Abstract
Description
Technical Field
[0001] This invention relates to the field of wearable medical devices using textile materials, specifically to a 12-lead ECG monitoring garment based on biomimetic embroidered electrodes. Background Technology
[0002] Cardiovascular disease is a leading cause of death worldwide, characterized by its long-term, cumulative, and sporadic nature. Routine medical checkups are insufficient to meet the needs of continuous daily monitoring. Therefore, wearable real-time monitoring devices for human electrocardiogram (ECG) signals have become an important support for clinical diagnosis and home health management. As the core method for detecting cardiac electrical activity, electrocardiography (ECG) is a routine means of predicting and diagnosing cardiovascular diseases.
[0003] Traditional clinical dynamic electrocardiogram (ECG) monitoring typically employs a 12-lead Ag / AgCl gel electrode scheme, requiring the use of conductive gel. Multiple leads connect to the recorder, using four limb electrodes (RA, LA, LL, RL) and six chest wall electrodes (V1, V2, V3, V4, V5, V6) to acquire ECG signals. This monitoring method has several drawbacks: the conductive gel gradually dries after prolonged use, leading to increased skin-electrode interface impedance and decreased signal quality; the gel and adhesive can easily cause skin itching and allergic reactions, making it unsuitable for users requiring long-term continuous monitoring or those with sensitive skin; electrode placement requires professional operation, which is difficult for patients to perform accurately, and the process is cumbersome and time-consuming. Furthermore, uneven sweating distribution in the human body results in areas with high sweating (electrodes V5, V6, RA, LA), moderate sweating (electrodes V1, V2, V3, V4), and low sweating (electrodes RL, LL). Sweat affects electrode adhesion, disrupts the electrode-skin interface, and reduces the quality and stability of ECG signal acquisition.
[0004] To address the aforementioned issues, intelligent ECG monitoring garments integrating ECG monitoring functions have emerged, becoming a mainstream direction in technological development. Among existing technologies, Chinese patent CN214907064 U uses fabric electrodes connected to a detachable monitoring terminal via conductive strips, achieving electrode reuse and a detachable monitoring terminal; Chinese patent CN221813966U improves the wearing experience and garment fit through a front zipper and waist-cinching design, reducing the impact of electrode displacement on monitoring. However, existing smart ECG monitoring clothing technology has not yet broken through core technological bottlenecks and has many problems that urgently need to be solved: First, it is not specifically designed for the differences in the distribution of sweat zones on the human body. Under dynamic activity or sweating conditions, the impedance of the electrode-skin interface is prone to large fluctuations, resulting in high ECG signal noise, obvious baseline drift, and insufficient stability and accuracy of monitoring. It cannot solve the dual interference of sweat zone differences and dynamic activity on signal acquisition. Second, some solutions still use disposable electrode pads, which not only have poor reusability but also easily cause skin allergies, failing to meet the skin-friendly requirements of long-term continuous monitoring. Third, the overall technical solution is difficult to balance the high fidelity of ECG signals under long-term and dynamic monitoring with the convenience and comfort of wearing it, which is far from meeting the actual application needs of daily self-monitoring of ECG.
[0005] Therefore, developing a 12-lead ECG monitoring device that can adapt to the differences in the distribution of sweat zones in the human body, balance the stability of dynamic monitoring signals and wearing comfort, and enable autonomous and convenient operation has become a key direction for solving the pain points of existing technologies and meeting the daily monitoring needs of cardiovascular diseases. Summary of the Invention
[0006] To address the problems in existing technologies, this invention provides a 12-lead ECG monitoring garment based on biomimetic embroidered electrodes that targets the distribution of sweating areas on the human body. This ECG monitoring garment combines biomimetic embroidered electrodes with excellent dry / wet adhesion and dynamic sensing stability with an optimized garment structure to achieve continuous and stable acquisition of 12-lead ECG signals under various exercise conditions, while taking into account both ease of wear, comfort, and clinical testing accuracy.
[0007] To achieve the above technical objectives, the present invention provides a 12-lead electrocardiogram monitoring garment based on bionic embroidered electrodes, the electrocardiogram monitoring garment comprising a garment body (1), bionic embroidered electrodes (2), a signal transmission component (3), and an electrocardiogram recorder (4).
[0008] The garment body is made of elastic knitted fabric and is a round neck sleeveless vest style. The right waist of the garment body has a Velcro adjustment structure (5).
