Description

Technical Field

[0001] This utility model relates to the field of physiological monitoring technology, and in particular to a device for measuring biological data. Background Technology

[0002] Chest-strap heart rate sensors are common sports equipment that allow users to measure heart rate, electrocardiogram (ECG), and other data by wearing them. They can provide physiological data for reference during training, preventing overexertion. At the same time, chest-strap heart rate sensors are also increasingly accepted as health monitoring devices.

[0003] A search revealed that patent application CN221807974U discloses a heart rate measurement device. The device features a first conductive fiber cloth on the side of the heart rate monitor facing the body, with one end of the cloth in contact with the skin proximal to the heart and the other end in contact with the skin distal to the heart. Electrodes are insulated from the first conductive fiber cloth, and a connector passes through and is insulated from it, thus forming a first closed electrical circuit with the human skin. The heartbeat generates a microcurrent in this closed circuit. Therefore, at least in one dimension, the first conductive fiber cloth can prevent or reduce interference from external electric and magnetic fields on the electrodes, thereby reducing the probability of errors in heart rate measurement data.

[0004] However, when wearers engage in activities such as running or cycling while wearing two or more layers of clothing containing polyester fibers in winter, a large amount of static electricity is generated and released due to the strenuous exercise and dry weather. In this case, the above-mentioned settings cannot guarantee the normal operation of the machine head.

[0005] In view of the shortcomings of the existing technology, this utility model proposes a device for measuring biological data. Utility Model Content

Detailed Implementation

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0040] For ease of description, in this invention, the side closer to the user's skin when the user wears or wears the biometric data detection device is considered the inside, and the side further away is considered the outside.

[0041] Example 1

[0042] Reference Figure 1-2 A device for measuring biological data includes a wearable device 1; the wearable device 1 is provided with a detection module 500 for processing electrical signals to obtain biological data.

[0043] An electrode sheet layer disposed on the wearable device 1, the electrode sheet layer including a first electrode 31 and a second electrode 32;

[0044] The first electrode 31 is at least partially in contact with the wearer's skin; the first electrode 31 is used to measure bioelectrical signals from the wearer's skin.

[0045] The second electrode 32 is at least partially in contact with the wearer's skin; the second electrode 32 is used to measure bioelectrical signals from the wearer's skin; the first electrode 31 and the second electrode 32 are not in contact; the first electrode 31 is located proximal to the second electrode 32.

[0046] Also includes:

[0047] Protective device installed on wearable device 1;

[0048] The protection device is electrically isolated from the electrode sheet;

[0049] The protective device is composed of two conductive fiber cloths, which are a first conductor 51 and a second conductor 52, respectively.

[0050] The first conductor 51 is disposed on the outside of the first electrode 31, and the first conductor 51 at least partially blocks the first electrode 31 and couples with the proximal end of the wearer. The second conductor 52 is disposed on the outside of the second electrode 32, and the second conductor 52 at least partially blocks the second electrode 32 and couples with the distal end of the wearer.

[0051] The first conductor 51 does not block the second electrode 32, and the second conductor 52 does not block the first electrode 31;

[0052] The shortest physical distance between the first conductor 51 and the second conductor 52 is no more than 15 mm, and the two form a capacitor structure through electric field coupling.

[0053] In this embodiment 1, the protective device is located on the outside of the electrode sheet layer.

[0054] In this embodiment 1, the protective device includes two conductive fiber cloths, which are a first conductor 51 and a second conductor 52, respectively. The first conductor 51 is coupled to the proximal end and at least partially blocks the first electrode 31 but does not block the second electrode 32. The second conductor 52 is coupled to the distal end and at least partially blocks the second electrode 32 but does not block the first electrode 31.

[0055] The first conductor 51 and the second conductor 52 are close to each other but not connected. The first conductor 51 and the second conductor 52 are close to each other on one side to form a capacitor structure. The shortest physical distance between the first conductor 51 and the second conductor 52 is no more than 15mm.

[0056] The first electrode 31 and the second electrode 32 are electrically isolated from the first conductor 51 and the second conductor 52 by the first insulating cloth 200.

