Description

Technical Field

[0001] The present application relates to the technical field of wearable devices, sensors and intelligent monitoring devices, and in particular to a wearable accessory and an intelligent monitoring device. Background Art

[0002] Currently, wearable devices like smartwatches typically use ion-selective electrodes (e.g., built-in) to detect biomarkers in sweat (such as sodium and potassium ions). However, these electrodes are susceptible to impurities and dirt in sweat, leading to signal distortion or failure. To maintain the accuracy and reliability of the electrodes, users need to regularly clean and maintain them with specialized cleaning and maintenance tools, which not only increases operational complexity but can also temporarily disable the device.

[0003] In addition, the aforementioned ion-selective electrodes typically only contact the skin through a portion of the surface, which means that the amount of sweat that can be collected is very limited. This localized contact method allows the electrodes to only obtain a small amount of sweat samples, thereby limiting the amount of sweat samples collected, resulting in an inability to accurately reflect the biomarker concentration in the entire sweat, thereby affecting the reliability of sweat detection. Due to the limited contact area, the contact between the electrode and the skin may be unstable, especially when the user is active, which may cause the electrode to shift or lose contact, resulting in data fluctuations or loss, further reducing the reliability of the monitoring results.

[0004] Therefore, when users of smart watches wear them for a long time, it is difficult to strike a balance between maintainability and reliability. Utility Model Content

[0005] The purpose of the embodiments of the present application is to provide a wearable accessory and an intelligent monitoring device to improve the problem of difficulty in balancing maintainability and reliability.

[0006] In a first aspect, an embodiment of the present application provides a wearable accessory, which is woven from fibers including flexible sweat sensor fibers and textile fibers; wherein the flexible sweat sensor fibers are used to detect biomarkers in the sweat produced by the user's skin, and transmit the obtained detection results to a wearable device to which the wearable accessory is connected.

[0007] In implementing the above solution, the flexible sweat sensor fibers are more resistant to impurities and dirt in sweat, making them less susceptible to contamination and more durable. Furthermore, the wearable accessory is woven from fibers including the flexible sweat sensor fibers and textile fibers. This woven structure eliminates the need for specialized cleaning and maintenance tools for regular cleaning and maintenance, effectively reducing the need for cleaning operations and improving the maintainability of the wearable accessory. Furthermore, compared to conventional ion-selective electrodes, which typically contact the skin only through a portion of the smartwatch body, the woven structure of the wearable accessory (e.g., a smartwatch strap) can cover a larger skin contact area, allowing for the collection of more representative sweat samples, thereby improving monitoring accuracy and reliability. Furthermore, by weaving the flexible sweat sensor fibers into different areas of the wearable accessory, simultaneous monitoring in different areas is achieved. This multi-point monitoring approach effectively reduces the impact of environmental factors (such as loss of sensor contact due to user activity) on monitoring results, even during intense user activity, further improving monitoring reliability. Therefore, even if the user of the smart watch wears it for a long time, this wearable accessory can be easily cleaned, maintained and kept in good contact, thus taking into account both ease of maintenance and reliability.

[0008] In an optional implementation of the first aspect, a flexible sweat sensor fiber includes an ion-selective membrane and an electrochemical sensor, wherein the ion-selective membrane encapsulates the electrochemical sensor; the ion-selective membrane is configured to allow electrolytes in the biomarker to pass through and reach the electrochemical sensor; and the electrochemical sensor is configured to detect the electrolyte concentration in the biomarker through an electrochemical reaction. In the implementation of this solution, the ion-selective membrane exhibits specific selectivity, allowing only specific ions in the electrolyte (e.g., sodium ions Na+ or potassium ions K+) to pass through while blocking other substances. This allows the electrochemical sensor to detect the concentration of specific ions. This non-invasive method of obtaining electrolyte concentration information through sweat is more convenient and faster than blood testing, reduces user discomfort, and makes this type of sensor suitable for long-term wear and continuous health monitoring applications.

[0009] In an optional implementation of the first aspect, the flexible sweat sensor fiber includes a sensor for detecting sodium ion concentration and / or a sensor for detecting potassium ion concentration. In implementing this solution, by using different sensors to simultaneously monitor multiple electrolytes, more comprehensive multi-parameter physiological information can be obtained. This multi-parameter monitoring can provide a more complete picture of health status and facilitate early detection of potential health issues.

[0010] In an optional implementation of the first aspect, the wearable accessory may include a contact region and a non-contact region, the contact region and the non-contact region being connected by a braided connection; the density of the flexible sweat sensor fibers in the contact region is higher than that in the non-contact region. In implementing this solution, by setting the density of the flexible sweat sensor fibers in the contact region higher, the chemical composition and biophysical properties of sweat can be more effectively captured and analyzed, thereby increasing the sensitivity of sweat detection in the contact region. Furthermore, a higher fiber density means more flexible sweat sensor points, which helps improve the signal-to-noise ratio and makes the information data extracted from sweat more reliable. Accordingly, the density of the flexible sweat sensor fibers in the non-contact region is set lower. This is because flexible sweat sensor fibers are generally more expensive than textile fibers. Therefore, the density of textile fibers in the non-contact region can be set lower, effectively saving some sensor costs and reducing overall weight. Therefore, setting the density of the flexible sweat sensor fibers in the contact region higher than that in the non-contact region can effectively reduce overall weight while maintaining sweat detection sensitivity.

[0011] In an optional implementation of the first aspect, the wearable accessory may include an inner contact layer and an outer protective layer, the outer protective layer covering the inner contact layer; the density of the flexible sweat sensor fibers in the inner contact layer is higher than that in the outer protective layer. In implementing this solution, by setting the density of the flexible sweat sensor fibers in the inner contact layer to be higher, even if some sensor fibers become damaged and unusable, data collected by sensor fibers at a similar distance can be used to approximate their replacement, ensuring accurate sweat data collection when in contact with the skin, thereby improving data collection efficiency and sensitivity.

[0012] In an optional implementation of the first aspect, when the wearable accessory is worn, the density of the flexible sweat sensor fibers in areas with high sweat gland density is higher than that in areas with low sweat gland density. In the implementation of the above solution, providing a higher density of flexible sweat sensors means that more data points can be collected, which helps to improve the overall quality of the signal data and the sweat monitoring effect. Therefore, by concentrating the sensors in areas with dense sweat glands, the limited number of sensors can be more effectively utilized, ensuring the best data quality in key locations without the need to evenly distribute the sensors throughout the wearable device. This solution can maximize the sweat monitoring effect without increasing the overall cost.