[0009] The bionic embroidery electrode (2) is made of conductive yarn (21) and sewn onto the inner side of the garment body (1) through bionic embroidery process, and is in direct contact with the human body. It is designed according to the differentiating areas of low sweat, medium sweat and high sweat of the human body, and its arrangement position is adapted to the position in the standard 12-lead system of the human body.
[0010] The signal transmission component (3) includes a metal electrode buckle (31) and a detachable lead wire (32). The metal electrode buckle (31) is connected to the bionic embroidery electrode (2) one by one. One end of the detachable lead wire (32) is connected to the metal electrode buckle (31), and the other end is connected to the electrocardiogram recorder (4). The connection is detachable.
[0011] In some technical solutions of the present invention, the size of the garment body is 160 / 84A to 165 / 88A.
[0012] In some technical solutions of the present invention, the elastic knitted fabric is a knitted fabric blended with polyester, viscose, and spandex.
[0013] In some preferred embodiments of the present invention, the blending ratio is 65%–70% polyester, 25%–30% viscose, and 5%–10% spandex.
[0014] In some preferred embodiments of the present invention, the elastic knitted fabric has a weight of 260-280 g / m² and a thickness of 1.0-1.1 mm.
[0015] In some technical solutions of the present invention, the Velcro adjustment structure (5) includes a hook side sewn to the front piece of the garment and a loop side sewn to the back piece of the garment. The fitting position can be adjusted according to the wearer's body shape to ensure that the garment body fits tightly to the body of the person being tested.
[0016] In some technical solutions of the present invention, the bionic embroidery electrode (2) is embroidered in a circular shape, and the inside of the circle is uniformly sewn with bionic stitches to form a columnar structure (20) with a hexagonal cross-section. Further, the columnar structure (20) with a hexagonal cross-section is formed by embroidering conductive yarn (21) through bionic stitches covering a sponge pad (22). Specifically, the sponge pad (22) is directly superimposed on the inner surface of the garment body (1) in a certain distribution, and the conductive yarn (21) fixes the sponge pad (22) to the inner surface of the garment body (1) through bionic stitches and forms a continuous hexagonal columnar structure (20) to constitute a complete bionic embroidery electrode (2).
[0017] In some preferred embodiments of the present invention, the circular dimension is 20-30 mm.
[0018] In some preferred embodiments of the present invention, the stitch parameters of the biomimetic stitch are: line spacing 0.2-0.3 mm, and number of stitches 500-650.
[0019] In some preferred embodiments of the present invention, the unit size of the hexagonal columnar structure (20) is 4×4 to 8×8 mm², the height of the hexagonal columnar structure (20) is 1.0 to 3.0 mm, and the width of the groove (23) between the hexagonal columnar structures (20) is 0.1 to 0.2 mm.
[0020] In some preferred embodiments of the present invention, the bionic embroidery electrode adjusts the number and density of the sponge pad (22) and the cross-sectional shape of the hexagonal columnar structure (20) according to different sweat areas to adapt to the characteristics of low-sweat areas, medium-sweat areas and high-sweat areas, thereby improving the stability of dynamic monitoring signals.
[0021] In some preferred embodiments of the present invention, the biomimetic embroidery electrode suitable for areas with low sweating is based on a biomimetic design of gecko bristles. The sponge pad consists of two layers of PU sponge with different densities stacked together. The biomimetic columnar structure is hard at the bottom and soft at the top, exhibiting a mushroom-like shape that is larger at the top and smaller at the bottom. When compressed against the human body, the soft upper part deforms to increase the contact area, while the lower part remains stable and does not deform, thereby increasing the stability of contact with the skin. Furthermore, the density of the upper PU sponge is 20-25 kg / m³. 3 The density of the lower PU sponge is 35-40 kg / m³. 3 The thickness ratio of the upper and lower PU sponge layers is 2:1 to 3:1. The biomimetic embroidery electrodes suitable for low-perspiration areas are used at the RL and LL positions.
[0022] In some preferred embodiments of the present invention, the biomimetic embroidery electrode suitable for sweaty areas is based on a biomimetic design of a tree frog's foot structure, the sponge pad is a single layer of PU sponge, and the biomimetic columnar structure has a uniform hardness throughout. When in contact with human skin in sweaty areas, the groove structure between the biomimetic columns ensures stability, accommodates sufficient sweat, increases the adhesion between the electrode and the human body, and facilitates the excretion of excess sweat. Furthermore, the density of the PU sponge is 35–40 kg / m³. 3 The biomimetic embroidery electrodes applicable to areas with high sweating are used at positions V5, V6, RA, and LA.
