[0030] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0032] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0034] Existing bioelectrical signal detection devices are bulky and have complex testing procedures, unlike devices such as blood pressure monitors that are small enough for home use. They also lack the portability and real-time measurement capabilities of wearable devices like blood pressure watches and wristbands. Therefore, data monitoring is inconvenient, making it impossible to monitor users' bioelectrical signal data over long periods and collect sufficient data for health indicator collection and big data / AI analysis.

[0035] To address the above problems, this invention proposes a bioelectric signal detection module 100.

[0036] Please combine Figures 1 to 3 The bioelectric signal detection module 100 of this embodiment includes a housing 1, a circuit board 2, a detection electrode group 3, and a patch 4. The circuit board 2 is installed inside the housing 1. The detection electrode group 3 is installed on one side of the housing 1 and is electrically connected to the circuit board 2. The patch 4 is installed on the side of the housing 1 where the detection electrode group 3 is located, and is disposed to avoid the detection electrode group 3. The patch 4 is used to adhere tightly to the user's body surface so that the detection electrode group 3 contacts the user's body surface and acquires the user's bioelectric signal, and sends the bioelectric signal to an external device through the circuit board 2.

[0037] In the technical solution of this invention, the bioelectric signal detection module 100 sets up a circuit board 2 inside the housing 1 and electrically connects the detection electrode group 3 to the circuit board 2. The detection electrode group 3 contacts the user's body surface to acquire the user's bioelectric signal. A patch 4 achieves stable adhesion to the user's body surface, thereby realizing the detection of the user's bioelectric signal. The detection module of this invention does not require a bulky device; from an external perspective, it consists only of the housing 1 and the patch 4, resulting in a more compact structural design and significantly reduced size. This achieves miniaturization and portability, allowing integration into bioelectric signal detection devices, such as wearable devices, to achieve long-term real-time measurement of bioelectric signals. This enables the collection of sufficient bioelectric signals for big data and AI analysis of health indicators, improving the accuracy of health monitoring and rehabilitation treatment assessment.

[0038] Please combine Figure 5 and Figure 6 In one embodiment, the bioelectrical signal includes skin electrical signal and nerve electrical signal. The detection electrode group 3 includes a skin electrical response electrode 31 for acquiring the user's skin electrical signal, a nerve electrical signal electrode 32 for acquiring the user's nerve electrical signal, and a ground electrode 33. The skin electrical response electrode 31, the nerve electrical signal electrode 32, and the ground electrode 33 are all electrically connected to the circuit board 2. The skin electrical response electrode 31 and the nerve electrical signal electrode 32 are arranged at intervals.

[0039] The detection electrode group 3 is further refined into skin conductance response (GSR) electrodes 31 and electroneurogram (ENG) signal electrodes 32, which can respectively collect GSR signals and ENG signals. This expands the application range of the detection module, enabling the device to not only reflect emotional stress states but also be used in various health scenarios such as muscle function analysis and motor control monitoring. Furthermore, the clear division of labor and spacing between the different electrodes effectively reduces interference between signals, improves the independence and purity of the collected data, and thus enhances the accuracy and reliability of the final analysis results.

[0040] Furthermore, there are two neural electrical signal electrodes 32, which are spaced apart on both sides of the patch 4 along the first direction. The skin electrical response electrode 31 is disposed between the two neural electrical signal electrodes 32, and the ground electrode 33 is disposed between the skin electrical response electrode 31 and the two neural electrical signal electrodes 32 to separate the skin electrical response electrode 31 from the two neural electrical signal electrodes 32.

[0041] The grounding electrode 33 is positioned between the skin conductance electrode 31 and the two neural electrical signal electrodes 32, acting as a "shield" to effectively block electrical interference or crosstalk between the two types of signals, ensuring the spatial and electrical independence of the GSR and ENG signals and improving signal quality. By rationally distributing multiple electrodes in the first direction of the patch 4, the contact area with the subject's skin surface is maximized within a limited area, improving the efficiency of bioelectrical signal acquisition. At the same time, electrode overlap or chaotic layout is avoided, making the entire module more suitable for integration into small wearable devices such as patch structures and wristbands.