[0057] In this embodiment 1, the wearable device 1 is an elastic fabric strip. A protective device is attached to the inside of the elastic fabric strip using TPU hot melt adhesive. The protective device consists of two unconnected conductive fiber fabrics, which are respectively a first conductor 51 and a second conductor 52. A first insulating fabric 200 is then attached to the first conductor 51 and the second conductor 52. The first insulating fabric 200 does not completely cover the first conductor 51 and the second conductor 52, leaving one end of the first conductor 51 away from the second conductor 52 exposed, and the other end of the second conductor 52 away from the first conductor 51 exposed. Two conductive rubber electrodes are then attached to the inside of the first insulating fabric 200; these two conductive rubber electrodes are the first electrode 31 and the second electrode 32.

[0058] The first conductor 51 blocks the first electrode 31 but does not block the second electrode 32. The second conductor 52 blocks the second electrode 32 but does not block the first electrode 31. In this embodiment 1, the projection of the first electrode 31 falls within the area projected by the first conductor 51. The projection of the second electrode 32 falls within the area projected by the second conductor 52.

[0059] The first insulating cloth 200 insulates the first electrode 31 from the first conductor 51, and also insulates the second electrode 32 from the second conductor 52. The first insulating cloth 200 exposes the first conductor 51 and the second conductor 52, allowing both the first conductor 51 and the second conductor 52 to come into contact with the skin when the device is worn.

[0060] Furthermore, two connectors 4 are provided between the detection module 500 and the electrode sheet, which are coupled to the first electrode 31 and the second electrode 32 respectively. In this embodiment, they are electrically connected. The connectors 4 are conductive and are used to transmit the electrical signals on the electrode sheet to the detection module 500.

[0061] like Figure 6The connector 4 is composed of a metal male buckle 4a, a metal female buckle 4b, and a metal base 4c. The metal male buckle 4a is disposed on the detection module 500 and is fastened to the metal female buckle 4b. The metal female buckle 4b is disposed on the outside of the wearable device 1. The electrode sheet is disposed on the inside of the wearable device 1. The metal base 4c is electrically connected to the first electrode 31 and the second electrode 32 respectively. The metal base 4c passes through the wearable device 1 and is electrically connected to the metal male buckle 4a and the metal female buckle 4b. The metal base 4c is electrically isolated from the conductive fiber cloth.

[0062] Specifically, in embodiment 1, through holes are provided on the sides of the first conductor 51 and the second conductor 52 that are close to each other. The metal base 4c passes through the through holes, and insulating adhesive is applied inside the through holes to achieve electrical isolation between the metal base 4c and the first conductor 51 and the second conductor 52.

[0063] A second insulating cloth 201 is attached to the inside of the first electrode 31 and the second electrode 32. The second insulating cloth 201 covers part of the first electrode 31 and the second electrode 32 to prevent the two electrodes from conducting signals due to sweat because they are too close together.

[0064] In this embodiment 1, the first conductor 51 and the second conductor 52 are close to each other, with a distance of 5mm between them. Since the first conductor 51 is partially in contact with the proximal end and the second conductor 52 is partially in contact with the distal end, the potential at the proximal end and the distal end is different due to heart activity. Therefore, the first conductor 51 and the second conductor 52 can form a capacitor structure on the side close to each other, and the distance between the plates of the capacitor structure is 5mm.

[0065] A second insulating cloth 201 is attached to the inside of the first electrode 31 and the second electrode 32. The second insulating cloth 201 covers part of the first electrode 31 and the second electrode 32 to prevent the two electrodes from conducting signals due to sweat because they are too close together.

[0066] The metal base 4c is connected to the first electrode 31 and the second electrode 32 respectively, and passes through the wearable device 1 to connect to the metal female buckle 4b located on the outside of the wearable device 1. The detection module 500 is provided with a metal female buckle 4a connected to the metal female buckle 4b.

[0067] Example 2

[0068] Reference Figure 3 The difference between this embodiment 2 and embodiment 1 is that, based on embodiment 1, a third electrode 33 and a fourth electrode 34 are also provided; the first conductor 51 is electrically connected to the third electrode 33 through the wire 6, and the first conductor 51 obtains the proximal end potential through the third electrode 33; the second conductor 52 is electrically connected to the fourth electrode 34 through the wire 6, and the second conductor 52 obtains the distal end potential through the fourth electrode 34.

[0069] The first electrode 31, the second electrode 32, the third electrode 33, and the fourth electrode 34 are electrically isolated from the first conductor 51 and the second conductor 52 by a first insulating cloth 200.

