The detector includes an impedance measurement component and a dehumidification component. The support layer includes a processor. Both the impedance measurement component and the dehumidification component are electrically connected to the processor. The impedance measurement component, the dehumidification component, and the processor are all disposed inside the housing. The impedance measurement component is embedded in the upper surface of the housing, and the upper surface of the impedance measurement component is parallel to or higher than the upper surface of the housing.

Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and in particular to a method and device for detecting human body composition. Background Technology

[0002] Body composition refers to the content of components such as fat, muscle, protein, and minerals in the human body. It can be used to evaluate the development, maturation, and aging of the human body and is of great significance in monitoring children's development, guiding bodybuilding and weight loss, and medical care.

[0003] Commonly used methods for body composition analysis include dual-energy X-ray absorptiometry (DEXA) and bioelectrical impedance analysis (BIA). DEXA measures the absorption and attenuation of X-rays at different energy levels as they pass through human bones and soft tissues to determine body composition. This method is highly accurate but involves radiation and is expensive. When different weak currents pass through the human body, components such as fat and muscle exhibit different electrical conductivity, resulting in varying body impedances. Therefore, BIA uses the measured impedance, combined with information such as gender, age, height, and weight, to calculate the content of various body components. BIA is a simple and convenient method, and is the primary measurement method used by professional-grade and home-use body fat scales.

[0004] The accuracy of BIA-based body composition detection depends on impedance measurement results. However, the accuracy of body impedance detection is greatly affected by the humidity of the skin surface. When users sweat on their feet and hands, or when users want to see the fat loss effect immediately after exercise or showering and want to measure their body composition, the presence of sweat or moisture on the surface of the feet and hands will result in a large impedance measurement error, leading to inaccurate body composition detection results. Summary of the Invention

[0005] This application provides a method and device for detecting human body composition, which can improve the accuracy of detecting human body composition through human body impedance.

[0006] This application provides a human body composition detection device, comprising: a housing, a support layer, and at least one detector. The detector includes an impedance measurement component and a dehumidification component. The support layer includes a processor. Both the impedance measurement component and the dehumidification component are electrically connected to the processor. The impedance measurement component, the dehumidification component, and the processor are all disposed inside the housing. The impedance measurement component is embedded in the upper surface of the housing, and the upper surface of the impedance measurement component is parallel to or higher than the upper surface of the housing. The upper surface of the impedance measurement component contacts the human body during measurement. By adding a dehumidification component to the detection device, the human body surface in contact with the impedance measurement component is dehumidified before the impedance measurement component performs human body impedance measurement. After the moisture on the human body surface is removed, the human body impedance measurement component measures the human body impedance, thereby improving the accuracy of human body impedance measurement and thus improving the accuracy of human body composition detection based on human body impedance.

[0007] In one exemplary embodiment, the detector further includes a humidity measuring component electrically connected to the processor. This humidity measuring component is embedded in the impedance measuring component, and its upper surface contacts the human body during measurement. Accordingly, when the humidity value measured by the humidity measuring component does not meet the measurement requirements of the impedance measuring component, the dehumidification component performs dehumidification. When the humidity value measured by the humidity measuring component meets the measurement requirements of the impedance measuring component, dehumidification is not required, and the impedance measuring component measures the human body impedance. This allows the detection device to dehumidify according to the actual situation, providing a better user experience.

[0008] Optionally, the upper surface of the humidity measuring component and the upper surface of the impedance measuring component are located in the same plane to ensure user comfort during measurement.

[0009] In one exemplary embodiment, the dehumidification component is an electric heating element, and the impedance measuring component, the housing, the electric heating element, and the support layer are stacked from top to bottom. Through holes are respectively formed on the impedance measuring component, the housing, and the electric heating element. The humidity measuring component is installed in one of the through holes, and its lower end is electrically connected to the support layer.

[0010] Optionally, the through hole is located at the center of the impedance measuring component and the electric heating element.

[0011] In another exemplary embodiment, the dehumidification component is a fan. The impedance measurement component, the housing, the fan, and the support layer are stacked from top to bottom. Through holes are formed in the impedance measurement component, the housing, and the fan. The humidity measurement component is installed within these through holes, and its lower end is electrically connected to the processor. Multiple ventilation holes are formed at corresponding positions on the impedance measurement component and the housing, allowing the air blown by the fan to reach the human body surface through these ventilation holes.

[0012] Optionally, the through-hole is located at the center of the impedance measurement assembly, the housing, and the fan shaft.

[0013] In another exemplary embodiment, the dehumidification component is a fan. The impedance measurement component, the housing, the fan, and the support layer are stacked from top to bottom. The impedance measurement component and the housing have through holes, and the humidity measurement component is installed in the through holes. The electrodes of the humidity measurement component and the impedance measurement component are connected to the processor through wire lead-out slots on the upper surface of the fan. Multiple ventilation holes are provided at corresponding positions on the impedance measurement component and the housing, and the air blown out by the fan reaches the human body surface through these ventilation holes.

[0014] Optionally, the through-hole is located at the center of the impedance measurement component and the housing.

[0015] In another exemplary embodiment, the dehumidification component is a drying ring, the impedance measurement component is made of a superhydrophobic conductive material, the impedance measurement component has an arc-shaped convex structure, the drying ring is arranged around the impedance measurement component, and the upper surface of the drying ring is lower than or parallel to the outer edge of the impedance measurement component, thereby forming a slope, so that water droplets on the human body surface can roll off from the top of the impedance measurement component to the drying ring, and the drying ring absorbs moisture.

[0016] Optionally, the impedance measurement component is an impedance measurement electrode, which is formed by coating the upper surface of the housing.

[0017] Optionally, the impedance measurement component is disposed within a recess in the housing.

[0018] In one exemplary embodiment, the body composition detection device also includes a pressure sensor for measuring body weight. It is understood that body weight needs to be considered when measuring body composition.

[0019] Optionally, the pressure sensor is located below the support layer.

[0020] Optionally, the upper surface of the humidity measuring component and the upper surface of the impedance measuring component are located in the same plane.

[0021] In one exemplary embodiment, the body composition detection device includes four detectors symmetrically distributed around the center of the detection device.

[0022] In one exemplary embodiment, the processor is further configured to output a first prompt message when the humidity value measured by the humidity measuring component does not meet the measurement condition requirements of the impedance measuring component. The first prompt message is used to prompt whether dehumidification should be performed. When a user confirms dehumidification based on the first prompt message is received, dehumidification is performed through the dehumidification component.

[0023] In one exemplary embodiment, the processor is further configured to control the dehumidification component to stop dehumidifying when the humidity value measured by the humidity measurement component meets the measurement condition requirements, or to control the dehumidification component to stop dehumidifying when the preset dehumidification time is reached.

[0024] A second aspect of this application provides a method for detecting body composition, applied to a body composition detection device. The device includes a dehumidification component for dehumidifying the surface of the body being measured. After dehumidification, body impedance is measured. The detection device can process the measured body impedance value to obtain body composition and output the body composition; alternatively, the detection device can send the measured body impedance value to a terminal device, which then processes the value to obtain and output the body composition. This method dehumidifies the body surface before measuring body impedance, thus improving the accuracy of body impedance measurement and consequently enhancing the accuracy of body composition detection based on body impedance.

[0025] In one exemplary manner, the humidity of the human body surface is measured before the dehumidification component dehumidifies the surface it contacts.

[0026] Optionally, after measuring the humidity of the human body surface, the body composition detection device determines whether the measured humidity value meets the measurement requirements. If the humidity value does not meet the requirements, the dehumidification component dehumidifies the surface. If the humidity value meets the requirements, the body impedance is measured directly. By detecting the humidity of the body surface and determining whether dehumidification is necessary, the user experience is improved.

[0027] Alternatively, after measuring the humidity of the human body surface, the body composition detection device can send the humidity value to a terminal device, which will then decide whether to perform dehumidification.