[0013] In an optional implementation of the first aspect, the wearable accessory is formed by alternating weaving of flexible sweat sensor fibers and textile fibers. In this implementation, alternating weaving of the flexible sweat sensor fibers and textile fibers allows for a tight integration of the two fibers, resulting in a seamless appearance and reducing the discomfort associated with traditional add-on sensors. This seamless integration helps improve the overall durability and reliability of the device and reduces the risk of damage from external forces. Furthermore, the alternating weaving ensures uniform distribution of the sensors throughout the fabric, ensuring consistent and comprehensive data collection.

[0014] An optional implementation of the first aspect further includes: a piezoelectric film sensor disposed within the wearable accessory and electrically connected to the wearable device; and the piezoelectric film sensor is configured to collect heart rate data. In implementing this solution, combined with the aforementioned biomarker detection of user sweat, both biomarker and heart rate data can be monitored simultaneously. This multimodal data collection method provides more comprehensive health and activity data, enhancing overall monitoring capabilities.

[0015] In an optional implementation of the first aspect, a wearable accessory is woven with a chamber, within which a piezoelectric film sensor is disposed, and the chamber is positioned in the user's skin near an artery. In this implementation, by placing the piezoelectric film sensor within a specific chamber, external noise and other non-correlated signals can be effectively isolated, thereby improving the signal-to-noise ratio of the measurement. This allows reliable physiological data to be obtained even in noisy environments, thereby improving the quality of physiological data collection.

[0016] In an optional implementation of the first aspect, the piezoelectric film sensor is disposed within the wearable accessory, near an inner surface. In this implementation, the piezoelectric film sensor is disposed within the wearable accessory, near an inner surface, ensuring a certain degree of isolation and close proximity between the piezoelectric film sensor and the user's skin. This enables real-time detection of minute pressure changes, thereby maintaining the sensitivity of the piezoelectric film sensor.

[0017] In an optional implementation of the first aspect, an airbag is further provided within the wearable accessory, and the airbag is configured to push the piezoelectric film sensor toward the inner surface of the wearable accessory when inflated. During implementation of the above solution, the airbag provides uniform pressure distribution between the skin and the sensor, ensuring more stable contact between the sensor and the skin, reducing the probability of data fluctuations caused by poor contact between the sensor and the skin, and thus improving signal quality and consistency. Furthermore, when the airbag inflates, it pushes the piezoelectric film sensor toward the inner surface of the wearable accessory. This allows the airbag to inflate and increase pressure to maintain good contact when the user is moving, while providing lower pressure when the user is stationary, reducing discomfort caused by compression. It also reduces noise caused by unstable contact between the sensor and the skin, thereby improving the signal-to-noise ratio of the data.

[0018] In an optional implementation of the first aspect, an automatic air pump is further provided inside the wearable accessory, and the automatic air pump is connected to the airbag ventilation; the automatic air pump is used to inflate and deflate the airbag. During the implementation of the above solution, the airbag is inflated and deflated by the automatic air pump so that when the airbag is inflated, the contact point between the piezoelectric film sensor and the user's skin is compressed. By precisely controlling the pressure of the airbag, the contact point between the piezoelectric film sensor and the skin can be ensured to remain consistent and stable, thereby improving the accuracy and consistency of data acquisition. In addition, dynamic pressure regulation can also help eliminate data fluctuations caused by skin movement or deformation, thereby improving the reliability of the user's physiological data monitoring.

[0019] In an optional implementation of the first aspect, the wearable accessory is provided with a flexible raised structure on its surface, and the piezoelectric film sensor is disposed within the flexible raised structure. In this implementation, the flexible raised structures provided on the wearable accessory's surface are relatively soft and form a close fit with the skin, reducing pressure and discomfort. Furthermore, the piezoelectric film sensor disposed within the flexible raised structure improves wearing comfort while ensuring good contact between the piezoelectric film sensor and the skin.

[0020] In an optional implementation of the first aspect, the wearable accessory further includes an electrical connection assembly for establishing an electrical connection between the flexible sweat sensor fibers and the wearable device. In this implementation, connecting the flexible sweat sensor fibers to the wearable device via the electrical connection assembly reduces signal attenuation and interference, thereby improving data accuracy and reliability.

[0021] In an optional implementation of the first aspect, the electrical connection component is a conductive fiber, one end of which is used to be woven and connected to the flexible sweat sensor fiber and the textile fiber; the other end of the conductive fiber is led out from the wearable accessory to the electrical connection point for electrical connection to the electrical interface of the wearable device. In the implementation of the above solution, because the conductive fiber is combined with the flexible sweat sensor fiber and the textile fiber by weaving, the entire fabric has higher flexibility and stretchability, and the woven connection of the conductive fiber with the flexible sweat sensor fiber and the textile fiber makes the entire system more integrated. Furthermore, the conductive fibers connected by weaving can provide stable electrical connections in multiple directions, reducing the poor contact problems that may exist in traditional point-to-point connections.

[0022] In an optional implementation of the first aspect, the electrical interface connecting the conductive fiber to the wearable device is a magnetic interface or a flexible pin interface. In implementing this solution, both interface types allow for greater design flexibility in the wearable device, adapting to different usage scenarios and user needs. For example, the magnetic interface can be designed to rotate 360 ​​degrees to accommodate different user wearing habits, thereby increasing the flexibility of the wearable accessory's usage scenarios.

[0023] In an optional implementation of the first aspect, the device further includes: a connector module; one end of the connector module is interconnected with one end of the conductive fiber, and the other end of the connector module is used to connect to the wearable device. During the implementation of the above solution, the connector module enables the wearable accessory to be quickly connected or disconnected from the device, achieving plug-and-play convenience. Users can replace or upgrade accessories without the help of professionals. In addition, the connector module can optimize electrical connections, reduce signal attenuation and interference, and improve the stability and efficiency of data transmission.

[0024] In an optional implementation of the first aspect, it also includes: a signal amplification module and a filter module, the signal amplification module and / or the filter module are arranged inside the wearable accessory; the signal amplification module is used to amplify and enhance the concentration change signal of the biomarker to obtain an amplified enhanced signal; the filter module is used to filter and reduce the noise of the amplified enhanced signal. In the implementation process of the above scheme, through modular design, the above-mentioned signal amplification module and filter module can be upgraded or replaced as independent components, which improves the maintainability and upgrade flexibility of the wearable accessory. In addition, the filter module can effectively suppress external interference signals, such as electromagnetic interference, motion artifacts, etc., to ensure the accuracy of the monitoring results.