[0070] In embodiment 2, the first conductor 51 is electrically connected to the third electrode 33 through the wire 6, and the first conductor 51 is in contact with the proximal end through the third electrode 33. The second conductor 52 is electrically connected to the fourth electrode 34 through the wire 6, and the second conductor 52 is in contact with the distal end through the fourth electrode 34. Therefore, a capacitor structure is formed between the first conductor 51 and the second conductor 52.

[0071] Example 3

[0072] Reference Figure 4 The difference between Embodiment 3 and Embodiment 2 is that the first conductor 51 and the second conductor 52 are attached to the outside of the wearable device 1, and the wire 6 passes through the wearable device 1, connecting the first conductor 51 to the third electrode 33. The wire 6 passes through the wearable device 1, connecting the second conductor 52 to the fourth electrode 34. The outside of the first conductor 51 and the second conductor 52 can be coated with insulating adhesive. The remaining settings are the same as in Embodiment 2.

[0073] Example 4

[0074] Unlike Embodiment 1, the first insulating cloth 200 extends to both sides to completely cover the first conductor 51 and the second conductor 52. The first conductor 51 is capacitively coupled to the wearer's proximal end via the first electrode 31. The second conductor 52 is capacitively coupled to the wearer's distal end via the second electrode 32. The first electrode 31 and the second electrode 32 serve as the components for coupling the first conductor 51 and the second conductor 52 to the wearer's skin, respectively. The remaining configuration is the same as in Embodiment 1.

[0075] Example 5

[0076] Reference Figure 5 Unlike Embodiment 1, the protective device includes two conductive fiber cloths, which are a first conductor 51 and a second conductor 52, respectively. There is a projected overlap area between the first conductor 51 and the second conductor 52. Within this projected overlap area, the first conductor 51 and the second conductor 52 form a capacitor structure through electric field coupling. The remaining configuration is the same as in Embodiment 1.

[0077] In embodiment 5, the first conductor 51 and the second conductor 52 extend toward each other, such that a portion of the first conductor 51 is located inside or outside a portion of the second conductor 52; the first conductor 51 and the second conductor 52 are electrically isolated.

[0078] The first conductor 51 has a portion inside the second conductor. In embodiment 5, an insulating adhesive 202 with a thickness of 1 mm is applied between the first conductor 51 and the second conductor 52. The first conductor 51 and the second conductor 52 form a capacitor structure in this overlapping area, where the equivalent spacing is 1 mm.

[0079] like Figure 5 As shown, the first conductor 51 does not obstruct the second electrode 32, and the second conductor 52 does not obstruct the first electrode 31. When the device is worn, the first electrode 31 is in contact with the wearer's proximal skin, and the first conductor 51 is coupled to the wearer's proximal skin, where its potential is relatively close to that of the first electrode 31. The second electrode 32 is in contact with the wearer's distal skin, and the second conductor 52 is coupled to the wearer's distal skin, where its potential is relatively close to that of the second electrode 32. Therefore, when the first conductor 51 obstructs the first electrode 31, its influence on the electrical signal on the first electrode 31 is relatively small. However, when the first conductor 51 obstructs the second electrode 32, even if the first conductor 51 is very close to the first electrode 31, it will have a significant influence on the electrical signal on the second electrode 32. Similarly, when the second conductor 52 blocks the second electrode 32, the influence of the second conductor 52 on the second electrode 32 is relatively small. However, when the second conductor 52 blocks the first electrode 31, the second conductor 52 will have a greater impact on the electrical signal on the first electrode 31. Furthermore, in many embodiments, the protective device is attached tightly to the outside of the electrode sheet; for example, the thickness of the first insulating cloth 200 between the protective device and the electrode sheet is 0.01mm-2mm. If external interference, such as static electricity, exists near the protective device, when the first conductor 51 blocks the second electrode 32, the capacitive coupling between the two makes the impact of the external interference on the second electrode 32 relatively larger than when the first conductor 51 does not block the second electrode 32. Similarly, when the second conductor 52 blocks the first electrode 31, the impact of external interference on the first electrode 31 is also relatively larger than when the second conductor 52 does not block the first electrode 31. The initial design intent of this utility model is to protect the electrical signals of the first electrode 31 and the second electrode 32 through the protective device; obviously, minimizing the impact on the electrical signal on the electrode sheet is a priority. In this embodiment 5, the first conductor 51 completely blocks the first electrode 31, and the second conductor 52 completely blocks the second electrode 32.