[0028] In one exemplary manner, during the dehumidification process of the dehumidification component on the human body surface, the humidity of the human body surface is detected. When the humidity of the human body surface meets the measurement requirements, the dehumidification is confirmed to be complete, and the measurement of human body impedance begins.

[0029] In another exemplary approach, when the preset dehumidification time is reached, dehumidification is confirmed to be complete, and human body impedance measurement begins. This dehumidification time can be preset by the system or sent by the terminal device to the human body composition detection device.

[0030] Optionally, when the humidity level on the human body surface does not meet the measurement requirements, the detection device outputs a first prompt message to indicate whether dehumidification should be performed. Upon receiving a confirmation dehumidification command from the user based on the first prompt message, the dehumidification component dehumidifies the human body surface. By interacting with the user and allowing the user to decide whether to perform dehumidification, the device can meet the needs of different users and provide a better user experience.

[0031] Optionally, when a user inputs a negative dehumidification command based on the first prompt information, a second prompt information is output, which is used to prompt the user to dry the moisture before testing.

[0032] In one exemplary embodiment, after dehumidification is complete and before measuring human body impedance, a third prompt message is output to indicate the start of human body impedance measurement. By outputting this third prompt message, the user can promptly understand the current measurement progress.

[0033] In one exemplary manner, the dehumidification component dehumidifies by one or more of the following methods: heating, blowing air, or absorbing water.

[0034] In one exemplary manner, before the dehumidification component dehumidifies the human body surface it contacts, it receives a first indication message sent by a terminal device. The first indication message is used to indicate that dehumidification should be performed before measuring human body impedance. In response to the first indication message, the dehumidification component dehumidifies the human body surface.

[0035] Furthermore, the body composition detection device also receives the dehumidification time sent by the terminal device, and confirms that dehumidification is complete when the dehumidification time is reached. Optionally, the terminal device can indicate the dehumidification time while instructing the body composition detection device to dehumidify.

[0036] In one exemplary manner, after dehumidification is completed and before measuring human body impedance, the body composition detection device receives a second indication message sent by a terminal device. This second indication message indicates that dehumidification should be stopped and that body impedance measurement should begin. The body composition detection device then begins measuring body impedance based on this second indication message.

[0037] In one exemplary manner, after processing the obtained body composition information, the body composition detection device sends the body composition information to a terminal device, which then displays the body composition information.

[0038] A third aspect of this application provides a method for human body composition analysis, comprising: a terminal device sending first instruction information to a human body composition detection device, the first instruction information instructing the human body composition detection device to dehumidify before measuring human body impedance; the terminal device receiving a human body impedance value sent by the detection device, processing the human body impedance value to obtain human body composition, and displaying the human body composition. By instructing the human body composition detection device to dehumidify the human body surface before measuring human body impedance, and only after the moisture on the human body surface is removed, the terminal device improves the accuracy of human body impedance measurement, thereby improving the accuracy of human body composition detection through human body impedance.

[0039] In one exemplary manner, before the terminal device sends the first instruction information to the body composition detection device, the terminal device displays a first prompt information, which is used to prompt whether to perform dehumidification. When the terminal device receives a confirmation dehumidification command input by the user based on the first prompt information, the terminal device sends the first instruction information to the body composition detection device.

[0040] In one exemplary embodiment, the terminal device receives the humidity value of the human body surface sent by the detection device before displaying the first prompt message. When the humidity value of the human body surface does not meet the measurement requirements, the terminal device displays the first prompt message. When the humidity value of the human body surface meets the measurement requirements, the terminal device instructs the detection device to start measuring the human body impedance.

[0041] Optionally, when the humidity value of the human body surface meets the measurement requirements, the terminal device sends a second indication message to the detection device to indicate that dehumidification should be stopped and to start measuring human body impedance.

[0042] In one exemplary manner, the terminal device sends a dehumidification time to the detection device, and the dehumidification time can be flexibly set by the user.

[0043] In one exemplary manner, when the terminal device receives a dehumidification denial command input by the user based on the first prompt information, it displays a second prompt information, which is used to prompt the user to dry the moisture and then perform the test.

[0044] In one exemplary manner, after the human body composition detection device has finished dehumidifying and before measuring human body impedance, the terminal device displays a third prompt message, which is used to prompt the start of human body impedance measurement.

[0045] A fourth aspect of this application provides a computer-readable storage medium storing computer-executable instructions that, when executed by a processor, are used to implement the human body composition detection method as described in the second or third aspect and various exemplary embodiments.

[0046] The fifth aspect of this application provides a program, which, when executed by a processor, performs the human body composition detection method as described in the second or third aspect above and in various exemplary embodiments.

[0047] The sixth aspect of this application provides a chip, including: a processing module and a communication interface, the processing module being capable of executing the human body composition detection method described in the second or third aspect and various exemplary embodiments.

[0048] The human body composition detection method and device provided in this application include a housing, a support layer, and at least one detector. The detector includes an impedance measurement component and a dehumidification component. The support layer includes a processor. Both the impedance measurement component and the dehumidification component are electrically connected to the processor. The impedance measurement component, the dehumidification component, and the processor are all disposed inside the housing. The impedance measurement component is embedded in the upper surface of the housing, and its upper surface is parallel to or higher than the upper surface of the housing. The upper surface of the impedance measurement component contacts the human body during measurement. Since surface moisture significantly affects human body impedance measurement, dehumidifying the surface moisture using the dehumidification component before measuring human body impedance, and then measuring after the surface is dry, can improve the accuracy of human body impedance measurement, thereby improving the accuracy of human body composition detection through human body impedance.

[0069] This application provides a body composition detection device and method. The body composition detection device is based on BIA (Body Fat Analyzer) for detecting body composition. BIA-based body composition detection is widely used due to its simple measurement method and ease of use. Common body composition detection devices include professional body fat scales and home-use body fat scales.

[0070] Body composition analysis (BIA) devices can be used to measure feet, hands, or both. The accuracy of BIA body composition analysis depends on impedance measurement results, which are greatly affected by skin surface moisture. When the user's feet or hands are sweaty or wet—for example, after exercise or after showering or washing—the measurement results will have a larger error.

[0071] In existing technologies, "suggestions" and "reminders" are usually added to the instruction manual of body composition detection devices, such as "avoid using after exercise or showering," reminding users to avoid using the body composition detection device when their feet or hands are sweaty or wet.

[0072] A primary application scenario for body composition analysis devices is when users use them immediately after exercise or showering. Users typically want to see the fat loss effect and measure their body composition as soon as possible after exercise or showering. Therefore, how to avoid or improve the accuracy of body composition analysis when users' feet or hands are sweaty is an urgent problem to be solved.

[0073] To address the problems of the prior art, this application provides a body composition detection device with a dehumidification function, which can remove moisture from the body contact area (hands or feet) before measuring body impedance, ensuring accurate body impedance measurement results and thus improving the accuracy of body composition detection.

[0074] This body composition detection device can be used with terminal devices such as mobile phones, tablets, wearable devices, and personal computers. The terminal devices communicate and interact with the body composition detection device through the installed body composition detection app. For example, the terminal devices can display the body composition detection results, and users can also set the body composition detection device through the terminal devices.

[0075] Figure 1 This is a schematic diagram of the external structure of a human body composition analysis device, such as... Figure 1As shown, the human body composition detection device 100 includes a housing 2, a support layer (located inside the housing, not shown in the figure), and four detectors: detector 101, detector 102, detector 103, and detector 104. The four detectors are symmetrically distributed around the center of the detection device 100.

[0076] Understandable. Figure 1 As just one example, the detection device 100 may also include more or fewer detectors.

[0077] Each detector includes an impedance measurement component and a dehumidification component. The support layer includes a processor. Both the impedance measurement component and the dehumidification component are electrically connected to the processor. The impedance measurement component, the dehumidification component, and the support layer are all housed inside the housing. The upper surface of the impedance measurement component is parallel to or higher than the upper surface of the housing, and the upper surface of the impedance measurement component comes into contact with the human body during measurement.

