Description

Technical Field

[0001] This utility model relates to the field of electrode technology, and in particular to a moisturizing electrode. Background Technology

[0002] Electrocardiography (ECG), as a fundamental and crucial physiological monitoring tool in the medical field, has long played an indispensable role in the prevention, diagnosis, and treatment of heart diseases. By analyzing the periodic changes in cardiac electrical activity, it provides doctors with direct evidence about the state of cardiac function and potential pathological problems. With advancements in technology and the increasing demand for health monitoring, ECG monitoring technology is gradually moving from traditional medical settings into daily life. Among these technologies, ECG clothing, as an innovative wearable device, cleverly integrates ECG monitoring technology with everyday attire, enabling continuous and convenient monitoring of heart health and significantly improving the probability and efficiency of early detection of heart diseases.

[0003] However, despite the immense potential of ECG vests in terms of convenience and practicality, they still face a key challenge in practical applications: the quality of contact between the electrodes and the skin. Traditional ECG vests generally employ dry electrode designs, such as fabric electrodes or conductive rubber electrodes. When these electrodes come into direct contact with the skin, the lack of sufficient wettability often leads to high contact impedance, resulting in increased contact noise. This noise not only reduces the clarity of the ECG signal but may also introduce interference signals that are difficult to completely eliminate through post-processing, severely interfering with the accuracy of the ECG and posing a significant obstacle to the accurate diagnosis of heart diseases. Utility Model Content

Detailed Implementation

[0030] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0031] In the description of this utility model, it should be noted that the orientation or positional relationship indicated in this description is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the parts or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Please refer to the following: Figure 1-4 This invention provides a moisturizing electrode 100, comprising an electrode layer 10 and a moisturizing inner core 20. One side of the electrode layer 10 is for contact with the skin, and the other side is for contact with the moisturizing inner core 20. The moisturizing inner core 20 includes a permeation layer 21 and a moisture-locking layer 22. The moisturizing electrode 100 provided by this invention can achieve the slow release of conductive media or ions, thereby improving the conductivity and stability of the electrode under dry conditions.

[0033] In one embodiment of this invention, a moisture-absorbing material is added inside the moisturizing core 20, which can absorb moisture from the environment. Specifically, the moisture-absorbing material includes one or more of calcium chloride, lithium chloride, magnesium oxide, activated carbon, and silica (silicon dioxide). It should be noted that the moisture-absorbing material is not shown in the figures.

[0034] In one embodiment of this invention, the moisturizing electrode 100 further includes a permeable layer for wrapping the moisturizing inner core 20. This permeable layer is a selective permeable layer, allowing water vapor to pass through while preventing the hygroscopic material inside the moisturizing inner core 20 from dissolving and seeping out. The permeable layer is a nanofiltration membrane or a reverse osmosis membrane. The permeable layer works in conjunction with the permeable layer 21 to ensure water vapor permeation, prevent the hygroscopic material from seeping out, and control the release rate of the conductive medium or ions, enabling the electrode to provide long-term moisturizing. It should be noted that the permeable layer is not shown in the figures.

[0035] In one embodiment of the present invention, the moisturizing electrode 100 further includes a fabric layer 30, and the moisturizing inner core 20 of the fabric layer 30 is in contact with the side opposite to the electrode layer 10.

