Description

TECHNICAL FIELD

[0001] The utility model relates to an electrode structure for electromyostimulation and electromyography, in particular to a fabric structure for electromyostimulation and electromyography electrodes of textiles. BACKGROUND

[0002] In the field of sports rehabilitation, it is a very common therapy to use functional electrical stimulation (FES) to introduce electric current into the subcutaneous tissue to stimulate the nervous system to cause muscle contraction to promote limb function.

[0003] In addition, in some electronic interactive game devices, the players need to wear electromyography electrodes to sense human body movements, and then transmit and receive sensing signals between sensors and electronic devices.

[0004] Traditional electromyostimulation electrodes and electromyography electrodes are mostly disposable gel patches that cannot be reused after use, causing environmental pollution. In particular, traditional electromyostimulation electrodes and electromyography electrodes must be manufactured separately due to different voltages, which further increases the amount of disposal after use.

[0005] To solve the aforementioned problems, reusable fabric electrodes have been developed, such as Taiwan Patent Publication No. 202408618, which provides an electrode structure for electromyostimulation, including a conductive fabric layer, a water-retaining fabric layer, and an insulating protective layer. The conductive fabric layer has opposite first and second surfaces, and the water-retaining fabric layer is connected to the first surface of the conductive fabric layer. The electromyostimulation point of the electrode structure is only composed of the water-retaining fabric layer. The insulating protective layer is arranged on the first surface of the conductive fabric layer and surrounds the outer edge of the water-retaining fabric layer. However, the structure of this fabric electrode is relatively complex, and it can only provide the single function of "electromyostimulation electrode" and cannot provide "electromyography electrode". If the function of electromyography electrode is needed, it must be purchased separately. SUMMARY

By the fabric structure, myoelectricity stimulation electrode and myoelectricity sensing electrode are formed respectively in opposite two sides of fabric, and the user can select one side to contact the human body according to the demand, and the fabric structure is more simple than the existing fabric electrode, and the production cost is lower.

[0008] Preferably, in the myoelectricity sensing area, the second conductive yarn can be connected with the first conductive yarn and the peripheral yarn.

[0009] Preferably, the second conductive yarn can be sequentially connected with the first conductive yarn and the peripheral yarn, so that a plurality of first connection points are formed in the myoelectricity sensing area, and a plurality of second connection points are formed in the myoelectricity stimulation area, and the plurality of first connection points and the plurality of second connection points are staggered.