[0078] The dehumidification component is used to dehumidify the human body surface in contact with the impedance measurement component. The impedance measurement component measures the human body impedance after dehumidification is complete. The processor processes the human body impedance measured by the impedance measurement component to obtain the human body composition and outputs the human body composition. Alternatively, the processor sends the human body impedance measured by the impedance measurement component to a terminal device (e.g., a mobile phone) controlling the detection device 100, whereby the terminal device processes the human body impedance to obtain the human body composition and outputs the human body composition.

[0079] In use Figure 1 When the detection device 100 is used for measurement, the user's feet are placed on the device. The device is activated by the user's weight and can begin measurement. When the user is only measuring weight, they can wear shoes and socks while stepping on the device, and the position of their feet is not restricted. When the user needs to measure body composition, they must step on the device barefoot, without shoes and socks, and the position of their feet must be fixed. For example, the user's left foot steps on detectors 101 and 103, and the right foot steps on detectors 102 and 104. Otherwise, measurement cannot be performed, or the measurement results may be inaccurate.

[0080] When using the detection device 100 to measure human body composition, there are two scenarios: Scenario 1: The detection device 100 independently completes the human body composition measurement and outputs the human body composition. Scenario 2: ... Figure 2 As shown, the detection device 100 and the connected terminal device 200 cooperate to perform the measurement, and the terminal device 200 outputs the human body composition.

[0081] Taking scenario two as an example, before taking the measurement, the user first opens the body composition measurement APP or body fat scale APP installed on the terminal device 200. Figure 3 A schematic diagram of the human body composition measurement process, such as... Figure 3 As shown, after a user clicks on the body fat scale app, they will be redirected to the default location. Figure 3 The interface shown in (a) displays user information and the results of the previous body composition measurement. At the bottom of the interface is a menu bar: Home, Weigh On, and Trends. "Home" refers to… Figure 3 (a) shows the interface where the user clicks "Put on the scale" and then enters... Figure 3 (b) shows the interface where “Trend” can display the changes in a user’s weight, fat or muscle over a period of time using curves.

[0082] Figure 3 (b) The interface displays a thumbnail of the electronic scale and usage prompts, such as "Please step onto the scale barefoot." After the user steps onto the detection device 100, they click on the thumbnail of the electronic scale to trigger the measurement. The detection device 100 measures the human body impedance and sends it to the terminal device 200. The terminal device 200 processes the human body impedance to obtain the human body composition and then... Figure 3 (c) shows the interface displaying the body composition measurement results. Figure 3 As shown in (c), the measurement results of the body composition include body score, body age, current weight, body fat percentage, body water percentage, basal metabolic rate, protein, muscle mass, etc. Optionally, target weight and the difference between current weight and target weight are also displayed.

[0083] Optionally, in scenario two, after the detection device 100 measures the human body impedance, it can also process the human body impedance to obtain the human body composition and send the human body composition to the terminal device 200 for display.

[0084] In Scenario 1, since the display screen of the detection device 100 is small, it may not be possible to display the complete human body composition measurement results on one screen. In this case, a scrolling display method can be used to display the measurement results of each human body composition in sequence.

[0085] Optionally, the detector can use an impedance measurement method based on current and voltage. When using an impedance measurement method based on current and voltage, a current loop needs to be formed. Figure 1 In the detection device 100 shown, the electrodes of the two impedance measurement components of detectors 101 and 102 form a current loop. Current flows from detector 101 into the human body, passes through the human body, and flows out of the human body from detector 102. The electrodes of the two impedance measurement components of detectors 103 and 104 are used to measure voltage. The impedance measurement components calculate the human body impedance based on the current and the measured voltage.

[0086] In this embodiment, the dehumidifier may or may not come into contact with the human body surface during the dehumidification process. Whether the dehumidifier comes into contact with the human body during the dehumidification process is related to the structure of the dehumidifier or the dehumidification method. The dehumidifier can dehumidify through one or more methods such as heating, blowing air, or water absorption, and this embodiment does not limit this.

[0087] The support layer is used to support or install the impedance measurement component and the dehumidification component. The processor has the functions of controlling the various components inside the control detector, data processing, user information interaction, and data communication with the terminal equipment.

[0088] The processor can be implemented using one or more application-specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field-programmable gate arrays (FPGAs), controllers, microcontrollers, microprocessors, or other electronic components.

[0089] Optionally, the support layer may also include a memory, connecting leads, and a communication module. The connecting leads are used to connect with other components within the detector and to establish connections between detectors. The communication module is used to enable communication between the detection device 100 and the terminal device. The memory is used to store computer-executed instructions, and the processor executes the computer-executed instructions stored in the memory.

[0090] Optionally, after the detection device 100 is started, the dehumidification component can automatically trigger dehumidification of the contacted human body surface. After dehumidification is completed, the impedance measurement component begins to measure the human body impedance. The dehumidification component can dehumidify for a preset time, and dehumidification ends after the preset time is completed, assuming the human body surface is dry and human body impedance measurement can be performed. This dehumidification time can use the system default value or can be flexibly set by the user through the body composition measurement APP or body fat scale APP on the terminal device.

[0091] Figure 4 A schematic diagram of the interface for setting dehumidification time, such as... Figure 4 As shown, when a user opens the body fat scale app, the following steps are taken: Figure 4The settings interface shown in (a) includes the following settings: weight unit, family members, alarm reminder, target weight, help, and about. Users can set the weight unit to kilograms (kg) or pounds (lb) using the "weight unit" setting. Users can add multiple family members through the "family members" setting to measure and manage their body fat and body composition. Users can set the measurement time for body composition using the "alarm reminder" setting, and set their desired weight using the "target weight" setting. Users can also set the dehumidification time using the "dehumidification time" setting.

[0092] User click Figure 4 After setting the "Dehumidification Time" option in (a), the page will redirect to... Figure 4 (b) shows the dehumidification time setting page, which displays the current dehumidification time at the top of the page. After the user clicks on it, a settings pop-up appears, offering several selectable time options: 10 seconds, 30 seconds, 1 minute, 2 minutes, 3 minutes, or 5 minutes. The user clicks the select button next to each time option to complete the dehumidification time setting.

[0093] Optionally, after the detection device 100 is started, the dehumidification component can also dehumidify under other triggering conditions.

[0094] In an optional embodiment, at least one detector of the detection device 100 may further include a humidity measurement component electrically connected to the processor, the humidity measurement component being embedded in an impedance measurement component, and the upper surface of the humidity measurement component being in contact with a human body during measurement.

[0095] The humidity measurement component measures the humidity of the human body surface and sends the measured humidity value to the processor. The processor controls the dehumidification component to dehumidify when the humidity value measured by the humidity measurement component does not meet the measurement conditions required by the impedance measurement component. Optionally, the processor can also send the humidity value to the terminal device 200, which determines whether to perform dehumidification based on the humidity value. If dehumidification is required, the terminal device 200 can send a first indication message to the detection device 100, instructing the detection device 100 to perform dehumidification.

[0096] Optionally, in this application, a humidity measuring component can be provided on each detector, or only on some detectors. For example, if the detection device includes four detectors, a humidity measuring component can be provided on only one of the detectors, or on two of the detectors, or on all four detectors.

[0097] The measurement component needs to contact the human body surface to measure humidity. Since the upper surface of the impedance measurement component also needs to contact the human body during measurement, optionally, the humidity measurement component can be embedded in the impedance measurement component, with the upper surfaces of the humidity measurement component and the impedance measurement component located in the same plane. This ensures that the upper surfaces of both the humidity measurement component and the impedance measurement component can contact the human body surface while maintaining comfort during measurement.