[0036] Specifically, the electrode layer 10, the moisturizing inner core 20, and the fabric layer 30 are aligned in the center of the horizontal area and connected together by heat pressing or bonding. They are not easy to fall off during machine washing, are not easy to deform when pulled, and are not easy to expose loose threads. Therefore, they have higher reliability and higher integration and aesthetics. The electrode layer 10 is used for conduction and is typically made of conductive fabric, including but not limited to conductive silver fiber fabric, stainless steel fabric, conductive rubber, etc., to facilitate skin contact and avoid skin damage. The permeation layer 21 is used to control the release rate of the conductive medium or ions in the moisture-locking layer 22, ensuring that the electrode can maintain long-term moisturizing effect. Specifically, when the conductive medium or ions are selected as a solution or water, the permeation layer 21 is preferably a waterproof and breathable fabric, which facilitates the release of the solution into the electrode layer 10 to improve conductivity and reduce contact resistance. The moisture-locking layer 22 is used to lock in the conductive medium or ions, preventing the conductive medium and / or ions from being released too quickly, which would result in an excessively short moisturizing time for the entire moisturizing electrode 100. Specifically, the moisture-locking layer 22 includes but is not limited to flexible sheets made of absorbent gel, polymer liquid materials, sponges, cotton, etc. The fabric layer 30 is ordinary clothing fabric or other fabrics. Optionally, a heating structure can be integrated into the fabric layer 30, such as fabric with integrated heating wires or graphene heating circuits. More preferably, a temperature control chip can be integrated to control heating or cooling through an external circuit. In addition, the moisture-locking layer 22 can periodically replenish the conductive medium and / or ions. Specifically, when the conductive medium or ions are water, water can be automatically replenished through the machine washing process; when the conductive medium or ions are other solutions, they can be replenished by soaking.

[0037] In one embodiment of the present invention, the moisturizing inner core 20 further includes an isolation layer 23, a permeable layer 21, a moisture-locking layer 22, and the isolation layer 23 are sequentially disposed between the electrode layer 10 and the fabric layer 30 in the direction from the electrode layer 10 toward the fabric layer 30; the isolation layer 23 is used to prevent conductive media and / or ions from being released to the environmental side, that is, in the direction toward the fabric layer 30, and the isolation layer 23 can be made of waterproof fabric, TPU, waterproof leather, or other materials.

[0038] Please see Figure 3The moisturizing electrode 100 provided by this utility model can be widely used in fields such as batteries, supercapacitors, sensors, and bioelectronic devices, especially in application scenarios requiring long-term stable operation and where environmental humidity is uncontrollable. In this embodiment, the moisturizing electrode 100 is applied to an ECG garment 50, wherein the electrode layer 10 is in contact with the human skin, the fabric layer 30 is disposed on the ECG garment 50, and the electrode layer 10 is provided with a wire 40, which electrically connects the electrode layer 10 to the ECG garment 50. Multiple moisturizing electrodes 100 can be disposed on the ECG garment 50. In this embodiment, three moisturizing electrodes 100 are disposed on the ECG garment 50, two of which are disposed on the chest and one on the back. In addition, elastic bands or binding bands can be provided at the moisturizing electrodes 100 to improve the contact between the textile electrodes and the wearer's skin and reduce poor contact caused by the wearer's movements. Because the electrodes on conventional ECG vests 50 use hydrogel to contact the skin, they can cause skin damage and infection, resulting in poor comfort. Furthermore, their conductivity is poor in dry environments. In contrast, the moisturizing electrode 100 provided by this invention, through the setting of the moisturizing inner core 20, can optimize the release rate and distribution of conductive medium or ions, effectively regulate the moisture content of the electrode surface, avoid skin discomfort or electrode failure caused by excessive moisture, and ensure that the electrode can maintain an ideal moist state during long-term wear. This effectively resists interference from the external environment and provides users with a more accurate and comfortable ECG monitoring experience.

[0039] Please refer to it again. Figure 1 In one embodiment of this utility model, a monitoring sensor 60 for monitoring ambient humidity can be provided on the fabric layer 30. It can be used to monitor ambient humidity, activate the temperature control plate to heat or cool according to the humidity, and promote the release of conductive medium or ions in the lock layer by condensation or heating. The result of the dryness can be transmitted to the signal processing unit on the ECG garment 50, and switch filter parameters, algorithm parameters, etc. according to the dryness.