[0042] Specifically, each neural electrical signal electrode 32 includes a neural electrical signal positive electrode 321 and a neural electrical signal negative electrode 322 spaced apart along the second direction. The skin electrical response electrode 31 includes a skin electrical response positive electrode 311 and a skin electrical response negative electrode 312 spaced apart along the second direction. The grounding electrode 33 includes a grounding positive electrode 331 and a grounding negative electrode 332 spaced apart along the second direction. Both the grounding positive electrode 331 and the grounding negative electrode 332 are U-shaped and have their openings facing opposite directions. The grounding positive electrode 331 surrounds the skin electrical response positive electrode 311 to separate the skin electrical response positive electrode 311 from the two neural electrical signal positive electrodes 321. The grounding negative electrode 332 surrounds the skin electrical response negative electrode 312 to separate the skin electrical response negative electrode 312 from the two neural electrical signal negative electrodes 322.

[0043] Setting the positive and negative electrodes along the second direction helps capture the potential difference changes of nerve electrical signals or skin electrical signals in that direction, improving the sensitivity to changes in movement, tension, etc., making it suitable for scenarios such as motion trajectory analysis and muscle activity direction recognition. At the same time, by setting U-shaped grounded positive electrode 331 and grounded negative electrode 332, which surround the skin electrical response positive electrode 311 and skin electrical response negative electrode 312 respectively, and completely separating them from the nerve electrical signal positive electrode 321 and nerve electrical signal negative electrode 322 on the left and right sides, it can effectively reduce electromagnetic coupling or crosstalk between adjacent electrodes, improve the independence and stability of the signal, and ensure that the skin electrical response electrode 31 and the nerve electrical signal electrode 32 do not affect each other when measured in parallel.

[0044] Please combine Figure 3 and Figure 5 In one embodiment, the detection electrode group 3 is arranged with a plurality of contacts 34 on the side facing the patch 4. The contacts 34 are used to contact the user's body surface and acquire the user's bioelectrical signals.

[0045] Multiple contacts 34 make multi-point contact with the skin surface, which can significantly improve the detection area and signal acquisition stability, and maintain continuous and stable signal input even when the user moves or the skin sweats. The array of contacts 34 can achieve more precise spatial potential detection, making it easier to capture local changes and fluctuations in electrical signals, thereby more accurately acquiring changes in skin electrical signals and nerve electrical signals.

[0046] In one embodiment, the patch 4 is stacked on the side of the housing 1 where the detection electrode group 3 is located, and the patch 4 has an opening 41 at the position corresponding to the detection electrode group 3. Multiple contacts 34 on the detection electrode group 3 pass through the opening 41 to contact the user's body surface to obtain the user's bioelectrical signal.

[0047] The contact 34 passes through the patch 4, and all of the detection electrode group 3 are located on the side of the patch 4 facing the housing 1, which reduces the overall thickness of the detection module and the volume of the detection module. At the same time, the presence of the clearance 41 avoids the interference and influence of the patch 4 on the contact 34, and improves the stability and accuracy of the contact 34 in detecting bioelectric signals.

[0048] Specifically, the patch 4 itself can be made of flexible, skin-friendly materials, such as bio-adhesive tape, which can better conform to the curvature of human skin, enhance the wearing experience, avoid the pressure or slippage of rigid structures on the skin, and thus enhance the continuity of signal acquisition.

[0049] Please combine Figure 2 and Figure 6 Furthermore, the shape of the clearance opening 41 is adapted to the shape of the detection electrode group 3, so that the patch 4 and the detection electrode group 3 fit tightly together. The patch 4 can wrap around the outer periphery of the detection electrode group 3, allowing only the contact 34 to pass through the clearance opening 41, avoiding unevenness such as protrusions at the connection between the two, and improving the comfort of the patch 4 when it is applied to the user's body surface.

[0050] It should be noted that the detection electrode group 3 includes a skin electrical response electrode 31, a nerve electrical signal electrode 32, and a ground electrode 33. Therefore, the clearance port 41 is also divided into three clearance areas, which correspond to the skin electrical response electrode 31, the nerve electrical signal electrode 32, and the ground electrode 33, respectively, and are adapted to the shapes of the skin electrical response electrode 31, the nerve electrical signal electrode 32, and the ground electrode 33, respectively.

