[0019] In order to illustrate the technical solutions described in the present application, the following will be described through specific embodiments, and only the parts related to the embodiments of the present application are shown.

[0020] The present application provides a method for perceiving health based on a fingertip wearable spectral sensor, which is applied to a fingertip wearable spectral sensing glove. As Figures 1 to 4 , as shown in FIG. 7, the fingertip wearable spectral sensing glove 1 includes a housing 11, a spectral chip 12, and a main control module 13 disposed in the housing 11. The spectral chip 12 is electrically connected to the main control module 13; The housing 11 forms an adjustable-size light-shielding cavity 110 for sleeving the user's finger; The spectral chip 12 is located at the pulp position of the housing 11. The spectral chip 12 includes a broad-spectrum dot matrix light emission module from ultraviolet light to near-infrared light and a light signal receiving module for different reflected light wavelengths. Both the broad-spectrum dot matrix light emission module and the light signal receiving module are connected to the main control module 13; The broad-spectrum dot matrix light emission module is configured to emit one or more light signals from ultraviolet light to near-infrared light to the arterial blood vessel projection area of the user according to the control signal of the main control module 13; The light signal receiving module is configured to receive the light signal reflected by the arterial blood vessel projection area of the user; The main control module 13 is configured to obtain physiological health indicators according to the emitted light signal and the received light signal.

[0021] When the user uses the fingertip wearable spectral sensing glove 1 to test physiological health indicators, the finger is placed into the light-shielding cavity 110. Moreover, since the internal size of the light-shielding cavity 110 is adjustable, it can adapt to different sizes of the user's fingers. After the user wears it, the spectral chip 12 is located at the position of the user's finger pulp. The user places the finger wearing the fingertip wearable spectral sensing glove 1 on any arterial blood vessel projection area, presses the power button of the fingertip wearable spectral sensing glove 1, and the spectral chip 12 collects the characteristic spectral data corresponding to the user's arterial blood vessel projection area, thereby realizing the detection of the user's physiological health indicators.

[0022] In some embodiments, the housing 11 includes a front shell 111 and a rear shell 112. The front shell 111 and the rear shell 112 are detachably connected by a snap structure or a magnetic attraction structure, and are pivotally connected after being connected. The front shell 111 has a receiving groove, and the rear shell 112 has a hollow channel. The receiving groove is communicated with the hollow channel to form a light-shielding cavity 110 with one end being a closed structure and the other end being an open structure.

[0023] Since the front shell 111 and the rear shell 112 are in a pivotally connected relationship after being connected and can move relative to each other, the user's finger can bend and is more flexible.

[0024] In some embodiments, the inner diameter of the receiving groove is smaller than the inner diameter of the hollow channel.

[0025] The inner diameter of the receiving groove of the front shell 111 is smaller than the inner diameter of the hollow channel of the rear shell 112, which adapts to the shape of the human finger and conforms to ergonomics.

[0026] In some embodiments, the front shell 111 includes an upper cover 113 and a base 114. The upper cover 113 and the base 114 are fixedly connected to form a receiving groove, and a collection window is opened at the bottom of the base 114, and the spectral chip 12 is exposed at the collection window.

[0027] The collection window corresponds to the finger pulp of the finger, that is, the spectral chip 12 is arranged at the finger pulp position of the base 114, which is convenient for the user to press the finger to any arterial blood vessel projection area of the user after wearing the fingertip wearable spectral sensing glove 1.

[0028] For example, when the user wears the fingertip wearable spectral sensing glove 1 on the right thumb, since the spectral chip 12 is arranged at the finger pulp position, the user can align the finger pulp of the thumb with the base of the index finger of his own left hand. There is an arterial blood vessel projection area at the base of the finger, and it can also be aligned with the arterial blood vessel projection area of another user to perform physiological health monitoring on people other than those wearing the fingertip wearable spectral sensing glove 1.

[0029] As Figure 4 shown, the user wears the fingertip wearable spectral sensing glove 1 on the right thumb.

[0030] It is understandable that the fingertip wearable spectral sensing glove 1 can also be worn on other fingers, and the internal size of the light-shielding cavity 110 can be adjusted to fit the sizes of different fingers, which is not limited herein.

[0031] In some embodiments, a base 115 is fixed inside the base 114 for fixing the spectral chip 12; a buffer cushion layer is provided between the base 115 and the base 114 to reduce the vibration of the spectral chip 12 from the outside.