[0080] Example 6

[0081] Based on Embodiment 1, the first insulating cloth 200 is extended to both sides of the elastic strip, so that the first insulating cloth completely covers the first conductor 51 and the second conductor 52 and prevents them from contacting the skin. When the wearer uses the device, the first electrode 31 and the second electrode 32 contact the proximal and distal ends of the wearer's skin, respectively.

[0082] The first conductor 51 is adjacent to the first electrode 31, and the first conductor 51 is capacitively coupled to the proximal end of the wearer through the first electrode 31. The second conductor 52 is adjacent to the second electrode 32, and the second conductor 52 is capacitively coupled to the distal end of the wearer through the second electrode 32. The first electrode 31 and the second electrode 32 serve as coupling components.

[0083] In embodiments 1-6 of this application, the metal base 4c needs to pass through the first electrode 31 and the second electrode 32 respectively, and be electrically connected to the first electrode 31 and the second electrode 32 respectively. It also needs to pass through the wearable device 1 and be installed and cooperated with the metal female buckle 4a and the metal female buckle 4b. At the same time, the metal base 4c is electrically connected to the metal female buckle 4a and the metal female buckle 4b.

[0084] In embodiments 1-6 of this application, a second insulating cloth 201 is attached to the inner side of the first electrode 31 and the second electrode 32. The second insulating cloth 201 covers part of the first electrode 31 and the second electrode 32 to prevent the two electrodes from conducting signals due to sweat because they are too close together.

[0085] In this application, the wearable device 1 is used to support the remaining components of the biological data detection device. Therefore, the wearable device 1 can be clothing, such as a tight-fitting garment like a bodysuit or sports bra, or it can be webbing, straps, or other devices that help it be worn on the body. In some embodiments, such as the scheme with patent publication number CN218391077U, the wearable device 1 consists of two unconnected woven fabric strips connected to the left and right ends of the detection module 500 respectively, thereby achieving wearability. In embodiments 1-6 above, the wearable device 1 uses an elastic fabric strip as an example.

[0086] In embodiments 1-6 of this application, the first electrode 31 and the second electrode 32 are electrically isolated from the first conductor 51 and the second conductor 52 by the first insulating cloth 200. In other embodiments, the first conductor 51 and the second conductor 52 can also be electrically isolated from the first electrode 31 and the second electrode 32 by other insulating materials such as insulating glue.

[0087] In embodiments 1-6 above, the first conductor 51 completely blocks the first electrode 31, and the second conductor 52 completely blocks the second electrode 32. In other embodiments, the first conductor 51 partially blocks the first electrode 31, and the second conductor 52 partially blocks the second electrode 32, depending on the actual situation.

[0088] In this application, the wearable device 1 is used to support the remaining components of the biometric data detection device. Therefore, the wearable device 1 can be clothing, such as a tight-fitting garment like a bodysuit or sports bra, or it can be webbing, straps, or other devices that help it be worn on the body. In some embodiments, such as the scheme with patent publication number CN218391077U, the wearable device 1 consists of two unconnected woven fabric straps connected to the left and right ends of the detection module 500, thereby achieving wearability. In the above embodiment, the wearable device 1 is an example of an elastic fabric strap. The elastic strap has Velcro clasps at both ends to allow it to wrap around the human chest.

[0089] The first electrode 31 and the second electrode 32 are at least partially in contact with the wearer's skin, thereby enabling the measurement of biological signals from the skin. The first electrode 31 and the second electrode 32 are adhered to one side of the wearable device 1 by adhesive, or they can be embedded or sewn onto the wearable device 1. When the first electrode 31 and the second electrode 32 are located on the outside of the wearable device 1, holes can be provided in the wearable device 1 to allow the first electrode 31 and the second electrode 32 to contact the skin. In some cases, the first electrode 31 and the second electrode 32 can be multilayered, with insulation between different layers, and electrical signals are transmitted using coupling methods such as capacitive coupling. Commonly, the first electrode 31 and the second electrode 32 are single-layered, and the materials used include, but are not limited to, conductive rubber, conductive fiber cloth, conductive adhesive containing AgCl, cloth woven from metal wires, and conductive film.

[0090] like Figure 1 The present invention is worn on a living organism. At this time, the first electrode 31 and the second electrode 32 acquire electrical signals from the organism through contact with the skin and transmit these signals to the detection module 500. Due to the heartbeat, a potential difference is generated between the proximal and distal ends. The electrical signals from the proximal and distal ends are transmitted to the detection module 500 through the first electrode 31 and the second electrode 32, respectively. The detection module 500 can identify the characteristics of the electrical signals using algorithms, formulas, etc., to derive data.