[0098] The measurement conditions require dehumidification, for example, when the humidity value is greater than or equal to a preset humidity threshold. For instance, after the detection device 100 is activated, the humidity measurement component begins measuring the humidity of the human body surface. When the measured humidity value is greater than or equal to the preset humidity threshold, the processor determines to dehumidify the human body surface and controls the dehumidification component to begin dehumidification. When the measured humidity value is less than the preset humidity threshold, the processor determines not to dehumidify the human body surface. Optionally, the terminal device 200 can decide whether to dehumidify based on the same measurement conditions as the detection device 100. Of course, the terminal device can also decide whether to dehumidify based on other conditions; this embodiment does not limit this.

[0099] In one optional implementation, after the processor determines that the human body surface needs to be dehumidified (including determination by the detection device itself and determination by the terminal device), it can control the dehumidification component to dehumidify for a preset dehumidification time. Dehumidification ends after the dehumidification time is completed. The dehumidification time can be the system default value or can be flexibly set by the user on the terminal device and dynamically sent to the detection device.

[0100] In another alternative implementation, the processor can determine the dehumidification time based on the measured humidity value, or the terminal device can determine the dehumidification time based on the measured dehumidification value and send the dehumidification time to the detection device. The processor of the detection device controls the dehumidification component to dehumidify according to the dehumidification time, and the dehumidification ends after the dehumidification time is over.

[0101] In another optional implementation, the humidity measurement component continuously measures the humidity of the human body surface during the dehumidification process. When the measured humidity value meets the measurement condition requirements of the impedance measurement component, the dehumidification component is controlled to end the dehumidification operation. For example, dehumidification stops when the measured humidity value is less than a preset humidity threshold.

[0102] Optionally, the humidity measurement component includes one or more humidity sensors. The humidity sensors may be micro-electro-mechanical systems (MEMS) sensors.

[0103] When the detection device 100 includes a foot measuring device, the foot measuring device can be woken up (or started) by weight. When a measurement is needed, the user stands on the detection device 100. When the detection device 100 detects weight and the detected weight is greater than a set threshold, the detection device 100 starts, and the impedance measurement component, dehumidification component, and processor can begin operating. This embodiment is only illustrative; the detection device 100 can also use other start-up methods, such as voice wake-up, where the user can input a preset wake-up command via voice, or wake-up via a fixed button on the detection device 100. Optionally, the fixed button can be a physical button or a virtual button.

[0104] Optionally, the detection device 100 may also include a pressure sensor for measuring human body weight. When the detection device 100 is activated by weight, the pressure sensor can detect the user's weight. Upon detection of the user's weight, the detection device 100 starts and performs subsequent body composition detection.

[0105] When the detection device 100 includes multiple detectors, optionally, a pressure sensor can be set on each detector, and the pressure sensor is connected to the processor. Alternatively, pressure sensors can be set on only some detectors, for example, only on one of the detectors.

[0106] Optionally, the detection device 100 may also include a display screen 3, which is connected and communicates with the processor. The display screen 3 can be used to display the body composition measurement results, the user's weight, and some prompts. The size and position of the display screen 3 can be as follows: Figure 1 As shown, of course, the size and position of display screen 3 are not limited to... Figure 1 As shown.

[0107] Optionally, the detection device 100 may also include a microphone and / or a loudspeaker, which are connected and communicate with the processor. The microphone can be used to detect sound signals; for example, when the detection device 100 uses voice wake-up, the microphone collects the user's voice signal and sends it to the processor for processing. The processor recognizes the sound signal and decides whether to wake up the detection device 100. The loudspeaker is used to play sound signals; for example, it can play the results of the human body composition detection via voice, or it can play some prompts.

[0108] Optionally, when the measured humidity value is greater than or equal to a preset humidity threshold, the processor is also used to output a first prompt message. The first prompt message is used to prompt whether to perform dehumidification. When the processor receives a confirmation instruction for dehumidification input by the user based on the first prompt message, dehumidification is performed through the dehumidification component.

[0109] The processor can output the initial prompt message in the following ways:

[0110] Method 1: When the detection device 100 includes a display screen, the first prompt information is sent to the display screen for display. The user can select whether to perform dehumidification through virtual or physical buttons on the display screen, or the user can input a dehumidification command via voice. The detection device 100 can collect the user's voice signal through a microphone, and the processor recognizes the voice signal to obtain the dehumidification command. The dehumidification command is either a confirmation dehumidification command or a denial dehumidification command. The confirmation dehumidification command is used to instruct the detection device 100 to perform dehumidification, and the denial dehumidification command is used to instruct the detection device 100 not to perform dehumidification.

[0111] Method 2: When the detection device 100 includes a microphone and a loudspeaker, the first prompt information can be played through the loudspeaker. According to the first prompt information, the user can input the dehumidification command by voice. The microphone collects the sound signal input by the user, and the processor recognizes the sound signal to obtain the dehumidification command.

[0112] Method 3: The detection device 100 sends the first prompt information to the terminal device. The terminal device displays the first prompt information on the screen or plays the first prompt information through a loudspeaker. The user selects whether to dehumidify based on the first prompt information, and the terminal device sends the dehumidification command entered by the user to the detection device.

[0113] In one scenario, after a user finishes exercising, the detection device 100 is used to measure body composition. When the user steps on the detection device 100, the detection device 100 is activated, and its display screen is lit up. At this time, the first prompt message is displayed on the display screen of the detection device 100. Figure 5 This is a schematic diagram of the display interface of the testing equipment, such as... Figure 5 As shown, for example, the first prompt message is "Clean the moisture?". The user selects "Yes" or "No". When the user selects "Yes", the body composition detection device starts dehumidification. When the user selects "No", the body composition detection device ends the body composition measurement or directly measures the body impedance, skipping the dehumidification process.

[0114] When the display screen of the testing device 100 is a touch screen, the user can select "yes" or "no" by touch operation, or by voice input. When the display screen of the testing device 100 is not a touch screen, the testing device 100 is equipped with physical buttons, and the user can select "yes" or "no" by operating the physical buttons, or by voice input.

[0115] In another scenario, after the user finishes exercising, body composition is measured using the detection device 100 and the terminal device controlling the detection device 100, with reference to... Figure 3 As shown, after the user opens the body fat scale app and clicks the "Step on the scale" button, they can enter... Figure 3 (b) As shown in the interface, after the user steps onto the detection device 100, they can click on the thumbnail of the electronic scale to trigger the measurement and enter... Figure 6 The interface shown is as follows: Figure 6 As shown, the interface displays a first prompt message and selection controls. The first prompt message is, for example, "Clean moisture?". The selection controls include "Yes" and "No" buttons. The user selects "Yes" to begin dehumidification. After dehumidification is complete, body composition is measured, and the results are processed... Figure 3 The interface shown in (c) is displayed.

[0116] Understandable. Figure 5 and Figure 6 This is just an illustration; the initial prompt and selection controls can be represented in other ways.

[0117] When the detection device 100 receives a dehumidification denial command input by the user based on the first prompt information, optionally, the processor can also output a second prompt information to remind the user to dry their hands and feet before performing the test. For example, the second prompt information can be displayed on the display screen of the detection device 100, or on the display interface of a terminal device. An example of the second prompt information is: "To ensure accuracy, please dry your hands and feet before measuring again."

[0118] Optionally, after dehumidification is complete, a third prompt message is output to indicate the start of human body impedance measurement. For example, the third prompt message could be "Human body surface moisture cleaned, starting human body impedance measurement," to help the user understand the measurement progress and improve the user experience. For instance, after dehumidification is complete, the detection device 100 displays this third prompt message "Human body surface moisture cleaned, starting human body impedance measurement" on the display screen. This third prompt message continues to be displayed during the measurement process, and disappears after the measurement is completed. The content displayed on the screen then changes to the human body composition measurement results. Optionally, the third prompt message can also disappear after a preset time, such as after 1 or 2 seconds. At this time, the display screen may not display any content, or it may display a "Measuring in progress" notification message, which can be displayed in text form, or in an animated or other form.