[0032] In some embodiments, a main board 14 is provided inside the rear shell 112. The main control module 13 is located on the upper surface of the main board 14. A power module 15 is provided on the lower surface of the main board 14. The power module 15 is electrically connected to the main control module 13, and the main control module 13 is electrically connected to the spectral chip 12 through a flexible cable.

[0033] The power module 15 supplies power to the main control module 13 and the spectral chip 12 to ensure the normal operation of the fingertip wearable spectral sensing glove 1.

[0034] In some embodiments, a switch button 16, an indicator light, and a light guide column are provided on the upper surface of the main board 14. The switch button 16 exposes the surface of the cover plate 1121 of the rear shell 112. The light guide column is sleeved on the indicator light. Both the switch button 16 and the indicator light are electrically connected to the main control module 13.

[0035] The indicator light is used to indicate the state of the switch button 16, and the light guide column is used to converge the light of the indicator light onto the switch button 16. The switch button 16 provides the user with on / off operations.

[0036] In some embodiments, the main board 14 is further provided with a Type-C interface 17 and a data storage module. The Type-C interface 17 exposes from the rear shell 112. Both the Type-C interface 17 and the data storage module are electrically connected to the main control module 13.

[0037] The Type-C interface 17 facilitates the connection of the fingertip wearable spectral sensing glove 1 to an external power source, and the data storage module is used to temporarily store the data collected by the spectral chip 12.

[0038] In some embodiments, the main control module 13 includes a Bluetooth communication unit for Bluetooth connection with the smart terminal 2.

[0039] The Bluetooth communication unit is used to establish a communication connection between the fingertip wearable spectral sensing glove 1 and the smart terminal 2, and to realize data interaction between the fingertip wearable spectral sensing glove 1 and the smart terminal 2.

[0040] In some embodiments, the fingertip wearable spectral sensing glove 1 further includes a number of silicone pads with different thicknesses. The silicone pads are detachably installed in the light-shielding cavity 110 to adjust the internal size of the light-shielding cavity 110.

[0041] Users can put in the corresponding number of silicone pads according to the size of their fingers. Moreover, the silicone pads are made of soft material and have good air permeability, making it more comfortable for users to wear.

[0042] When using the fingertip wearable spectral sensing glove 1 of the present application, the user puts their finger into the light-shielding cavity 110, and can non-invasively collect the characteristic spectral data of the arterial blood vessel projection area of the user through the fingertip, so as to collect the physiological data of the user, avoiding invasive operations that may be involved in traditional monitoring methods, such as blood drawing, etc. Moreover, the fingertip wearable spectral sensing glove 1 cleverly combines the ergonomic principle, with high user wearing comfort. The light-shielding cavity 110 that can adjust the size adapts to the sizes of different users' fingers, is convenient to wear, does not require long-term wearing, avoids the discomfort of long-term wearing, and can also avoid the problem of poor fitting of wrist-mounted devices. At the same time, the spectral chip can emit and receive optical signals of multiple different wavelengths, and the main control module forwards the data of the spectral chip to the intelligent terminal 2 for analysis, so as to be able to monitor various types of physiological and health indicators of the user.

[0043] Based on the above-mentioned fingertip wearable spectral sensing glove 1, a method for a fingertip wearable spectral sensor to sense health is provided, which is executed by the main control module 13 of the fingertip wearable spectral sensing glove 1, as Figure 5 shown, including the following steps S101 to step S103.

[0044] S101. The main control module controls the spectral chip to collect the characteristic spectral data corresponding to the arterial blood vessel projection area of the user according to the received index monitoring instruction; the characteristic spectral data is obtained based on the emission and reception of one or more lights between ultraviolet light and near-infrared light.

[0045] After the user wears the fingertip wearable spectral sensing glove, the user can press the switch button of the fingertip wearable spectral sensing glove to start the fingertip wearable spectral sensing glove. Since the shape of the shell of the fingertip wearable spectral sensing glove is similar to that of a finger, the shell also has a pulp position, and a spectral chip is arranged at the pulp position. The user can then put the finger into the light-shielding cavity and press the pulp of the finger with the fingertip wearable spectral sensing glove on the position of the arterial blood vessel projection area to be measured, so that the spectral chip is aligned with the arterial blood vessel projection area of the user to be measured. The person to be measured can be the user wearing the fingertip wearable spectral sensing glove himself or herself, or someone else, which is not limited here.