[0025] In an optional implementation of the first aspect, the signal amplification module and the filter module are both wrapped with a sealing protective layer, a waterproof protective layer and / or a wear-resistant protective layer. During the implementation of the above solution, the sealing protective layer can prevent dust and tiny particles from entering the interior of the module, reducing wear and pollution, thereby extending the service life of the module. The waterproof protective layer enables the module to operate normally in a humid environment and can even be used in water, which is particularly important for monitoring during exercise or swimming. The wear-resistant protective layer can protect the module from friction and impact in daily use, maintaining the integrity and functionality of the module.

[0026] Secondly, embodiments of the present application provide an intelligent monitoring device comprising: a wearable device and the wearable accessory described above; a microcontroller disposed within the wearable device; and the microcontroller configured to acquire and process detection results collected by the flexible sweat sensor fibers in the wearable accessory. In implementing the above solution, by combining the wearable device and the flexible sweat sensor fibers within the intelligent monitoring device, and by having the microcontroller acquire and process the detection results, a highly integrated monitoring system is achieved, improving the convenience of data monitoring and acquisition.

[0027] In an optional implementation of the second aspect, it further includes: an optical sensor; and a microcontroller for determining the heart rate based on the heart rate data acquired by the optical sensor and the heart rate data acquired by the piezoelectric film sensor in the wearable accessory. In the implementation of the above solution, the heart rate is jointly determined by the data results of the optical sensor and the piezoelectric film sensor. This multi-sensor method of jointly determining the heart rate can provide more comprehensive information, because the optical sensor is sensitive to changes in skin color, and the piezoelectric film sensor is sensitive to mechanical vibration. The combination of the two can complement each other, reducing the limitations of a single sensor under specific conditions, thereby enabling the smart monitoring device to more accurately analyze the user's personalized health data, thereby improving the accuracy of heart rate data collection as well as the accuracy of blood pressure, HRV, stress, fatigue status, and exercise intensity.

[0028] In an optional implementation of the second aspect, the intelligent monitoring device is a smart watch or a smart bracelet. In the implementation of the above solution, multiple sensors are integrated into a small device such as a smart watch or a smart bracelet, which not only achieves miniaturization of the device but also maintains its portability.

DETAILED DESCRIPTION

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. It should be understood that the drawings in the embodiments of the present application are only for the purpose of illustration and description and are not intended to limit the scope of protection of the embodiments of the present application. In addition, it should be understood that the schematic drawings are not drawn to scale.

[0044] In addition, the described embodiments are only a portion of the embodiments of the present application, rather than all embodiments. The components of the embodiments of the present application generally described and shown in the accompanying drawings can be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed embodiments of the present application, but rather merely represents selected embodiments of the embodiments of the present application.

[0045] It should be understood that in the description of the embodiments of this application, the term "and / or" merely describes an association relationship between associated objects, indicating that three possible relationships exist. For example, A and / or B can represent three situations: A exists alone, A and B exists simultaneously, and B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship. The term "at least one" refers to one or more, while "a plurality" refers to two or more (including two).

[0046] See Figure 1 A schematic diagram of one structure of a wearable accessory provided by an embodiment of the present application is shown. The wearable accessory 100 (such as a smartwatch strap or a smart bracelet wristband) may include: flexible sweat sensor fibers 110 and textile fibers 120. In other words, the wearable accessory is formed by weaving fibers including the flexible sweat sensor fibers and textile fibers. This structure allows for ample air circulation, allowing sweat to evaporate more easily through these gaps, reducing the possibility of sweat accumulation between the skin and the wristband and the risk of skin allergic reactions caused by prolonged contact, thereby improving wearer comfort and breathability. In addition, because the entire woven structure contains sensor fibers, the contact area with the skin is large. Therefore, even if some local areas are unable to contact due to strenuous user activity or contamination, other areas can still function normally, and the overall performance is not significantly affected. Therefore, this multi-point monitoring method can effectively reduce the impact of external environmental factors (such as local sensor loss of contact due to user activity) on the monitoring results, further improving the reliability of monitoring.

[0047] It's understandable that since flexible sweat sensor fibers are already incorporated into wearable accessories (e.g., smartwatch straps), they're not required in wearable devices (e.g., smartwatch bodies). This approach effectively reduces the manufacturing cost of wearable devices like smartwatches while also conserving internal space and reducing weight. This results in a more evenly distributed weight distribution within the smartwatch, thereby enhancing wearing comfort.

[0048] The flexible sweat sensor fibers are used to detect biomarkers in sweat produced by a user's skin and transmit the detection results to a wearable device connected to the wearable accessory. Biomarkers are chemical or biological indicators detected through sweat testing and are typically associated with the user's physical health or physiological state. These biomarkers may include electrolytes (such as sodium, potassium, calcium, and magnesium ions), metabolites (such as glucose, lactate, and amino acids), hormones (such as cortisol and adrenaline), and / or microbial metabolites in sweat. Changes in the concentration of these electrolytes can reflect the body's electrolyte balance.

[0049] For ease of understanding and explanation, the following embodiments are described using electrolyte ions as an example. The flexible sweat sensor fiber filaments described above can monitor the electrolyte ion concentration in sweat, such as sodium ion concentration or potassium ion concentration. When the concentration of either of these two ions changes, the flexible sweat sensor fiber filaments can convert the potential difference analog signal caused by the ion concentration change into digital signal data, and send the digital signal data to a wearable device (such as the main body of a smart watch) to which the wearable accessory is connected, thereby allowing the wearable device to issue a warning message to avoid high-intensity exercise or labor, and not to replenish water in time, which may cause life-threatening danger.

[0050] Optionally, the above-mentioned textile fibers may be natural fibers (such as cotton, linen, bamboo fibers, etc.) and / or artificial chemical fibers (such as polyester and nylon fibers, etc.).

[0051] In implementing the above solution, the flexible sweat sensor fibers are more resistant to impurities and dirt in sweat, making them less susceptible to contamination and more durable. Furthermore, the wearable accessory is woven from fibers including the flexible sweat sensor fibers and textile fibers. This woven structure eliminates the need for specialized cleaning and maintenance tools for regular cleaning and maintenance, effectively reducing the need for cleaning operations and improving the maintainability of the wearable accessory. Furthermore, compared to conventional ion-selective electrodes, which typically contact the skin only through a portion of the smartwatch body, the woven structure of the wearable accessory (e.g., a smartwatch strap) can cover a larger skin contact area, allowing for the collection of more representative sweat samples, thereby improving monitoring accuracy and reliability. Furthermore, by weaving the flexible sweat sensor fibers into different areas of the wearable accessory, simultaneous monitoring in different areas is achieved. This multi-point monitoring approach effectively reduces the impact of environmental factors (such as loss of sensor contact due to user activity) on monitoring results, even during intense user activity, further improving monitoring reliability. Therefore, even if the user of the smart watch wears it for a long time, this wearable accessory can be easily cleaned, maintained and kept in good contact, thus taking into account both ease of maintenance and reliability.