[0119] Alternatively, after dehumidification is complete, the detection device 100 notifies the terminal device that dehumidification is finished. The terminal device displays a third prompt message on its display interface while simultaneously performing body composition measurement. During the measurement process, the terminal device can continuously display the third prompt message. After the measurement is completed, the third prompt message will no longer be displayed, and the page will redirect to the body composition measurement result display interface. Optionally, the third prompt message can also disappear after a preset time. At this time, the terminal device's interface may not display any content, or it may display a "Measuring" notification message, which can be displayed in text form, or in an animation or other form.

[0120] Figure 1 The detection device 100 shown includes four detectors. In other embodiments of this application, the detection device may include more or fewer detectors. For example, the detection device 100 may include one detector, two detectors, six detectors, eight detectors, etc. Furthermore, the shape of the detectors is not limited to... Figure 1 The circle shown can also be other shapes. For example, the detector can also be elliptical, square, rectangular or other irregular shapes. This embodiment does not limit this.

[0121] It should be clarified that, in the embodiments of this application, the detection device 100 may include a processor (or support layer), multiple detectors may share a processor, or each detector may have its own processor. The processors of each detector may communicate with each other, and one of the processors may be designated to interact with the terminal device or other devices.

[0122] Figure 7 This is another schematic diagram of the external structure of a human body composition detection device, such as... Figure 7 As shown, the testing equipment is similar to... Figure 1 Compared to the detection device shown, this detection device includes two detectors: detector 201 and detector 202. The shapes of detectors 201 and 202 are approximately elliptical, although the shapes of detectors 201 and 202 are not limited to... Figure 7 The shape shown. Figure 2 The area of ​​the detector shown is greater than Figure 1 The area of ​​the detector shown is large enough to cover the human foot, achieving comprehensive dehumidification of the human foot.

[0123] In use Figure 7When the detection device 100 is used for measurement, the human body has both feet on the detectors; exemplarily, the left foot is on detectors 201 and 202. When using an impedance measurement method based on current and voltage, current flows from detector 201 into the human body, passes through the body, and flows out of the body from detector 202. The electrodes of the two impedance measurement components of detectors 201 and 202 are used to measure voltage; in this method, the voltage loop multiplexes the current loop. The impedance measurement components calculate the human body impedance based on the current and the measured voltage.

[0124] Figure 8 This is another schematic diagram of the external structure of a human body composition detection device, such as... Figure 8 As shown, the testing equipment is similar to... Figure 1 Compared to the detection device shown, this detection device includes a detector 301, which is circular in shape. Of course, the shape of the detector 301 is not limited to... Figure 3 The shape shown can also be an ellipse or a square, and the area of ​​detector 301 covers the human foot.

[0125] Figure 1 and Figure 8 The human body composition detection device shown can employ impedance measurement based on current and voltage. This method requires the formation of a current loop and a voltage loop through the human body. Of course, other methods can also be used for impedance measurement that do not require the formation of current and voltage loops. Figure 4 The human body composition detection device shown has only one detector, which cannot form a current loop and a voltage loop. Therefore, an impedance measurement method based on non-current and voltage can be used.

[0126] Figure 1 , Figure 7 and Figure 8 The detection device 100 shown is a foot detection device. When the detection device is a hand detection device or includes a hand detection device, the hand detection device can be... Figure 9 The structure shown is for reference. Figure 9 As shown, the hand detection device can be cylindrical. During measurement, the user's hand can grip the hand detection device, triggering the device to start measurement. The hand detection device includes a housing 2 and four detectors: detector 401, detector 402, detector 403, and detector 404.

[0127] This embodiment does not limit the shape of the hand detection device. The hand detection device includes a detector and a housing. The hand detection device may include one or more detectors. The structure of the detector of the hand detection device is the same as the structure of the detector of the foot detection device described above, and will not be described in detail here.

[0128] Figure 10This is a schematic diagram of another external structure of a hand detection device, such as... Figure 10 As shown, the hand detection device includes a housing 2 and two detectors: detector 501 and detector 502, the outer surface of each detector can be wrapped around the cylindrical hand detection device.

[0129] Figure 11 This is another schematic diagram of the external structure of a hand detection device, such as... Figure 11 As shown, the hand detection device includes a housing 2 and a detector 601. The outer surface of the detector 601 can be wrapped around the cylindrical hand detection device.

[0130] Optionally, the hand detection device may also include one or more of the following components: a display screen, a microphone, or a loudspeaker. The hand detection device can be woken up using the aforementioned weight-based wake-up, voice-based wake-up, or button-based wake-up methods, which will not be elaborated further here.

[0131] When the testing equipment includes both foot and hand detection devices, users can simultaneously use both devices for measurements. The hand and foot detection devices can connect and communicate with each other via wired or wireless means. For wired connections, the cable can connect to both devices via a USB interface. Wireless connections can use Bluetooth or other short-range communication technologies. During use, the user places their foot on the foot detection device while simultaneously holding the hand detection device, thus measuring human body impedance.

[0132] The hand and foot detection devices can communicate via wired or wireless means to exchange measurement data. Typically, the foot detection device can detect body weight and body impedance, while the hand detection device can only detect body impedance. The hand detection device can transmit the detected body impedance to the foot detection device via wired or wireless means. The foot detection device processes the body weight, its own measured body impedance, and the body impedance measured by the hand detection device to obtain body composition.

[0133] Optionally, the foot detection device can also send the body weight, the body impedance measured by itself, and the body impedance measured by the hand detection device to a mobile phone or other electronic device connected to the foot detection device. Taking the mobile phone as an example, after receiving the body weight, the body impedance measured by the foot detection device, and the body impedance measured by the hand detection device, the mobile phone processes the body weight, the body impedance measured by the foot detection device, and the body impedance measured by the hand detection device to obtain the body composition.

[0134] The human body composition detection device provided in this application includes a dehumidification component. Before the impedance measurement component performs human body impedance measurement, the dehumidification component first dehumidifies the human body surface that the impedance measurement component contacts. After the moisture on the human body surface is removed, the human body impedance measurement component measures the human body impedance, thereby improving the accuracy of human body impedance measurement and thus improving the accuracy of human body composition detection through human body impedance.

[0135] Embodiment 1 of this application provides a human body composition detection device based on dehumidification by heating, wherein the dehumidification component adopts an electric heating element. Figure 12 This is an exploded schematic diagram of the detector in a body composition detection device that uses heating for dehumidification. Figure 13 for Figure 12 The diagram shows the appearance of the detector in the human body composition detection device. (Reference) Figure 12 and Figure 13 The detector includes an impedance measurement component 11, an electric heating element 12, a support layer 13, a humidity measurement component 14, and a pressure sensor 15. In this embodiment, the outer casing 2 of the detection device 100 includes an upper casing 21 and a lower casing 22.

[0136] The impedance measurement component 11, the upper shell 21, the electric heating element 12, and the support layer 13 are stacked from top to bottom. The impedance measurement component 11, the upper shell 21, and the electric heating element 12 are respectively provided with through holes. The through holes on the impedance measurement component 11, the upper shell 21, and the electric heating element 12 are the same size and their centers are aligned. The humidity measurement component 14 is installed in the through hole. The lower end of the humidity measurement component 14 is electrically connected to the support layer 13. The upper end of the humidity measurement component 14 passes through the electric heating element 12, the upper shell 21, and the impedance measurement component 11 from bottom to top.

[0137] Optionally, the through hole is located at the center of the impedance measuring component 11 and the electric heating element 12. It is understood that the through hole can also be located at other positions of the impedance measuring component 11 and the electric heating element 12, and this embodiment does not limit this.

[0138] When the electric heating element 12 is powered on, the heat is conducted to the human body surface after passing through the upper shell 21 and the impedance measurement component 11, thereby achieving dehumidification of the human body surface.