[0046] In some embodiments, the arterial blood vessel projection area of the user may include the finger root position of the user, the wrist artery position, the carotid artery position, the femoral artery position, etc. The finger root position may be selected as the finger root of the index finger, the middle finger or the ring finger.

[0047] In some embodiments, the spectral chip includes a broad-spectrum dot matrix light emission module from ultraviolet light to near-infrared light and an optical signal receiving module for different reflected light wavelengths.

[0048] The broad-spectrum dot matrix light emission module can emit optical signals from ultraviolet light to near-infrared light, and the optical signal receiving module is correspondingly arranged, that is, the optical signals emitted by the broad-spectrum dot matrix light emission module are received and processed by the corresponding optical signal receiving module.

[0049] Furthermore, the spectral chip includes four functional areas. The first to third functional areas are broad-spectrum dot matrix light emission modules. The first functional area includes multiple ultraviolet emitters with an emission wavelength range of 200nm - 400nm; the second functional area includes multiple visible light emitters with an emission wavelength range of 400nm - 800nm; the third functional area includes multiple near-infrared emitters with an emission wavelength range of 800nm - 1700nm; the fourth functional area is the optical signal receiving module. Among them, the fourth functional area includes a first detection window and a second detection window. The first detection window includes one or more CMOS (Complementary Metal Oxide Semiconductor) detectors for detecting the wavelength range of 200nm - 1000nm, and the second detection window includes one or more InGaAs (Indium Gallium Arsenide) detectors for detecting the wavelength range of 1000nm - 1700nm.

[0050] The spectral chip of the present application has multiple light sources and can meet more usage scenarios.

[0051] In some embodiments, the fingertip wearable spectral sensing glove is communicatively connected to the smart terminal, such as Bluetooth connection, to achieve data interaction between the fingertip wearable spectral sensing glove and the smart terminal. The user can send corresponding index monitoring instructions to the fingertip wearable spectral sensing glove through the smart terminal according to the health monitoring requirements. Then, when the fingertip wearable spectral sensing glove controls the spectral chip to collect the characteristic spectral data of the user's arterial blood vessel projection area, the optical signal sent is the optical signal corresponding to the wavelength of the index.

[0052] For example, if the user wishes to detect the resting heart rate, blood oxygen saturation, and heart rate variability of the user to be measured, the smart terminal sends monitoring instructions related to the resting heart rate, blood oxygen saturation, and heart rate variability to the fingertip wearable spectral sensing glove. After receiving the monitoring instructions, the fingertip wearable spectral sensing glove controls the spectral chip to emit optical signals of 530nm, 660nm, and 940nm to the arterial blood vessel projection area of the user to be measured. The spectral chip receives the returned optical signals, thereby collecting characteristic spectral data corresponding to the monitoring instructions related to the heart rate, blood oxygen, and heart rate variability of the user.

[0053] For another example, if the user wishes to monitor the blood glucose data of the user to be measured, the smart terminal sends monitoring instructions related to blood glucose to the fingertip wearable spectral sensing glove. After receiving the monitoring instructions, the fingertip wearable spectral sensing glove controls the spectral chip to emit optical signals of 880nm, 940nm, 1050nm, 1100nm, 1200nm, and 1300nm to the arterial blood vessel projection area of the user to be measured. The spectral chip receives the returned optical signals, thereby collecting characteristic spectral data corresponding to the monitoring instructions related to blood glucose of the user.

[0054] Since the spectral chip has multiple light sources, the smart terminal can send different monitoring instructions, enabling the spectral chip to emit optical signals of different wavelengths and, at the same time, receive optical signals of the corresponding wavelengths, thereby calculating the characteristic spectral data corresponding to the arterial blood vessel projection area of the user, facilitating the user to monitor different physiological health indicators in a personalized manner.

[0055] S102. The main control module receives the characteristic spectral data sent by the spectral chip and calculates a calibrated spectral value based on the characteristic spectral data.

[0056] Since this fingertip wearable spectral sensing glove can be used in any light environment, directly collecting the original characteristic spectral data may be easily interfered by external light. Therefore, it is necessary to compensate for the interference of ambient light.

[0057] In some embodiments, step S102 may include: The main control module turns off the broad-spectrum dot matrix light emission module and receives the first characteristic spectral data collected by the optical signal receiving module under ambient light as the background noise template; The main control module turns on the broad-spectrum dot matrix light emission module so that the broad-spectrum dot matrix light emission module emits optical signals of wavelengths corresponding to the index monitoring instructions and receives the second characteristic spectral data collected by the optical signal receiving module under normal light sources; The main control module performs differential calculation on the background noise template and the second characteristic spectral data to obtain a calibrated spectral value.