[0023] In some preferred embodiments of the present invention, the biomimetic embroidery electrode suitable for the sweat zone is a biomimetic design combining the structure of gecko bristles and the foot structure of a tree frog. Specifically, the sponge pad is composed of two layers of PU sponge with different densities. Further, the density of the upper PU sponge is 20-25 kg / m³. 3 The density of the lower PU sponge is 35-40 kg / m³. 3The thickness ratio of the upper and lower PU sponge layers is 1:1. The biomimetic embroidery electrodes suitable for the sweat zone are used at positions V1, V2, V3, and V4.
[0024] In some technical solutions of this invention, the conductive yarn used in the biomimetic embroidery electrode is a nylon / silver composite conductive yarn. Further, the conductive yarn has a silver content of 15%–20%, a linear density of 25–30 tex, and a resistivity of 4 × 10⁻⁶. -4 ~5×10 -4 Ω·cm, with a diameter of 0.1 to 0.3 mm.
[0025] In some technical solutions of the present invention, the metal electrode buckle in the signal transmission component is fixed to the outside of the corresponding biomimetic embroidery electrode by sewing with conductive yarn.
[0026] In some technical solutions of the present invention, the lead wires in the signal transmission assembly are integrated with the electrocardiogram recorder into a detachable electronic module. Furthermore, the garment body is provided with a storage pocket for storing and securing the electrocardiogram recorder.
[0027] In some technical solutions of the present invention, the electrocardiogram recorder is equipped with an electrocardiogram signal analysis system for real-time recording and analysis of the collected 12-lead electrocardiogram data.
[0028] Compared with the prior art, the present invention has the following beneficial effects:
[0029] 1. High signal acquisition quality and good dynamic stability. The biomimetic embroidery electrode used in this invention has a hexagonal columnar structure on its surface that can generate capillary force in both dry and wet environments, enhancing the adhesion between the electrode and the skin and effectively reducing the impact of dynamic displacement on the skin-electrode interface impedance. Real-person wearing experiments show that, when wearing the ECG monitoring garment of this invention in sitting, walking, and jogging states, the Pearson correlation coefficient between the ECG waveform measured by the garment and the gel electrode is ≥0.80; the QRS complex recognition rate is ≥94%; and there are no significant differences in core indicators such as total heart rate and heart rate (P≥0.05), proving that it has signal acquisition accuracy comparable to medical-grade gel electrodes.
[0030] 2. Significantly improved ease of wear. The ECG monitoring garment of this invention adopts an integrated garment design. Users only need to wear it and connect the lead wires to begin monitoring, eliminating the need to attach individual electrode pads. Experimental data shows that the average wearing time of the ECG monitoring garment of this invention is ≤58 seconds, which is more convenient than gel electrodes, making it particularly suitable for home monitoring scenarios requiring frequent wear or patient self-operation.
[0031] 3. Excellent wearing comfort and high skin-friendliness. The garment itself is made of a soft, highly elastic blended fabric, combined with a round neck, sleeveless design, and adjustable waist Velcro, ensuring a comfortable wearing experience. The use of gel-free fabric electrodes completely avoids the risk of skin irritation from chemical adhesives, further enhancing comfort. Post-experimental skin condition assessment showed that the skin-friendliness score of this ECG monitoring garment is ≥4.0 out of 5, indicating superior comfort and suitability for dynamic, long-term continuous monitoring.

The sponge pad 22 is directly superimposed on the inner surface of the garment during embroidery processing, and then inserted into the bionic embroidery electrode after processing, thereby forming a bionic structure. Figures 4-6 As shown, the biomimetic embroidery electrode structure is a biomimetic design based on gecko bristles and tree frog foot structure, which are respectively suitable for the low-sweat area, high-sweat area and medium-sweat area of the human body.
[0044] Specifically, the garment body is size 160 / 84A; the Velcro adjustment structure on the right waist includes a hook side sewn to the front piece of the garment and a fleece side sewn to the back piece of the garment.
[0045] Specifically, the elastic knitted fabric is a polyester / viscose / spandex blended knitted fabric with a blend ratio of 66% polyester, 28% viscose, and 6% spandex; the fabric has a weight of 270g / m² and a thickness of 1.05mm.