[0139] When measuring human body composition, the upper surfaces of both the humidity measuring component 14 and the impedance measuring component 11 need to be in contact with the human body surface. Optionally, in this embodiment, the upper surfaces of the humidity measuring component 14 and the impedance measuring component 11 are located in the same plane, and the upper surface of the impedance measuring component 11 is parallel to or higher than the upper surface of the upper shell 21, thereby ensuring that the human body surface can contact the upper surfaces of both the humidity measuring component 14 and the impedance measuring component 11 when measuring human body composition. Optionally, the upper surface of the humidity measuring component 14 is slightly higher than the upper surface of the impedance measuring component 11.

[0140] The support layer 13 includes a processor, connecting leads, etc. (not shown in the figure). In this embodiment, the support layer 13 also has a supporting and mounting function, such as... Figure 7 As shown, the upper surface of the support layer 13 has a circular groove, in which the circular electric heating element 12 can be accommodated, thereby fixing the electric heating element 12. The electrodes of the electric heating element 12 are connected to the support layer 13 through leads.

[0141] Optionally, the pressure sensor 15 is mounted below the support layer 13. For example, the lower surface of the pressure sensor 15 has a central protrusion that passes through a hole in the lower housing 22. Since the pressure sensor 15 is compressed during measurement, its bottom needs support while its top remains unobstructed when used for measurement. Alternatively, when the detection device is not used for measurement, the bottom of the pressure sensor 15 may be in contact with the ground or not; when used for measurement, the bottom of the pressure sensor 15 contacts the ground due to compression, thus enabling the pressure sensor 15 to measure the weight of the human body.

[0142] Optionally, the impedance measuring component 11 and the electric heating element 12 are circular. Optionally, the impedance measuring component 11 and the electric heating element 12 are the same size. It is understood that the impedance measuring component 11 and the electric heating element 12 can also take other shapes than circular, and their sizes can also be different.

[0143] Optionally, the impedance measurement component 11 is an impedance measurement electrode, which is formed by coating the upper surface of the upper housing 21.

[0144] Optionally, the impedance measurement component 11 is an independent component, and the impedance measurement component 11 is disposed in the groove of the upper shell 21.

[0145] The human body composition detection device of this embodiment includes an electric heating element 12 and a humidity measurement component 14. After the detection device is activated, the humidity measurement component 14 begins to measure the humidity of the human body surface. When the measured humidity value does not meet the measurement requirements, the electric heating element 12 begins to dehumidify the human body surface. When the measured humidity value meets the measurement requirements, the electric heating element 12 ends the dehumidification operation, and the human body impedance measurement component 11 measures the human body impedance. Before measuring the human body impedance, the electric heating element 12 dehumidifies the human body surface. Only after the moisture on the human body surface is removed is the human body impedance measurement performed, thereby improving the accuracy of the human body impedance measurement and thus improving the accuracy of human body composition detection through human body impedance.

[0146] Embodiment 2 of this application provides a human body composition detection device based on dehumidification by blowing air, wherein the dehumidification component adopts a fan. Figure 14 This is an exploded schematic diagram of the detector in a body composition detection device that uses airflow for dehumidification. Figure 15 for Figure 14 The diagram shows the appearance of the detector in the human body composition detection device. (Reference) Figure 14 and Figure 15 The detector 1 includes an impedance measurement component 11, a fan 16, a support layer 13, a humidity measurement component 14, and a pressure sensor 15. In this embodiment, the outer casing 2 of the detection device 100 includes an upper casing 21 and a lower casing 22.

[0147] The impedance measurement component 11, upper shell 21, fan 16, and support layer 13 are stacked from top to bottom. Through holes are provided on the impedance measurement component 11 and upper shell 21. The through holes on the impedance measurement component 11 and upper shell 21 are the same size and their centers are aligned. The humidity measurement component 14 is installed in the through hole. The electrical connection wires of the humidity measurement component 14 and the impedance measurement component 11 are connected to the processor in the support layer 13 through the wire lead-out slot 161 on the upper surface of the fan 16. The lower end of the humidity measurement component 14 contacts the fan 16, and the upper end of the humidity measurement component 14 passes through the upper shell 21 and the impedance measurement component 11 from bottom to top. Multiple ventilation holes are provided at corresponding positions on the impedance measurement component 11 and upper shell 21. The air blown by the fan 16 is directed towards the human body surface through these ventilation holes, achieving dehumidification of the human body surface.

[0148] In an optional embodiment, through holes are provided on the impedance measurement component 11, the upper shell 21 and the fan 16 respectively. The humidity measurement component 14 is installed in the through holes. The lower end of the humidity measurement component 14 is electrically connected to the support layer 13. The upper end of the humidity measurement component 14 passes through the fan 16, the upper shell 21 and the impedance measurement component 11 from bottom to top.

[0149] Optionally, the through hole is located at the center of the impedance measurement component 11 and the fan 16. It is understood that the through hole can also be located at other positions of the impedance measurement component 11 and the fan 16, and this embodiment does not limit this.

[0150] When measuring human body composition, the upper surfaces of both the humidity measuring component 14 and the impedance measuring component 11 need to be in contact with the human body surface. Therefore, in this embodiment, the upper surfaces of the humidity measuring component 14 and the impedance measuring component 11 are located in the same plane, and the upper surface of the impedance measuring component 11 is parallel to or higher than the upper surface of the upper shell 21. This ensures that the human body surface can contact the upper surfaces of both the humidity measuring component 14 and the impedance measuring component 11 when measuring human body composition. Optionally, the upper surface of the humidity measuring component 14 is slightly higher than the upper surface of the impedance measuring component 11.

[0151] The support layer 13 includes a processor, connecting leads, etc. (not shown in the figure). In this embodiment, the support layer 13 also has a supporting and mounting function, such as... Figure 9 As shown, the upper surface of the support layer 13 has a circular groove, in which the circular fan 16 can be accommodated, thereby fixing the fan 16. The fan 16 is connected to the support layer 13 through a lead wire.

[0152] Optionally, the pressure sensor 15 is mounted below the support layer 13. For example, the pressure sensor 15 has a central protrusion on its lower surface that passes through a hole in the lower housing 22. The mounting method of the pressure sensor 15 is described in the relevant description of Embodiment 1, and will not be repeated here.

[0153] Optionally, the impedance measuring component 11 has a circular structure. It is understood that the impedance measuring component may also take other shapes than circular.

[0154] Optionally, the impedance measurement component 11 is an impedance measurement electrode, which is formed by coating the upper surface of the upper housing 21.

[0155] Optionally, the impedance measurement component 11 is an independent component, and the impedance measurement component 11 is disposed in the groove of the upper shell 21.

[0156] The human body composition detection device of this embodiment includes a fan 16 and a humidity measurement component 14. After the detection device is activated, the humidity measurement component 14 begins to measure the humidity of the human body surface. When the measured humidity value does not meet the measurement requirements, the fan 16 begins to dehumidify the human body surface. During the dehumidification process of the fan 16, the humidity measurement component 14 continues to measure the humidity of the human body surface. When the measured humidity value meets the measurement requirements, the fan 16 stops dehumidifying the human body surface, and the human body impedance measurement component 11 begins to measure the human body impedance. Before measuring the human body impedance, the fan 16 dehumidifies the human body surface. Only after the moisture on the human body surface is removed is the human body impedance measurement performed, thereby improving the accuracy of the human body impedance measurement and thus improving the accuracy of human body composition detection through human body impedance.

[0157] Embodiment 3 of this application provides a human body composition detection device based on water absorption dehumidification, wherein the dehumidification component adopts a drying coil. Figure 16 This is an exploded schematic diagram of the detector in a body composition detection device that uses water absorption for dehumidification. Figure 17 for Figure 16 A side view of the detector of the human body composition detection device shown, with reference to... Figure 16 and Figure 17 The detector 1 includes an impedance measurement component 11, a drying ring 17, a support layer 13, a humidity measurement component 14, and a pressure sensor 15. In this embodiment, the outer casing 2 of the detection device 100 includes an upper casing 21 and a lower casing 22.