[0091] The detection module 500 is used to process electrical signals on the electrode sheets, including a circuit board or device configured to calculate biological data such as heart rate measurement, electrocardiogram (ECG), electroencephalogram, current analysis, and bioimpedance. The detection module 500 can transmit the acquired data to the wearer's mobile phone, watch, computer, or other electronic products for display via wireless transmission methods including but not limited to Bluetooth and ANT+, or via wired methods such as cables.

[0092] Common detection modules 500 include the POLAR H10 heart rate sensor, iGPSPORT HR50 heart rate sensor, and Mygen H603 heart rate sensor. Taking the POLAR H10 heart rate sensor as an example, after the wearer wears the biometric data detection device, the detection module 500 also has a Bluetooth module, which can transmit the data measured by the detection module 500 to the wearer's watch 800 via Bluetooth for display. The watch 800 can be an Apple Watch, a Garmin sports watch, or other existing products on the market.

[0093] In some designs, the first electrode 31 and the second electrode 32 are directly connected to the detection module 500, and connector 4 is not included in the all-in-one design, such as the Garmin HRM PRO PLUS heart rate chest strap. Connector 4 is not mandatory.

[0094] When connector 4 is provided, there are two connectors 4, which are coupled to the first electrode 31 and the second electrode 32 respectively. The coupling should be broadly defined, including physical connection by conductors. Connector 4 is used to transmit electrical signals from the electrode sheet to the detection module 500, including but not limited to wires, conductive coatings, metal snap fasteners, conductive iron pillars, components on the PCB circuit board, and coupling devices.

[0095] The protective device consists of two conductive fiber cloths. In some embodiments, the protective device is made of other conductive materials. Obviously, the protective device can be broadly considered to consist of two conductive materials. The materials selected for the conductive materials include, but are not limited to, conductive rubber, conductive fiber cloth, AgCl-containing conductive adhesive, conductive filaments, and conductive films. In some solutions, conductive rubber, conductive silicone, conductive films, conductive coatings, etc., can be used instead of conductive fiber cloth.

[0096] The protective device is located on the outside of the electrode layer. The protective device can be located on the inside or outside of the wearable device 1. Generally, the protective device can be directly attached to the wearable device 1 with adhesive. An insulating material, including but not limited to TPU film, insulating silicone, or rubber, can also be used between the wearable device 1 and the protective device 1. By using an insulating material to insulate the conductive fibers on the protective device from the wearable device 1, conductive substances on the wearable device 1, such as sweat, can be prevented from affecting the protective device.

[0097] When a protective device is provided on the outside of the wearable device 1, the outside of the protective device can also be coated with insulating glue or covered with insulating cloth to prevent conductive substances, such as the wearer's clothes soaked with sweat, from affecting the protective device.

[0098] The protective device consists of two conductive fiber cloths, one coupled to the proximal end of the wearer's arm and the other coupled to the distal end. This coupling includes direct physical contact and can also be achieved through coupling components. Furthermore, the proximal and distal ends are relative and not limited to the left or right sides of the chest; they can also be the left or right arms, etc.

[0099] Taking Example 1 as an example, in this example, the user wears the device on their chest. At this time, the first conductor 51 is located on the left side of the wearer's chest, and the second conductor 52 is located on the right side of the wearer's chest. The first conductor 51 is located closer to the heart than the second conductor 52. Because the heart is constantly beating, the potentials of the first conductor 51 and the second conductor 52 are different, thus forming a capacitor structure between them.

[0100] The shortest physical distance between two conductive fibers in the protection device is less than 15mm, because if the spacing is too large, it cannot effectively protect the electrode sheets.

[0101] The third electrode 33 and the fourth electrode 34 are generally single-layered. Materials used include, but are not limited to, conductive rubber, conductive fiber cloth, conductive adhesive containing AgCl, and cloth woven from conductive wires. The third electrode 33 and the fourth electrode 34 can be multi-layered, with insulation between different layers, and energy is transferred using coupling methods such as capacitive coupling. The third electrode 33 and the fourth electrode 34 are generally located on the inner side of the wearable device 1. When the third electrode 33 and the fourth electrode 34 are located on the outer side of the wearable device 1, holes can be provided in the wearable device 1 to allow partial contact between the third electrode 33 and the fourth electrode 34 and the wearer's skin. It should be noted that the proximal and distal ends are relative and do not refer to a specific location. The first electrode 31 is located proximal to the second electrode 32, and the third electrode 33 is located proximal to the fourth electrode 34. For example, when the device is worn on the body, the third electrode 33 is always located on the left side of the wearer's chest, and the fourth electrode 34 is always located on the right side of the wearer's chest.

