outside of the fabric substrate is coated with the static electricity shielding coating 30 for preventing the generation of static electricity.
Wherein the electrostatic shielding coating 30 is formed of a combination of conductive particles and a binder; or
The electrostatic shielding coating 30 is formed from a combination of conductive particles, ferromagnetic particles, and a binder.
For example, OD0826, which is suitable for electromagnetic wave shielding of various plastic substrates such as ABS, ABS + PC, and PC, can be used as the electrostatic shielding coating 30.
In this embodiment, if the cross section of the metal conductive yarn 20 is circular, the electrostatic shielding coating 30 is coated on the entire outer side of the metal conductive yarn 20, and if the cross section of the metal conductive yarn 20 is rectangular, the electrostatic shielding coating 30 is coated on the upper and lower surfaces of the metal conductive yarn 20, and then the metal conductive yarn is electrically connected through a conductive wire (as shown in fig. 2).

Preferably, when there are a plurality of the metal conductive yarns 20, the plurality of metal conductive yarns 20 are arranged in a width direction or a radial direction of the fabric substrate 10.