[0040] Please see Figure 8 When the monitoring sensor 60 detects a decrease in humidity, the contact impedance between the electrode and the skin increases, leading to increased contact noise. In this case, the filter should be narrowed to the frequency band corresponding to the heart rate, sacrificing some waveform characteristics of the electrocardiogram (ECG) to ensure the accuracy of heart rate calculation. When the monitoring sensor 60 detects a moderate rise above the threshold, the filter parameters are adjusted back to the normal bandwidth to ensure the integrity of the ECG. Here, α is a constant, ranging from 0 to 1, preferably 0.6. It should be noted that the filter can be a hardware filter or a software filter; in this embodiment, a hardware filter is used.

[0041] Please refer to it again. Figure 1 and Figure 2The moisturizing core 20 in this invention can be divided into a permeation layer 21, a moisture-locking layer 22, and an isolation layer 23, or the permeation layer 21, moisture-locking layer 22, and isolation layer 23 can be connected together as an independent module. This independent module is then detachably filled between the ECG layer 10 and the fabric layer 30. In the embodiment where it is an independent module, the ECG layer 10 and the fabric layer 30 are connected on both sides by ordinary fabric, with an opening on one side. The moisturizing core 20 is inserted into the opening and finally sealed with Velcro. The moisturizing core 20 of the independent module can be a disposable consumable, or it can be replenished with conductive media and / or ions after use through soaking, high-pressure injection, etc. Figure 1 A schematic diagram of the structure of the 20-layer moisturizing inner core; Figure 2 A schematic diagram of the structure of the moisturizing inner core 20 as an independent module.

[0042] Please refer to the following: Figure 4 and Figure 5 The electrode layer 10 includes a pressing gasket 11 and a first textile layer 12; the permeation layer 21 includes a second textile layer 211; the moisture-locking layer 22 includes a waterproof layer and a protective layer 222, an absorbent layer 223, and a water-locking layer 224 disposed within the waterproof layer; the waterproof layer includes a waterproof surface layer 221 and a waterproof bottom layer 225. The pressing gasket 11 and the first textile layer 12 together constitute the electrode layer 10; the second textile layer 211, the moisture-locking layer 22, and the insulating layer 23 constitute the moisturizing inner core 20; and the fabric layer 30 is a regular fabric.

[0043] The projected area of ​​the first textile layer 12 and the second textile layer 211 is smaller than the projected area of ​​the pressing washer 11, and the projected area of ​​the second textile layer 211 may or may not be equal to the projected area of ​​the first textile layer 12. One or more layers of the first textile layer 12 and the second textile layer 211 may be provided. The first textile layer 12 is composed of one or more of stainless steel fibers, silver-plated yarn, or silver fiber cloth, and can be rectangular or other shapes. The second textile layer 211 is composed of cotton material and can be rectangular or other shapes. The conductor 40 is disposed on the first textile layer 12 and located between the first textile layer 12 and the second textile layer 211. The pressing washer 11 includes an edge portion 111 and a hollow portion 112. The edge portion 111 is connected to the fabric layer 30, and the hollow portion 112 is the part of the pressing washer 11 excluding the edge portion 111. The pressing washer 11 can be rectangular or other shapes. The lower surface of the pressing washer 11 contains an adhesive film that melts under hot pressing conditions and becomes sticky. The fabric layer 30 is clothing fabric or other materials that can be bonded together with the melted adhesive film of the pressing washer 11. The moisture-locking layer 22 can be rectangular or other shapes. The waterproof layer is provided with through holes 24. The through holes 24 can be any shape other than circular, and the through holes 24 can be provided on the waterproof surface layer 221 or on the waterproof bottom layer 225. The through holes 24 can be one or more, or they can be an array of micropores. The through holes 24 can be large or small and can be adjusted according to actual needs. In this embodiment, two through holes 24 are provided on the waterproof surface layer 221. The wire 40 can be made of conductive material; the inside of the moisturizing electrode 100 can be increased to elevate the electrode.