[0051] Please combine Figure 2 , Figure 3 and Figure 5In one embodiment, the housing 1 includes a first housing 11 and a second housing 12. The second housing 12 is installed on one side of the first housing 11 and surrounds the first housing 11 to form a mounting cavity 13. The side of the second housing 12 away from the first housing 11 forms a mounting groove 121. The groove opening of the mounting groove 121 faces the patch 4. A through hole 122 is provided on the side wall of the mounting groove 121 opposite to the groove opening. The detection electrode group 3 is installed in the mounting groove 121, and a connecting post 35 is provided on the side of the detection electrode group 3 facing the first housing 11, which passes through the through hole 122 and is electrically connected to the circuit board 2.

[0052] The detection electrode assembly 3 is installed through the mounting slot 121, and the mounting slot 121 is located on the side of the second housing 12 away from the first housing 11. This ensures that the detection electrode assembly 3 does not occupy too much longitudinal space, reducing the overall thickness of the detection module. At the same time, it can also separate the detection electrode assembly 3 from the circuit board 2. Interference between the two is avoided only by the connecting post 35 passing through the through hole 122, ensuring the stability of the detection electrode assembly 3.

[0053] In one embodiment, a fixing hole 21 is provided on the circuit board 2, and a battery is inserted through the fixing hole 21. The two opposite sides of the battery abut against the first housing 11 and the second housing 12, respectively, so that the battery is fixed in the mounting cavity 13. The battery is used to supply power to the circuit board 2 and to supply power to the detection electrode group 3 through the circuit board 2.

[0054] In traditional designs, batteries are typically stacked above or below the circuit board 2, increasing the module's thickness. In this invention, the battery passes through the fixing hole 21 in the circuit board 2, effectively utilizing the original space of the circuit board 2. This allows the battery to be embedded within the planar area of ​​the circuit board 2, significantly reducing the overall thickness and making the device thinner and lighter. This facilitates integration into wearable devices that fit against the skin, such as wristbands and watches, improving the user's wearing experience. The battery abuts against the first housing 11 and the second housing 12 on both sides, reliably securing it within the mounting cavity 13 through double-sided positioning. This prevents loosening or dislocation caused by external forces such as vibration or shaking, improving the overall mechanical strength and shock resistance of the device.

[0055] Please combine Figure 2 and Figure 7 In one embodiment, conductive electrodes 14 electrically connected to the circuit board 2 are provided on the inner walls of the first housing 11 and the second housing 12 facing the mounting cavity 13. The conductive electrodes 14 are made by LDS process, and each conductive electrode 14 forms a contact area that is electrically in contact with the positive or negative electrode of the battery. The contact area on the first housing 11 is connected to one of the positive or negative electrodes of the battery, and the contact area on the second housing 12 is connected to the other of the positive and negative electrodes of the battery.

[0056] Compared to the traditional method of achieving electrical connection through metal springs, battery holders, or flexible cables, this solution uses LDS (laser direct forming) technology to directly form the conductive electrode 14 on the inner wall of the first housing 11 and the second housing 12. This allows for direct connection with the two poles of the battery and the circuit board 2, thereby eliminating the need for additional connection structures and wiring space. This further reduces the structural gap between the battery, the circuit board 2, and the housing 1, resulting in a further reduction in the overall module thickness and making it easier to design miniaturized wearable devices.

[0057] This invention also provides a bioelectric signal detection device, which utilizes the aforementioned bioelectric signal detection module 100. The specific structure of the bioelectric signal detection module 100 is as described in the above embodiments. Since this bioelectric signal detection device employs all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here. Specifically, the bioelectric signal detection device can be a wearable smart device such as a smartwatch or smart glasses, or it can be a terminal device electrically connected to the bioelectric signal detection module 100. The terminal device can be used to acquire the skin conductance response signals and nerve electrical signals detected by the bioelectric signal detection module 100, thereby performing statistical analysis on the user's health status.

[0058] The above are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made under the concept of the present invention using the contents of the specification and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
