1. Structural composition of the TENS electrodes pad

The structure of the treatment electrode sheet may seem simple, but it is actually composed of multiple layers of material, ensuring good electrical conductivity, comfort and durability. In general, the physiotherapy electrode is composed of the following main parts:

1. Conductive layer: This is the core part of the electrode, usually made of a material with good electrical conductivity, such as carbon fiber or silver fiber, which can effectively transmit electrical stimulation signals to the skin surface, and through the skin to the muscle or nerve.

2. Sticky gel layer: In order to ensure that the electrode can firmly adhere to the skin and ensure the effective conduction of current, the surface of the electrode is usually covered with a layer of sticky gel. This layer not only provides a comfortable fit, but also reduces skin discomfort caused by electrical stimulation.

3. Backing layer: In order to protect the conductive layer and adhesive layer of the electrode sheet, the backing layer is usually made of flexible materials, such as PVC or other polymer materials. It not only improves the durability of the electrode, but also facilitates the operation and movement of the electrode.

4. Connection line/interface: The connection line or interface is the link between the electrode and the electrical stimulation device, usually using a standardized interface design to facilitate the universality of various electrical stimulation devices.

2. The working principle of the TENS electrodes

Physiotherapy electrode sheet mainly through the principle of electrical stimulation to achieve the physiotherapy effect. By connecting the electrical stimulation device, the electrode plate transmits the low-frequency or medium-frequency current output by the device to the surface tissue of the human body, and then acts on muscles, nerves and other parts.

1. Current conduction: When the device is energized, the electrode sheet conducts the current to the skin surface through the conductive layer. Depending on the physiotherapy needs, the current can stimulate superficial or deep tissues to relieve pain, relax muscles or improve blood circulation.

2. Nerve stimulation: Electrical stimulation interferes with the transmission of pain signals by acting on nerve fibers, thereby reducing pain. Clinically, physiotherapy electrodes are often used to relieve chronic pain, promote the healing of the injured site and accelerate postoperative rehabilitation.

3. Muscle stimulation: The stimulation of electric current can also cause muscle contraction, which is particularly important for people who are in bed for a long time or have little activity, and can effectively prevent muscle atrophy and maintain muscle activity.