[0046] Specifically, the biomimetic embroidery electrode 2 is circular in shape with a diameter of 26mm; the stitch parameters are: line spacing 0.3mm, unit size 7×7mm², and 535 stitches. The hexagonal columnar structure 20 has a height of 1.5mm, and the groove 23 between the columnar structures has a width of 0.15mm. For embroidery of the electrode in the low-sweat area, two layers of PU sponge 22 are layered as a pad, with the top sponge having a density of 25kg / m³. 3 The bottom sponge density is 40 kg / m³. 3 The height ratio is 2:1.

The top sponge density is 25kg / m³. 3 The bottom sponge density is 40 kg / m³. 3 The height ratio of the two is 1:1.
[0047] Specifically, the conductive yarn 21 used in the biomimetic embroidery electrode 2 is a nylon / silver conductive yarn, with a silver content of 18%, a linear density of 27.8 tex, and a resistivity of 4.21 × 10⁻⁶. -4 Ω·cm, with a diameter of 0.2mm.
[0048] Specifically, the metal electrode buckle 31 is sewn and fixed to the outside of the corresponding bionic embroidered electrode by nylon / silver conductive yarn; the lead wire 32 and the electrocardiogram recorder 4 are integrated into a detachable electronic module; the garment body 1 is provided with a storage pocket for accommodating the electrocardiogram recorder.
[0049] Specifically, the ECG recorder is equipped with the AI-ECG Platform ECG signal analysis system, which is used to record and analyze the collected 12-lead ECG data in real time.
[0050] Based on the standard 12-lead system, 10 electrode positions were determined on the inner side of the garment body 1: limb electrodes were located below the clavicles and ribs on both sides, and chest wall electrodes V1~V6 were located point by point along the right edge of the sternum to the left mid-axillary line. Then, the electrode patterns were designed independently using PE-DESIGN NEXT embroidery pattern making software, and then input into the NV180 computer embroidery sewing machine for electrode preparation, directly embroidering conductive yarn onto the garment body 1 to form biomimetic embroidered electrodes 2.
[0051] On the outside of each biomimetic embroidered electrode 2, a copper-plated nickel metal electrode buckle 31 is sewn and fixed with conductive yarn. One end of the lead wire 32 is detachably connected to the electrode buckle 31, and the other end is converged and connected to the electrocardiogram recorder 4 stored in the chest pocket of the garment. The electrocardiogram recorder 4 is a portable electrocardiogram monitoring device with electrocardiogram signal acquisition, storage and wireless transmission functions, which can perform real-time analysis and diagnosis of the electrocardiogram data collected from 12 leads.
[0052] The electrocardiogram monitoring garment of the present invention was prepared according to the above method, and its performance was evaluated through real-person trial wearing experiments.
[0053] The real-person try-on experiment of this invention was conducted according to the following methods and evaluation indicators:
[0054] 1. Subjects wore the ECG monitoring garment of this invention and attached gel electrodes (control group) in three states: sitting, walking (3.2km / h), and jogging (6.4km / h). 12-lead ECG signals were collected and compared. SPSS software was used to process and statistically analyze the data.
[0055] 2. Functional stability was evaluated using waveform correlation coefficient and characteristic wave recognition rate. Correlation analysis was performed on the ECG signals measured by the ECG monitoring garment and gel electrodes, and the QRS complex recognition rate was calculated. Functional accuracy was evaluated using indicators such as total heart rate, heart rate, pulse amplitude, and baseline drift amplitude. Total heart rate and heart rate were automatically identified by the AI-ECG Platform software; pulse amplitude was obtained by calculating the QRS complex height; and baseline drift amplitude was obtained by calculating the vertical distance of the signal from the isoelectric line.
[0056] 3. Wearability: Record the time taken from taking out the product to being ready to wear.
[0057] 4. Skin-friendliness was assessed using the Draize rating system (5.0 points) to evaluate the degree of erythema on human skin after the experiment.

[0059] The 12-lead ECG monitoring garment based on biomimetic embroidered electrodes obtained in this embodiment of the invention provides stable and accurate signals during dynamic monitoring, is easy to wear, has high skin-friendliness, and combines functionality and comfort. Post-experiment skin condition assessment shows that the ECG monitoring garment of this invention has a skin-friendliness score ≥4.0 out of 5.0, indicating better comfort and suitability for dynamic long-term continuous monitoring.