[0052] In some comparative embodiments, sensors and processors are directly set in wearable accessories such as watch straps or wristbands, so that the processor performs preliminary processing on the data collected by the sensors. In contrast, the solution in the embodiment of the present application does not set a processor in wearable accessories such as watch straps or wristbands, but transmits the detection results to the wearable device for calculation through flexible sweat sensor fibers, effectively transferring the data processing tasks and computing loads to the wearable device, which can save the expensive processor integrated in the watch strap or wristband, thereby reducing the overall manufacturing cost. Furthermore, since the watch strap only integrates sensors without processors and other complex electronic components, it not only simplifies the design and production process of the watch strap or wristband, but also allows the watch strap to be designed to be lighter and thinner, improving wearing comfort. In addition, the fewer internal components in the wearable accessory can also make the watch strap more flexible, better adapt to the user's wrist curve, and provide a natural wearing experience.

[0053] In the implementation of the above solution, the flexible sweat sensor fibers in the wearable accessory transmit detection results to the wearable device for processing. Equipped with more powerful processors, the wearable device can execute complex algorithms and data analysis, supporting more advanced functions. Furthermore, the wearable device can combine data from other sensors (such as heart rate) for multi-parameter comprehensive analysis, providing more comprehensive health monitoring and management capabilities. Furthermore, centralizing data processing on the wearable device optimizes power consumption management. The sensors on the strap or wristband only need to collect and transmit data, reducing the strap's power consumption, thereby extending the battery life of the entire system and reducing charging frequency.

[0054] See Figure 2 A schematic diagram of one structure of a flexible sweat sensor fiber provided in an embodiment of the present application is shown. As an optional embodiment of the above-mentioned wearable accessory, the above-mentioned flexible sweat sensor fiber 110 may include: an ion-selective membrane 111 and an electrochemical sensor 112, with the ion-selective membrane 111 encapsulating the electrochemical sensor 112. The working principle of the flexible sweat sensor fiber is that when a user wears the wearable device, sweat comes into contact with the flexible sweat sensor fiber. Due to the presence of the ion-selective membrane, only specific electrolyte ions (such as sodium ions Na+ or potassium ions K+) can pass through the membrane to reach the electrochemical sensor, which then generates an electrical signal related to the concentration of these electrolyte ions.

[0055] An ion-selective membrane is used to allow electrolytes in biomarkers to pass through and reach the electrochemical sensor. Understandably, due to its specific selectivity, the ion-selective membrane only allows specific ions in the electrolyte to pass (such as sodium ions Na+ or potassium ions K+) while blocking other substances, thus enabling the electrochemical sensor to detect the concentration of specific ions. This highly selective membrane can reduce the impact of non-target ions or molecules on measurement results, thereby providing a purer and more reliable signal.

[0056] Electrochemical sensors are used to detect electrolyte concentrations in the user's sweat biomarkers through electrochemical reactions. Electrolyte concentrations include sodium ion concentration and / or potassium ion concentration. The electrochemical sensor can be a sensor based on potentiometric methods (such as ion-selective electrodes) or amperometric methods (such as enzyme electrodes), and can generate corresponding electrical signals based on changes in electrolyte concentration. This non-invasive method of obtaining electrolyte concentration information through sweat is more convenient and faster than blood testing, reducing user discomfort, making this type of sensor suitable for long-term wear and application scenarios for continuous health monitoring.

[0057] As an optional embodiment of the above-mentioned wearable accessory, the above-mentioned multiple flexible sweat sensor fibers may include: at least one sensor for detecting sodium ion concentration, and / or, at least one sensor for detecting potassium ion concentration. Changes in sodium and potassium ion concentrations are very important for assessing dehydration, electrolyte imbalance, and certain disease states. By using different sensors to monitor multiple electrolytes simultaneously, more comprehensive multi-parameter physiological information can be obtained. This multi-parameter monitoring can provide a more complete portrait of health status and help detect potential health problems early.

[0058] Optionally, the multiple flexible sweat sensor fibers described above may further include: at least one sensor for detecting calcium ion concentration, and / or, at least one sensor for detecting magnesium ion concentration, etc. Detecting a single electrolyte alone may not provide sufficient information to accurately determine health status. Combining data on sodium ions, potassium ions, calcium ions, and magnesium ions can better assess the user's fluid balance and health status. Real-time monitoring of changes in different electrolyte levels can help users adjust their diet, exercise, and other lifestyle factors to maintain optimal physical condition.

[0059] See Figure 3 A schematic diagram of the contact area and non-contact area provided in an embodiment of the present application is shown; as an optional embodiment of the above-mentioned wearable accessory, the above-mentioned wearable accessory 100 may include: a contact area 131 and a non-contact area 132, and the contact area and the non-contact area are connected by weaving. Among them, the contact area is the area that will contact the user's skin 130, and the above-mentioned non-contact area is the area that does not contact the user's skin 130, usually an area that does not need to be monitored or an area with a low sweat gland density. For example, after the strap is fixed by a pin buckle, the pin buckle divides the strap into two parts: a circular part (i.e., a contact area in a circular shape that contacts the skin) and a redundant part (i.e., a non-contact area behind the pin buckle).

[0060] The density of the flexible sweat sensor fibers in the contact area is higher than that in the non-contact area. This density represents the number of flexible sweat sensor fibers per unit area. In other words, by setting the density of the flexible sweat sensor fibers higher in the contact area, the chemical composition and biophysical properties of sweat can be more effectively captured and analyzed, thereby increasing the sensitivity of sweat detection in the contact area. Furthermore, a higher fiber density means more flexible sweat sensor points, which helps improve the signal-to-noise ratio and makes the information data extracted from sweat more reliable. Accordingly, the density of the flexible sweat sensor fibers in the non-contact area is set lower. This is because flexible sweat sensor fibers are generally more expensive than textile fibers. Therefore, the density of textile fibers in the non-contact area can be set lower, effectively saving some sensor costs and reducing the overall weight. Therefore, setting the density of the flexible sweat sensor fibers higher in the contact area than in the non-contact area can effectively reduce the overall weight while maintaining sweat detection sensitivity.

[0061] It is understood that in some embodiments, the non-contact areas may not contain flexible sweat sensor fibers. In other words, the density of the flexible sweat sensor fibers in the non-contact areas is zero, or in other words, the number of flexible sweat sensor fibers is zero. Since the non-contact areas are generally areas that do not require monitoring or areas with low sweat gland density, not placing sensors in these areas can reduce the overall weight and volume of the device and improve wearing comfort. Placing sensors only in specific contact areas can simplify the design and manufacturing process of wearable accessories. There is no need to evenly distribute sensors across the entire strap or wristband, thereby reducing the complexity of wiring and connections. This simplified design helps improve production efficiency, reduce manufacturing costs, and facilitates large-scale production and quality control. Not placing sensors in non-contact areas can retain more textile fibers, thereby improving the breathability and sweat-wicking properties of the overall fabric.