[0158] The impedance measuring component 11 has an arc-shaped protrusion structure, and the drying ring 17 is arranged around the impedance measuring component 11. The upper surface of the drying ring 17 is lower than or parallel to the outer edge of the impedance measuring component 11, thereby forming a slope so that water droplets on the human body surface can roll from the top of the impedance measuring component 11 to the drying ring 17, and the drying ring 17 absorbs moisture.

[0159] In this embodiment, the impedance measurement component 11, the upper shell 21, and the support layer 13 are stacked from top to bottom. The impedance measurement component 11 and the upper shell 21 are respectively provided with through holes. The through holes on the impedance measurement component 11 and the upper shell 21 are the same size and their centers are aligned. The humidity measurement component 14 is installed in the through hole. The lower end of the humidity measurement component 14 is electrically connected to the support layer 13. The upper end of the humidity measurement component 14 passes through the upper shell 21 and the impedance measurement component 11 from bottom to top.

[0160] Optionally, the connection position between the upper surface of the drying ring 11 and the impedance measurement component 11 can be smoothly transitioned.

[0161] Optionally, the through hole is located at the center of the impedance measurement component 11. It is understood that the through hole can also be located at other locations of the impedance measurement component 11, and this embodiment does not limit this.

[0162] The impedance measurement component 11 is made of superhydrophobic conductive material and has an arc-shaped protrusion structure. When the user performs the measurement, the water droplets on the human body surface will be affected by gravity, with the direction of gravity being as follows: Figure 12 As shown, water droplets roll off the top of the protrusion of the impedance measurement component 11 in all directions onto the drying ring 17. The drying ring 17 is made of superhydrophilic or superabsorbent material, which can quickly absorb the rolling water droplets, thereby achieving dehumidification of the human body surface.

[0163] When measuring human body composition, the upper surfaces of both the humidity measuring component 14 and the impedance measuring component 11 need to be in contact with the human body surface. Therefore, in this embodiment, the upper surfaces of the humidity measuring component 14 and the impedance measuring component 11 are located in the same plane, and the upper surface of the impedance measuring component 11 is parallel to or higher than the upper surface of the upper shell 21. This ensures that the human body surface can contact the upper surfaces of both the humidity measuring component 14 and the impedance measuring component 11 when measuring human body composition. Optionally, the upper surface of the humidity measuring component 14 is slightly higher than the upper surface of the impedance measuring component 11.

[0164] The support layer 13 includes a processor, connecting leads, etc. (not shown in the figure).

[0165] Optionally, the pressure sensor 15 is mounted below the support layer 13. For example, the pressure sensor 15 has a central protrusion on its lower surface that passes through a hole in the lower housing 22. The mounting method of the pressure sensor 15 is described in the relevant description of Embodiment 1, and will not be repeated here.

[0166] Optionally, the impedance measuring component 11 has a circular structure, and the drying ring 17 has the same shape as the impedance measuring component 11, surrounding the impedance measuring component 11. It is understood that the impedance measuring component 11 and the drying ring 17 can also adopt other shapes besides circular.

[0167] In an optional embodiment, there can be multiple pairs of drying rings 17 and impedance measurement components 11, which are arranged in multiple layers with the innermost layer being the impedance measurement components 11 and the outermost layer being the drying rings 17. Of course, the height of the multiple drying rings 17 and impedance measurement components 11 decreases from the inside to the outside, thereby ensuring that water droplets roll down from a height to the drying rings.

[0168] The human body composition detection device of this embodiment includes a drying ring 17 and a humidity measurement component 14. After the detection device is activated, the drying ring 17 dehumidifies the human body surface, and the humidity measurement component 14 begins to measure the humidity of the human body surface. When the measured humidity value does not meet the measurement requirements, the impedance measurement component 11 does not perform impedance measurement. During the dehumidification process, the humidity measurement component 14 continues to measure the humidity of the human body surface. When the measured humidity value meets the measurement requirements, the impedance measurement component 11 begins to perform impedance measurement. By dehumidifying the human body surface through the drying ring 17, and performing human body impedance measurement only after the moisture on the human body surface has been removed, the accuracy of human body impedance measurement is improved, thereby improving the accuracy of human body composition detection through human body impedance.

[0169] The human body composition detection devices provided in Embodiments 1 to 3 describe the support layer (or processor) as part of the detector. It can be understood that the support layer may not belong to a single detector, but is a component shared by multiple detectors.

[0170] Figure 18 This is a flowchart of the human body composition detection method provided in Embodiment 4 of this application. The method provided in this embodiment can be executed by the human body composition detection device described in any of the above embodiments, such as... Figure 18 As shown, the method provided in this embodiment includes the following steps:

[0171] S1301, The dehumidification component dehumidifies the human body surface it comes into contact with.

[0172] After the body composition detection device is activated, the dehumidification unit dehumidifies. The body composition detection device can be activated by one or more of the following methods: weight activation, voice activation, or button activation.

[0173] Weight-based wake-up refers to the activation of a body composition detection device when a person comes into contact with it and the device detects the user's weight, which exceeds a set threshold. For example, the foot detection device is activated when the user stands on it, and the hand detection device is activated when the user holds it.

[0174] Voice wake-up refers to the user inputting a preset wake-up command via voice. After the body composition detection device recognizes the preset wake-up command, it wakes up the device.

[0175] Button wake-up refers to the user waking up the body composition detection device by pressing or touching a fixed button on the device. Optionally, the fixed button can be a physical button or a virtual button.

[0176] In one optional implementation, after the human body composition detection device is activated, the dehumidification component immediately begins dehumidifying the surface of the human body it is in contact with. After dehumidification is complete, human body impedance measurement begins. The dehumidification component can dehumidify for a preset time, ending dehumidification after the preset time, assuming the human body surface is dry, and then human body impedance measurement can be performed. This dehumidification time can use a system default value or can be flexibly set by the user. For example, the dehumidification time can be 1 minute, 2 minutes, 3 minutes, or 5 minutes, etc.

[0177] In another alternative implementation, the dehumidifier initiates dehumidification under certain triggering conditions. For example, before dehumidifying the surface of the human body, the dehumidifier measures the humidity of the surface and determines whether the measured humidity value meets the measurement requirements. If the humidity value does not meet the requirements, the dehumidifier dehumidifies the surface. If the humidity value meets the requirements, dehumidification is not necessary; instead, the body impedance is measured directly.

[0178] Alternatively, the body composition detection device sends the measured humidity value of the human body surface to the terminal device, which then determines whether the humidity value of the human body surface meets the measurement requirements. If the humidity value of the human body surface does not meet the measurement requirements, the terminal device instructs the body composition detection device to dehumidify. If the humidity value of the human body surface meets the measurement requirements, the terminal device instructs the body composition detection device to start measuring the human body impedance.

[0179] Optionally, the terminal device may also send a dehumidification time to the human body composition detection device. After the dehumidification time is completed, the human body composition detection device begins measuring human body impedance. Alternatively, the terminal device may not send a dehumidification time to the human body composition detection device. Instead, after the dehumidification time is completed or when the humidity value on the human body surface meets the measurement requirements, the terminal device may send a second indication message to the human body composition detection device. This second indication message indicates that dehumidification should be stopped and that human body impedance measurement should begin.

[0180] Optionally, the measurement condition requires dehumidification when the humidity value is greater than or equal to a preset humidity threshold. For example, after the human body composition detection device is activated, it begins measuring the humidity of the human body surface. When the measured humidity value is greater than or equal to the preset humidity threshold, the dehumidification component begins dehumidifying the human body surface. When the measured humidity value is less than the preset humidity threshold, the human body impedance is measured.

[0181] When the measured humidity value is greater than or equal to a preset humidity threshold, the dehumidifier can dehumidify for a preset time, ending the dehumidification operation after the preset time. Alternatively, the body composition detection device determines the dehumidification time based on the measured humidity value and controls the dehumidifier to dehumidify for that time. Alternatively, during the dehumidification process, the body composition detection device continuously measures the humidity of the human body surface; when the measured humidity value meets the measurement conditions of the impedance measurement component, it controls the dehumidifier to end the dehumidification operation.