[0102] No conductive fiber in the protective device forms a closed electrical circuit with the wearer's skin. For example, in Embodiment 1, only one part or one end of the first conductor 51 contacts the wearer's proximal skin, while the remaining part is electrically isolated from the wearer's skin. Only one part or one end of the second conductor 52 contacts the wearer's distal skin, while the remaining part is electrically isolated from the wearer's skin. The first conductor 51 and the second conductor 52 are also electrically isolated from each other. Therefore, the first conductor 51 and the second conductor 52 cannot form a closed electrical circuit with the wearer's skin. This description is only for the purpose of distinguishing it from the content of the patent with publication number CN221807974U.

[0103] Because of the heartbeat, there is a potential difference between the proximal and distal ends of the skin, at least at some point in time. If a wire is used to connect the proximal and distal ends of the skin of an organism, a closed electrical circuit with a small current is formed. Any conductive fiber in the protective device is either completely electrically isolated from the wearer's skin, or only one end is in contact with the wearer's skin; therefore, the conductive fiber can be considered not to form a closed electrical circuit with the wearer's skin.

[0104] The proximal and distal ends are relative terms. Taking a human as an example, the proximal and distal ends are not limited to the left and right sides of the chest; they can also be the left and right arms, etc.

[0105] External charges can be static electricity generated by friction between the wearer's clothing and the wearing device 1, or between pieces of clothing, or charges present in the wearer's surroundings. Without protective devices, these charges can interfere with the electrical signals on the electrode plates. For example, static electricity generated by friction between the wearer's clothing and the wearing device 1 during movement can interfere with the electrical signals on the electrode plates. In this article, external charges are sometimes also referred to as external interference.

[0106] In this text, "obstruction" refers to the overlapping of the projections of two conductors. For example, if the first conductor 51 obstructs the first electrode 31, then the projections of the first conductor 51 and the first electrode 31 will at least partially overlap, including the case where the entire projection of the first electrode 31 falls within the projection area of ​​the first conductor 51. "Overlap" has a similar meaning. For example, if at least part of the projection of the first conductor 51 falls within the projection of the second conductor 52, and if at least part of the first conductor 51 is outside the second conductor 52, then there is an overlapping area between the first conductor 51 and the second conductor 52. Generally, the conductive fiber cloth constituting the protective device should completely obstruct the electrode sheets. For example, the first conductor 51 should completely obstruct the first electrode 31, and the second conductor 52 should completely obstruct the second electrode 32. In this case, the protective device provides optimal protection for the electrical signals on the electrode sheets. If the conductive fiber cloth does not completely obstruct the electrodes, external charges such as static electricity may directly couple with the first electrode 31 and the second electrode 32, thereby affecting the electrical signals on the electrode sheets.

[0107] It should also be noted that, as in the patent with publication number CN221807974U, although a protective device, namely a first conductive fiber cloth, is also provided on the outer side of the electrode layer, this first conductive fiber cloth is insulated from the electrode layer, with one end in contact with the wearer's proximal end and the other end in contact with the wearer's distal end. When there is a potential difference between the proximal and distal ends, the first conductive fiber cloth can generate a microcurrent, and the generated microcurrent changes with the potential change between the proximal and distal ends. In this solution, the protective device can reduce the interference of external charges on the electrical signals on the electrode layer. However, since the first conductive fiber cloth of the protective device forms a closed circuit with the wearer's skin, when there is an external charge, such as when the wearer moves, static electricity is generated by friction between their clothing and the wearing device 1, especially during vigorous exercise in dry weather. The generation and release of static electricity will cause interference signals to be generated on the aforementioned first conductive fiber cloth, thereby changing the current in the closed circuit formed by the first conductive fiber cloth and the skin. This current change will further interfere with the electrical signals on the first electrode 31 and the second electrode 32. In this design, the first conductor 51 and the second conductor 52 on the protective device form a capacitor structure. Therefore, when the wearer moves in dry weather, the generation and release of static electricity have relatively less interference with the first electrode 31 and the second electrode 32. Thus, Embodiment 5 is superior to the design in patent CN221807974U and is the preferred embodiment.