[0062] Optionally, in addition to not setting sensors in the non-contact area to increase air permeability, a special air permeable area can also be set in the contact area and / or the non-contact area. There are many ways to increase the air permeability of the above-mentioned air permeable area, including: the first is to enhance air permeability by weaving. Open-pore textiles can be artificially created during the weaving process, such as knitted fabrics or woven fabrics, so that the porosity of the air permeable area is greater than the porosity of the wear-resistant area. The porosity is the ratio of the pore volume in the area to the total fiber volume. This kind of fabric forms open pores during the weaving process, which helps air circulation. The second is to enhance air permeability by selecting material properties. The material of the air permeable area can be natural air permeable materials, artificial porous structure materials, etc. Among them, the above-mentioned natural air permeable materials include: natural fibers such as cotton, linen, and bamboo fiber. These materials themselves have more pores and can improve air permeability; artificial porous structure materials such as polyurethane foam and polyethylene foam.

[0063] See Figure 4 The diagram shows a plan view of the contact inner layer and the protective outer layer provided in an embodiment of the present application; as an optional embodiment of the wearable accessory described above, the wearable accessory 100 includes: a contact inner layer 133 and a protective outer layer 134, wherein the protective outer layer 134 covers the contact inner layer 133. Figure 5 The diagram shows a vertical cross-section of the inner contact layer and outer protective layer provided in an embodiment of the present application. The inner contact layer is the layer that contacts the user's skin 130 and can be made of a skin-friendly, soft, and breathable material. The outer protective layer 134 provides additional protection for the inner layer of the wearable accessory 100 and can be made of a wear-resistant, waterproof, and easy-to-clean material to reduce the likelihood of wearable accessory 100 being damaged by wear and tear, thereby increasing its service life.

[0064] The density of the flexible sweat sensor fibers in the contact inner layer is higher than that in the protective outer layer. This density represents the number of flexible sweat sensor fibers per unit area. That is, since the contact inner layer is in direct contact with the user's skin, increasing the density of sensor fibers within this contact area can more accurately capture the chemical and physical information in sweat, thereby improving the accuracy of monitoring data. Therefore, by setting a higher density of flexible sweat sensor fibers in this layer, even if some sensor fibers fail and become unusable, data collected by sensor fibers in a similar proximity can be used to approximate their replacement, ensuring accurate sweat data collection when in contact with the skin, thereby improving data collection efficiency and sensitivity.

[0065] Accordingly, the protective outer layer does not require a high density of sensor fibers, as its primary function is to protect the flexible sweat sensors in the inner layer and provide structural support for the wearable accessory. By reducing the density of the flexible sweat sensor fibers in the outer layer, the protective outer layer can be made thinner and more breathable, thereby improving wearer comfort. This also increases the durability of the accessory, as the outer layer is less exposed to sweat, reducing the risk of corrosion to the flexible sweat sensors.

[0066] It is understood that in some embodiments, the protective outer layer may not contain flexible sweat sensor fibers. Specifically, the density of the flexible sweat sensor fibers in the protective outer layer is zero, or the number of flexible sweat sensor fibers is zero. Similarly, omitting sensors from the protective outer layer can reduce the overall weight and volume of the device, improving wearer comfort. Placing sensors only in a specific inner layer can simplify the design and manufacturing process of wearable accessories, eliminating the need for evenly distributing sensors across the entire strap or wristband, thereby reducing the complexity of wiring and connections. This simplified design helps improve production efficiency, lowers manufacturing costs, and facilitates large-scale production and quality control.

[0067] Optionally, the wearable accessory may further include: an intermediate layer disposed between the contact inner layer and the protective outer layer; the elasticity of the intermediate layer is greater than that of the contact inner layer, and the elasticity of the intermediate layer is greater than that of the protective outer layer. The high elasticity of the intermediate layer allows the entire wearable device to better fit the user's skin or clothing, reducing displacement caused by movement, thereby providing a more stable monitoring environment. Furthermore, the highly elastic intermediate layer can deform as the user's body bends and stretches, reducing pressure points on the skin and improving comfort when worn. In addition, due to the good elasticity of the intermediate layer, it can ensure good contact between the sensor and the skin, and will not easily move out of position even during strenuous exercise, thereby ensuring the continuity and accuracy of data collection.

[0068] As an optional embodiment of the above-mentioned wearable accessory, when the wearable accessory is worn, the density of the flexible sweat sensor fibers in the area corresponding to the high sweat gland density is higher than the density in the area corresponding to the low sweat gland density. This density represents the number of flexible sweat sensor fibers per unit area. Since areas with a high sweat gland density usually produce more sweat, the sensors in these areas can access sufficient sweat samples more quickly, thereby speeding up the response speed. In addition, by setting a higher density of flexible sweat sensors, it means that more data points can be collected, which helps to improve the overall quality of the signal data and the sweat monitoring effect. Therefore, by concentrating the sensors in areas with dense sweat glands, the limited number of sensors can be more effectively utilized, ensuring the best data quality at key locations without the need to evenly distribute the sensors throughout the wearable device. This solution can maximize the sweat monitoring effect without increasing the overall cost.

[0069] It is understandable that in some embodiments, flexible sweat sensor fibers may be woven only in areas with high sweat gland density, and not in other areas. Since areas with high sweat gland density produce more sweat, sensors in these areas can access sufficient sweat samples more quickly, thereby speeding up response speed and data collection efficiency. By concentrating the flexible sweat sensor fibers in areas with high sweat gland density, monitoring in key areas can ensure more reliable and timely data, which helps to more accurately assess the user's physiological state. Concentrating sensors in areas with dense sweat glands can more effectively utilize the limited number of sensors and avoid wasting sensor resources in areas with low sweat gland density. This targeted design can maximize monitoring effects without increasing costs, thereby improving overall cost-effectiveness.