[0044] Specifically, the conductor 40 extends from the first textile layer 12. The pressing gasket 11, the first textile layer 12, the second textile layer 211, the waterproof surface layer 221, the protective layer 222, the absorbent layer 223, the water-locking layer 224, and the waterproof bottom layer 225 are assembled together by hot pressing or bonding. After assembly, the area covered by the pressing gasket 11 is tightly attached to the fabric layer 30, and the hollow part 112 of the pressing gasket 11 is raised by the moisture-locking layer 22. The specific working principle is as follows: the first textile layer 12 is a soft silver-plated spun fabric, which is breathable and non-irritating, and has low impedance and high electrical signal transmission efficiency. The second textile layer 211 is a cotton fabric, which is soft and increases the comfort of placing the electrode. The cotton fabric better regulates the conductive medium and / or ions, making them more evenly distributed. In addition to initially filling the conductive medium and / or ions, the moisture-locking layer 22 can also absorb and store the surrounding dielectric (such as water, sweat, etc.) and then slowly release it, thereby achieving the effect of humidifying the surface of the textile electrode. The moisture-locking layer 22 also elevates the upper first textile layer 12, allowing the first textile layer 12 to make more full contact with the skin, thereby improving the contact efficiency between the electrode and the contact surface such as the skin.

[0045] Please refer to the following: Figure 6 and Figure 7 The waterproof top layer 221, protective layer 222, absorbent layer 223, water-locking layer 224, and waterproof bottom layer 225 are arranged sequentially from the second textile layer 211 toward the fabric layer 30. The forward projected area of ​​the protective layer 222, absorbent layer 223, and water-locking layer 224 is smaller than that of the waterproof top layer 221 and the waterproof bottom layer 225. The waterproof top layer 221, protective layer 222, absorbent layer 223, water-locking layer 224, and waterproof bottom layer 225 are combined together through processes such as hot pressing or bonding.

[0046] The waterproof surface layer 221 is composed of a TPU film and a fluorine-free hydrophobic woven fabric, or other materials. In this embodiment, through-holes 24 are provided on the waterproof surface layer 221, allowing liquid to enter and exit the moisture-locking layer 22 through the through-holes 24. The waterproof surface layer 221 can be rectangular or other shapes. The protective layer 222 is composed of non-woven fabric, cotton fabric, or other materials. The protective layer 222 can be rectangular or other shapes. The absorbent layer 223 is composed of absorbent materials, including but not limited to sponges, absorbent resins, absorbent gels, or other materials. The absorbent layer 223 can be rectangular or other shapes. The water-locking layer 224 is composed of water-locking materials, including but not limited to sponges, absorbent resins, absorbent gels, or other materials. The water-locking layer 224 can be rectangular or other shapes. The difference between the water-locking layer 224 and the absorbent layer 223 is that the liquid in the water-locking layer 224 diffuses faster and is more easily distributed evenly. The waterproof bottom layer 225 is composed of a TPU film and a fluorine-free hydrophobic woven fabric, or other materials. Both the waterproof top layer 221 and the waterproof bottom layer 225 are made of leather, rubber, or other waterproof materials. The waterproof top layer 221 and the waterproof bottom layer 225 can be rectangular or other shapes.

[0047] As described above, the moisturizing electrode provided by this invention, by setting a moisturizing inner core 20 between the electrode layer 10 and the fabric layer 30, can realize the functions of electrode water storage and humidification. Through holes 24 are provided on the surface of the moisture-locking layer 22 to allow the entry and exit of humidifying media (such as water). The moisture-locking layer 22 can be replenished with conductive media and / or ions through machine washing, soaking, high-pressure injection, etc. The assembled moisture-locking layer 22 elevates the upper first textile layer 12, allowing the first textile layer 12 to make more full contact with the skin, thereby improving the contact efficiency between the electrode and the contact surface such as the skin. The electrode layer 10 is made of flexible silver-plated fiber, which has low impedance and high electrical signal transmission efficiency, and will not cause harm to the skin. In summary, the moisturizing electrode provided by this invention, through dual optimization of material innovation and structural design, can achieve the slow release of conductive media or ions, thereby improving the conductivity and stability of the electrode under dry conditions.