[0182] Optionally, when the humidity level on the human body surface does not meet the measurement requirements, a first prompt message is output to indicate whether dehumidification should be performed. Based on the first prompt message, the user inputs a confirmation or denial command for dehumidification. Upon receiving a confirmation command from the user based on the first prompt message, the dehumidification component dehumidifies the human body surface. For example, the first prompt message might be "Clean moisture?", and the user selects "Yes" or "No". When the user selects "Yes", the human body composition detection device begins dehumidification; when the user selects "No", the device does not dehumidify and can directly measure human body impedance.

[0183] Optionally, when a user's denial dehumidification command is received based on the first prompt, a second prompt is output. The second prompt prompts the user to dry their hands and feet before performing the test. For example, the second prompt might be: "To ensure accuracy, please dry your hands and feet before measuring again."

[0184] Optionally, after outputting the second prompt message, the human body composition detection device can either end the measurement process or continue to measure human body impedance and obtain human body composition based on the human body impedance. According to the second prompt message mentioned above, the user can know that the measured human body composition is inaccurate and is for reference only.

[0185] In another implementation, before the dehumidification component dehumidifies the human body surface it contacts, it receives a first instruction message sent by a terminal device. The first instruction message is used to instruct dehumidification to be performed before measuring human body impedance. The dehumidification component dehumidifies the human body surface according to the first instruction message. The terminal device is used to control the human body composition detection device.

[0186] Optionally, the body composition detection device also receives the dehumidification time sent by the terminal device, and confirms that dehumidification is complete when the dehumidification time is reached. The first indication information and the dehumidification time can be sent by the terminal device to the body composition detection device via a single message or two messages.

[0187] Optionally, the dehumidifier may dehumidify using one or more of the following methods: heating, air blowing, or water absorption. When dehumidifying by heating, the dehumidifier may be an electric heating element that heats up when powered on. When dehumidifying by air blowing, the dehumidifier may be a fan that accelerates air circulation to dehumidify. When dehumidifying by water absorption, the dehumidifier may be a highly absorbent drying coil that absorbs moisture upon contact with the human body surface.

[0188] S1302. After dehumidification is completed, measure human body impedance.

[0189] After the human body surface is dehumidified and dried, human body impedance can be measured, and the measured human body impedance is accurate.

[0190] Optionally, after dehumidification is complete, the human body composition detection device can also output a third prompt message to indicate the start of human body impedance measurement. For example, the third prompt message could be "Start measuring human body impedance," "Clean hands or feet of moisture," or "Clean hands or feet of moisture, start measuring human body impedance."

[0191] In other possible embodiments of this application, after dehumidification is completed, no third prompt message is output, and the human body composition detection device starts measuring human body impedance by default.

[0192] S1303. Process the measured human body impedance values ​​to obtain human body composition.

[0193] The conversion from human body impedance to human body composition can be achieved using existing methods, and the embodiments of this application do not limit this.

[0194] S1304, Output human body composition information.

[0195] The body composition detection device can output body composition in one or more of the following ways: (1) when the body composition detection device includes a display screen, the body composition is sent to the display screen for display. (2) the body composition is played out by voice. (3) the body composition is sent to a terminal device, and the body composition is displayed and / or played out by voice on the terminal device.

[0196] Optionally, in other embodiments of this application, after measuring human body impedance, the human body composition detection device does not process the human body impedance, but instead sends the human body impedance to a terminal device, which processes the human body impedance to obtain human body composition.

[0197] In this embodiment, the human body surface is dehumidified before the human body impedance measurement is performed. After the moisture on the human body surface is removed, the human body impedance is measured, thereby improving the accuracy of the human body impedance measurement and thus improving the accuracy of human body composition detection through human body impedance.

[0198] Based on the method of Example 4, Figure 19 This is a flowchart of the human body composition detection method provided in Embodiment 5 of this application. The method provided in this embodiment can be executed by the human body composition detection device described in any of the above embodiments, such as...

[0200] S1402. Measure the humidity of the human body surface (feet or hands).

[0201] S1403. Determine whether the humidity value of the human body surface meets the measurement requirements.

[0202] If the humidity value of the human body surface meets the measurement requirements, proceed to step S1408; if the humidity value of the human body surface does not meet the measurement requirements, proceed to step S1404.

[0203] S1404. Output the first prompt message to ask the user whether to perform dehumidification.

[0204] When the user selects dehumidification, step S1405 is executed, followed by step S1407. When the user selects not to dehumidify, step S1406 is executed, followed by the end.

[0205] S1405. The dehumidification component dehumidifies the human body surface and continuously measures the humidity of the human body surface.

[0206] S1406, Output the second prompt message.

[0207] The second prompt message is to remind the user to dry the product before proceeding with the test.

[0208] S1407. When the humidity value of the human body surface meets the measurement requirements, output the third prompt message to indicate that the measurement of human body impedance has started.

[0209] S1408. Measure human body impedance and determine human body composition based on human body impedance.

[0210] S1409. Send human body composition information to the terminal device.

[0211] S1410, End.

[0212] The specific implementation of this embodiment can be found in the relevant description of Embodiment 4, and will not be repeated here.

[0213] Figure 20 This is a flowchart of the human body composition detection method provided in Embodiment 5 of this application. The method provided in this embodiment can be executed by a terminal device, such as... Figure 20 As shown, the method provided in this embodiment includes the following steps:

[0214] S1501, The terminal device sends a first instruction message to the human body composition detection device, the first instruction message being used to instruct the human body composition detection device to dehumidify before measuring human body impedance.

[0215] Optionally, before sending the first instruction information to the human body composition detection device, the terminal device displays a first prompt information. The first prompt information is used to indicate whether dehumidification should be performed. The display format of the first prompt information can refer to... Figure 6 As shown. The user inputs a confirmation dehumidification command or a denial dehumidification command based on the first prompt information. When the terminal device receives the confirmation dehumidification command input by the user based on the first prompt information, it sends a first instruction message to the human body composition detection device. When the terminal device receives the denial dehumidification command input by the user based on the first prompt information, it displays a second prompt information, which is used to remind the user to dry off the moisture before proceeding with the detection.

[0216] In one implementation, the terminal device displays a default first prompt message after the user triggers the measurement. In another implementation, before outputting the first prompt message, the terminal device receives the humidity value of the human body surface sent by the detection device. If the humidity value of the human body surface does not meet the measurement requirements, the terminal device outputs the first prompt message. After the detection device is activated, it begins to measure the humidity value of the human body surface and sends the measured humidity value to the terminal device.

[0217] During the dehumidification process of this detection device, the device can continuously or periodically detect the humidity value of the human body surface and send the humidity value of the human body surface to the terminal device. When the terminal device determines that the humidity value of the human body surface meets the measurement requirements, the terminal device sends a second indication message to the detection device to indicate that dehumidification should be stopped and to start measuring the human body impedance.

[0218] Optionally, during the dehumidification process, the detection device does not detect the humidity level on the human body surface. The device ends dehumidification after a preset dehumidification time and measures the human body impedance. Alternatively, the dehumidification time is sent to the detection device by the terminal device. Or, the terminal device sends a second instruction to the detection device based on user instructions or a preset dehumidification time.

[0219] S1502. The terminal device receives the human body impedance sent by the detection device.

[0220] After dehumidifying according to the first instruction information, the detection device measures the human body impedance and sends the measured human body impedance to the terminal device.

[0221] Optionally, before starting to measure human body impedance after the terminal device has completed dehumidification, the terminal device may display a third prompt message to indicate that the measurement of human body impedance has begun.

[0222] S1503. The terminal equipment processes the measured human body impedance values ​​to obtain human body composition.

[0223] S1504, The terminal device displays human body composition.