[0070] Alternatively, by combining the advantages of several of the above approaches, a highly optimized wearable accessory can be designed for more efficient, comfortable, and reliable sweat monitoring. In the inner contact areas (e.g., areas with high sweat gland density), a high density of flexible sweat sensor fibers is woven into the fabric. These sensors detect biomarkers in sweat. Conductive fibers in these inner contact areas are woven together with the flexible sweat sensor fibers, ensuring a stable electrical connection and transmitting data to the wearable device. In the inner non-contact areas (e.g., areas with low sweat gland density or where monitoring is not required), only conventional textile fibers are woven without the flexible sweat sensor fibers. This allows for more textile fibers to be retained in these areas, improving overall fabric breathability and perspiration wicking, keeping the skin dry and enhancing wearer comfort. In the contact areas with high sweat gland density, the number of flexible sweat sensor fibers is increased, resulting in a high-density sensor layout. This ensures more data points in critical areas, improving monitoring accuracy and sensitivity. Because the sensors are concentrated in areas with high sweat gland density, they can access sufficient sweat samples more quickly, speeding up response speed and data collection efficiency. In addition, the high-density sensor layout provides more data points, improving monitoring accuracy and sensitivity.

[0071] As an optional embodiment of the aforementioned wearable accessory, the wearable accessory is formed by alternating weaving of flexible sweat sensor fibers and textile fibers. By alternating weaving of the flexible sweat sensor fibers and textile fibers, the flexible sweat sensor fibers are tightly integrated with the textile fibers, achieving a seamless appearance and reducing the discomfort that may be caused by traditional add-on sensors. This seamless integration helps improve the overall durability and reliability of the device and reduces the risk of damage caused by external forces. In addition, the alternating weaving method ensures that the sensors are evenly distributed throughout the fabric, ensuring consistent and comprehensive data collection.

[0072] Optionally, the flexible sweat sensor fibers and textile fibers can be woven alternately in a one-on-one, one-on-two, two-on-one, or two-on-two arrangement. By varying the ratio of sensor fibers to textile fibers (e.g., one-on-one, one-on-two, etc.), the number of sensors per unit area can be precisely controlled, allowing sensitivity and data acquisition density to be tailored to different monitoring needs. In areas requiring high-precision monitoring, a higher sensor density can be selected; in other areas, the number of sensors can be reduced to reduce cost and weight. Furthermore, adopting a one-on-two or two-on-one arrangement increases the distance between sensors, making the placement of sensor fibers more rational and reducing the possibility of electromagnetic interference between adjacent sensors, thereby improving signal stability and reliability.

[0073] See Figure 6The vertical cross-sectional view of the piezoelectric film sensor provided in the embodiment of the present application is shown; as an optional embodiment of the wearable accessory described above, the wearable accessory 100 may further include: a piezoelectric film sensor 140; the piezoelectric film sensor is disposed inside the wearable accessory and is electrically connected to the wearable device. Figure 7 A horizontal cross-sectional schematic diagram of a piezoelectric film sensor provided by an embodiment of the present application is shown; since the piezoelectric film sensor can convert mechanical energy into electrical energy, when the user moves or the wearable device is subjected to external force, the piezoelectric film generates current. This self-powered characteristic helps to extend battery life or achieve battery-free operation of some functions. For example, during exercise, the user's movements can provide energy for the sensor itself, thereby reducing dependence on an external power source. Furthermore, the piezoelectric film can also be used to monitor the user's exercise status and physical activity level. By analyzing the generated electrical signals, information such as the number of steps and exercise intensity can be inferred.

[0074] The above-mentioned piezoelectric film sensor is used to collect heart rate data and can transmit the collected heart rate data to a wearable device so that the wearable device can convert the heart rate data into blood pressure data after receiving the heart rate data. Among them, the piezoelectric film sensor can be made of polyvinylidene fluoride (PVDF) material, which is a highly non-reactive thermoplastic fluoropolymer. In addition, combined with the above-mentioned biomarker detection of user sweat, the multimodal data collection method that can monitor biomarkers and heart rate at the same time provides more comprehensive health and activity data and enhances the overall monitoring capability. In some optional embodiments, the wearable accessory can also be made into an insole, for example, an insole woven from fibers including flexible sweat sensor fibers and textile fibers, or a layer woven from fibers including flexible sweat sensor fibers and textile fibers is added to the insole. In these embodiments, since the piezoelectric film sensor in the above-mentioned insole can sense pressure changes at different positions in the insole, this can effectively help correct gait and help improve and prevent the foot from becoming everted.

[0075] See Figure 8 A schematic vertical cross-sectional view of a chamber provided in an embodiment of the present application is shown; as an optional embodiment of the wearable accessory described above, the wearable accessory is woven with a chamber 150, within which a piezoelectric film sensor 140 is disposed. This chamber design also protects the sensor from physical damage, extending its service life. Furthermore, by placing the piezoelectric film sensor in a specific chamber, external noise and other non-correlated signals can be effectively isolated, improving the signal-to-noise ratio of the measurement. This allows reliable physiological data to be obtained even in noisy environments, thereby improving the quality of physiological data collection.

[0076] See Figure 9 The horizontal cross-sectional schematic diagram of the chamber provided in an embodiment of the present application is shown; the chamber 150 is arranged in a position close to the artery in the user's skin. Because the chamber is close to the artery, the piezoelectric film can directly sense the tiny vibrations generated by the arterial pulsation, which enables the piezoelectric film sensor to capture the heart rate more accurately. By analyzing the changes in heart rate and combining appropriate algorithms, the user's blood pressure value can be estimated, thereby providing a non-invasive and continuous way to monitor blood pressure. For patients with hypertension or people at higher risk of cardiovascular disease, this real-time blood pressure monitoring can help them better manage their health.

[0077] Optionally, the shape of the above-mentioned cavity can adapt to the curve of the user's skin. This design that adapts to the skin curve reduces the gap between the wearable device and the skin, reducing the discomfort caused by an inappropriate shape. In addition, the inner wall of the above-mentioned cavity can be made of flexible materials so that the cavity can be adaptively adjusted to a certain extent according to the skin curve of different users to achieve a personalized fit. The shape of the above-mentioned cavity that fits the user's skin allows the wearable accessory to follow the body contour more naturally, reducing friction and pressure points, thereby improving the comfort of long-term wear. When the sensor fits tightly to the skin, it can reduce the impact of external environmental factors (such as exercise and clothing friction) on signal acquisition, thereby providing more stable and accurate data. In addition, the skin-fitting design increases the stability of the wearable device, and it is not easy to shift even during strenuous exercise or daily activities.

[0078] As an optional embodiment of the aforementioned wearable accessory, the piezoelectric film sensor can be positioned inside the wearable accessory, near the inner surface. Specifically, the piezoelectric film sensor is not in direct contact with the user's skin, but is instead separated by at least one layer of material (e.g., a film or a woven fiber layer such as cloth). In this implementation, by positioning the piezoelectric film sensor near the inner surface of the wearable accessory, the piezoelectric film sensor is not only somewhat isolated from the user's skin but also very close to it. This allows for real-time detection of minute pressure changes, thereby maintaining the piezoelectric film sensor's sensitivity.

[0079] Specifically, when the wearable accessory is worn, a fiber woven layer may be provided between the piezoelectric film sensor and the user's skin. The fiber woven layer may be composed of at least one layer of fiber braid including flexible sweat sensor fibers and / or textile fibers. By providing an additional buffer between the piezoelectric film sensor and the user's skin, the discomfort that may be caused by direct contact between the sensor and the skin can be reduced. The fiber woven layer can act as a physical barrier to protect the piezoelectric film sensor from external mechanical damage, sweat corrosion, and other environmental factors, which helps to extend the service life of the piezoelectric film sensor and ensure its long-term stable operation.

[0080] See Figure 10 A schematic diagram of the arrangement of the airbag provided in an embodiment of the present application is shown; as an optional embodiment of the wearable accessory described above, the wearable accessory 100 may further be provided with an airbag 151 inside the chamber 150. The airbag 151 is configured to push the piezoelectric film sensor toward the inner surface of the wearable accessory when inflated. When the wearable accessory 100 is worn and used, the piezoelectric film sensor 140 is disposed between the airbag 151 and the user's skin 130. However, the piezoelectric film sensor 140 is not in direct contact with the user's skin 130. Instead, the piezoelectric film sensor 140 and the user's skin 130 may be separated by at least one of the aforementioned fiber woven layers. By setting up an airbag to adjust the pressure, the piezoelectric film sensor can better adapt to the skin types and body contours of different users, providing consistent and reliable monitoring results. In addition, the airbag can adjust the pressure on the skin by inflating or deflating, ensuring that the sensor and the skin always maintain appropriate contact force. Therefore, the presence of the airbag can act as a buffer layer to reduce the impact of external factors (such as movement and clothing friction) on the sensor, thereby improving the stability and accuracy of the signal collected by the piezoelectric film sensor.

[0081] Please refer to Figure 8 As an optional embodiment of the aforementioned wearable accessory, an automatic air pump 152 is also provided within the wearable accessory, which is ventilated to the airbag 151. The automatic air pump 152 can dynamically adjust the airbag pressure based on the user's activity level, skin condition, or sensor signal quality. For example, it can reduce pressure to improve comfort when the user is at rest and increase pressure to maintain good contact during exercise. This adaptive capability ensures that the sensor is always in optimal working condition, whether the user is resting or engaging in strenuous exercise.

[0082] It is understood that the aforementioned automatic air pump is used to inflate and deflate the airbag. When the airbag is inflated, it pushes the piezoelectric film sensor against the inner surface of the wearable accessory, thereby compressing the contact point between the piezoelectric film sensor and the user's skin. By precisely controlling the airbag's pressure, the contact point between the piezoelectric film sensor and the skin remains consistent and stable, thereby improving the accuracy and consistency of data acquisition. Furthermore, dynamic pressure regulation helps eliminate data fluctuations caused by skin movement or deformation, thereby improving the reliability of the user's physiological data monitoring.

[0083] As an optional embodiment of the above-mentioned wearable accessory, a flexible raised structure (not shown) is further provided inside the wearable accessory, and the above-mentioned piezoelectric film sensor can be provided inside the flexible raised structure. In the implementation process of the above-mentioned solution, by providing a flexible raised structure inside the wearable accessory and disposing a piezoelectric film sensor inside the flexible raised structure, these flexible raised structures are relatively soft and can form a close fit with the skin, thereby reducing pressure and discomfort on the skin, thereby improving wearing comfort while ensuring good contact between the sensor and the skin to ensure signal quality.

[0084] Optionally, the flexible protrusion structure can be made of flexible rubber (e.g., silicone rubber). Since flexible rubber (e.g., silicone rubber) is generally relatively inexpensive, the flexible protrusion structure is simple in design and low in cost, further optimizing resource utilization. Furthermore, it is easy to manufacture and integrate, helping to reduce overall production costs. Alternatively, the flexible protrusion structure can be made of a durable material, reducing wear caused by long-term high pressure and further extending the life of the device.

[0085] As an optional embodiment of the aforementioned wearable accessory, the aforementioned wearable accessory further includes an electrical connection assembly (not shown) for establishing an electrical connection between the flexible sweat sensor fibers and the wearable device. In implementing this solution, connecting the flexible sweat sensor fibers to the wearable device via the electrical connection assembly reduces signal attenuation and interference, thereby improving data accuracy and reliability.

[0086] As an optional embodiment of the aforementioned wearable accessory, the electrical connection component comprises a conductive fiber (not shown), one end of which is braided and connected to the flexible sweat sensor fibers and the textile fibers. Because the conductive fiber is braided together with the flexible sweat sensor fibers and the textile fibers, the overall fabric possesses greater flexibility and stretchability. Furthermore, the braided connection of the conductive fiber with the flexible sweat sensor fibers and the textile fibers further integrates the entire system. Furthermore, the braided conductive fibers provide a stable electrical connection in multiple directions, reducing the potential for poor contact in traditional point-to-point connections.

[0087] The other end of the conductive fiber is led out from the wearable accessory to an electrical connection point for electrical connection to the electrical interface of the wearable device. By leading the conductive fiber to the external electrical connection point, a modular connection between the sensor and the main device can be achieved, allowing users to replace or upgrade the sensor component as needed. This modular design also facilitates maintenance and repair. If a sensor fails, only the sensor module needs to be replaced without replacing the entire wearable device. Through the external electrical connection point, high-speed data transmission can be achieved, allowing the wearable device to receive and process data from the flexible sweat sensor in real time.

[0088] Optionally, the conductive fibers described above may be coated with a polymer material, a sealing protective layer, a waterproof protective layer, and / or a wear-resistant protective layer to enhance the conductive fibers' sealing, waterproofness, and wear resistance. The waterproof protective layer effectively prevents moisture from invading the conductive fibers, ensuring a stable and reliable electrical connection even in humid environments or when the user is sweating. This is particularly important for wearable devices that need to be used outdoors or in high-humidity environments, such as health monitoring wristbands used while swimming or in the rain. The wear-resistant protective layer reduces damage to the conductive fibers caused by friction and wear, extending their service life. For example, in daily use, wearable devices may be subject to friction from clothing or other objects, and the wear-resistant protective layer reduces the impact of these mechanical stresses on the conductive fibers. The sealing protective layer prevents dust, dirt, and other contaminants from entering the conductive fibers, keeping them clean and operating efficiently. This sealing also helps isolate external electromagnetic interference, improving the quality and stability of signal transmission. Therefore, by providing a sealing protective layer, a waterproof protective layer, and / or a wear-resistant protective layer, the conductive fibers can be protected from environmental factors, ensuring the normal operation of the device under various conditions, and increasing the service life and adaptability of the wearable device.

[0089] As an optional embodiment of the above-mentioned wearable accessory, the electrical interface for connecting the above-mentioned conductive fiber to the wearable device can be a magnetic interface or an elastic pin interface. The magnetic interface provides a quick and easy connection method. The user can easily connect or disconnect the wearable device from the conductive fiber without complicated operations, thereby improving the user experience. The elastic pin interface can withstand a certain degree of mechanical stress, reducing poor contact or interface damage caused by repeated plugging and unplugging, thereby improving the durability and reliability of the connection. Both types of interfaces allow the design of wearable devices to be more flexible and can adapt to different usage scenarios and user needs. For example, the magnetic interface can be designed to rotate 360 ​​degrees to adapt to the wearing habits of different users, thereby improving the flexibility of the wearable accessory usage scenarios.

[0090] As an optional embodiment of the above-mentioned wearable accessories, it also includes: a connector module (not shown); one end of the connector module is interconnected with one end of the conductive fiber, and the other end of the connector module is used to connect to the wearable device. By using a standardized connector module, wearable devices of different brands or models can be compatible with the same type of accessories, improving product interoperability. Furthermore, the connector module allows wearable accessories to be quickly connected or disconnected from the device, achieving plug-and-play convenience. Users can replace or upgrade accessories on their own without the help of professionals. In addition, the connector module can optimize electrical connections, reduce signal attenuation and interference, and improve the stability and efficiency of data transmission.

[0091] Optionally, the connector module may be a magnetic module, or a snap-on module. The magnetic connection allows users to easily connect or disconnect accessories from wearable devices without the need for precise alignment, thereby improving the user experience. The snap-on connection provides a stable physical connection that is not prone to accidental detachment and is suitable for scenarios requiring a secure connection. The snap-on design can withstand greater mechanical stress and is not easily loosened by vibration or impact, thereby improving stability and reliability.

[0092] As an optional embodiment of the above-mentioned wearable accessory, it further includes: a signal amplification module (not shown in the figure) and a filter module (not shown in the figure), and the signal amplification module and / or the filter module are arranged inside the wearable accessory.

[0093] The signal amplification module is used to amplify and enhance the biomarker concentration change signal to obtain an amplified and enhanced signal. This module can enhance the weak biomarker concentration change signal, making it clearer and less susceptible to background noise. The filter module removes clutter and noise from the signal, improving the signal-to-noise ratio and ensuring data accuracy.

[0094] The filter module is used to filter and reduce noise on the amplified and enhanced signal. The filter module can remove clutter and noise from the signal, improve the signal-to-noise ratio, and ensure data accuracy.

[0095] During the implementation of the above solution, through modular design, the above-mentioned signal amplification module and filter module can be upgraded or replaced as independent components, which improves the maintainability and upgrade flexibility of wearable accessories. In addition, the filter module can effectively suppress external interference signals, such as electromagnetic interference, motion artifacts, etc., to ensure the accuracy of the monitoring results.

[0096] As an optional embodiment of the above-mentioned wearable accessory, the signal amplification module and the filter module are both wrapped with a sealing protective layer, a waterproof protective layer and / or a wear-resistant protective layer. The sealing protective layer can prevent dust and tiny particles from entering the interior of the module, reducing wear and contamination, thereby extending the service life of the module. The waterproof protective layer enables the module to operate normally in a humid environment and can even be used in water, which is especially important for monitoring during exercise or swimming. The wear-resistant protective layer can protect the module from friction and impact in daily use, maintaining the integrity and functionality of the module.

[0097] See Figure 11 A horizontal schematic diagram of an intelligent monitoring device provided with a microcontroller according to an embodiment of the present application is shown, and Figure 12 A vertical cross-sectional schematic diagram of an intelligent monitoring device provided in an embodiment of the present application and equipped with a microcontroller is shown. This embodiment of the present application provides an intelligent monitoring device 300, comprising: a wearable device 200 and the wearable accessory 100 described above; a microcontroller 210 is disposed within the wearable device 200. The microcontroller 210 is used to obtain and process the detection results collected by the flexible sweat sensor fibers in the wearable accessory. By combining the wearable device and the flexible sweat sensor fibers in the intelligent monitoring device, and having the microcontroller obtain and process the detection results, a highly integrated monitoring system is achieved, allowing users to easily obtain various health and physiological data, thereby improving the convenience of data monitoring and acquisition.

[0098] Optionally, the use of a microcontroller enables real-time processing and feedback of test results. Users can immediately obtain information about biomarker concentrations in sweat, which is very useful for health monitoring and athletic performance analysis. Furthermore, the microcontroller can execute complex data processing algorithms (for example, adjusting exercise intensity and hydration), providing precise analysis results and helping users better understand their physical condition. Therefore, smart monitoring devices can also provide personalized recommendations and feedback based on the user's specific data, such as adjusting exercise intensity and hydration, thus enhancing the user's personalized experience.

[0099] As an optional embodiment of the above-mentioned smart monitoring device, the smart monitoring device further includes: an optical sensor (not shown); and a microcontroller for determining final heart rate data based on heart rate data acquired by the optical sensor and heart rate data acquired by a piezoelectric film sensor in a wearable accessory. The heart rate data acquired by the optical sensor can be used to calibrate the heart rate data acquired by the piezoelectric film sensor in the wearable accessory. In some scenarios, the heart rate data acquired by the piezoelectric film sensor in the wearable accessory can also be used to calibrate the heart rate data acquired by the optical sensor. The heart rate data acquired by the optical sensor and the heart rate data acquired by the piezoelectric film sensor in the wearable accessory can also be fused (e.g., weighted averaging). Determining heart rate using data from both the optical and piezoelectric film sensors provides more comprehensive information. Because optical sensors are sensitive to skin color changes, while piezoelectric film sensors are sensitive to mechanical vibration, the combination of the two can complement each other, reducing the limitations of a single sensor under specific conditions. This allows the smart monitoring device to more accurately analyze the user's personalized health data, thereby improving the accuracy of heart rate data acquisition, as well as the accuracy of blood pressure, HRV, stress, fatigue status, and exercise intensity.

[0100] As an optional implementation of the above-mentioned intelligent monitoring device, the intelligent monitoring device is a smart watch or a smart bracelet. Of course, in some scenarios, it can also be a smart armband that can monitor the user's steps, calories, heart rate and other information while running. Integrating multiple sensors into a small device such as a smart watch or bracelet not only achieves the miniaturization of the device but also maintains its portability, allowing users to monitor their health anytime and anywhere.