[0058] Specifically, for each indicator that needs to be monitored, the fingertip wearable spectral sensing glove usually needs to collect data twice. The first time is when the spectral chip on the fingertip of the fingertip wearable spectral sensing glove is aligned with the arterial blood vessel projection area of the user, and the main control module turns off the broad-spectrum dot matrix light emission module. The optical signal receiving module collects the first characteristic spectral data under ambient light as the background noise template. The second time is when the spectral chip on the fingertip of the fingertip wearable spectral sensing glove still remains aligned with the arterial blood vessel projection area of the user, and the main control module turns on the broad-spectrum dot matrix light emission module. The broad-spectrum dot matrix light emission module emits an optical signal with a wavelength corresponding to the indicator monitoring instruction to the arterial blood vessel projection area of the user, and the optical signal receiving module collects the second characteristic spectral data reflected from the arterial blood vessel projection area of the user under normal light sources. The main control module obtains this second characteristic spectral data. During calibration, the main control module performs a differential calculation on the background noise template and the second characteristic spectral data through the following formula: ; Among them, represents the calibrated spectral value, J represents the second characteristic spectral data, and A represents the first characteristic spectral data.

[0059] By calibrating the characteristic spectral data, the optical interference during monitoring caused by ambient light is avoided.

[0060] S103. The main control module sends the calibrated spectral value to the intelligent terminal for the intelligent terminal to calculate the physiological health indicator corresponding to the indicator monitoring instruction based on the calibrated spectral value, analyze and process the physiological health indicator, and push a personalized adjustment plan.

[0061] After receiving the calibrated spectral value, the intelligent terminal calculates the physiological health indicator and analyzes and processes the physiological health indicator. Details can be found in the method for sensing health based on fingertip wearable spectral sensors applied to the intelligent terminal later.

[0062] In the embodiments of the present application, the user wears the fingertip wearable spectral sensing glove on the finger. After the fingertip wearable spectral sensing glove is turned on, the user presses the finger wearing the fingertip wearable spectral sensing glove onto any arterial blood vessel projection area of the user to be measured. Since the arterial blood vessels are relatively rich, the spectral chip of the fingertip wearable spectral sensing glove can non-destructively collect the characteristic spectral data of the arterial blood vessel projection area of the finger of the user. Moreover, the characteristic spectral data is obtained based on the emission and reception of one or more light signals between ultraviolet light and near-infrared light. The main control module sends the rich characteristic spectral data to the intelligent terminal, and the intelligent terminal can quickly and accurately calculate a variety of physiological and health indicators that the user hopes to monitor, not limited to the traditional heart rate and blood oxygen monitoring. The intelligent terminal further analyzes and processes the physiological and health indicators, provides the user with real-time health status evaluation and personalized suggestions, enables the user to make timely health decisions based on real-time data, and ensures the personal health of the user.

[0063] As Figure 6 shown, the present application also provides a method for perceiving health based on a fingertip wearable spectral sensor, which is applied to an intelligent terminal. The intelligent terminal is communicatively connected to the fingertip wearable spectral sensing glove. The method for perceiving health based on the fingertip wearable spectral sensor includes steps S201 to S204.

[0064] S201. Send an index monitoring instruction to the fingertip wearable spectral sensing glove, so that the fingertip wearable spectral sensing glove controls the spectral chip to collect the characteristic spectral data corresponding to the arterial blood vessel projection area of the user according to the index monitoring instruction, and calculates the calibration spectral value; S202.

Analyze and process the physiological and health indicators to obtain an analysis result; S204. Push a personalized adjustment plan according to the analysis result.

[0065] In some embodiments, the index monitoring instructions include a heart rate monitoring instruction, a blood oxygen monitoring instruction, a heart rate variability monitoring instruction, a stress monitoring instruction, and a fatigue monitoring instruction; the physiological and health indicators include resting heart rate, blood oxygen saturation, heart rate variability, stress index, and fatigue; then step S202 may include: Calculate the resting heart rate, blood oxygen saturation, and heart rate variability according to the reflection algorithm and the calibration spectral value; wherein, the calibration spectral value is calculated based on the light signals emitted by the broad-spectrum dot matrix light emission module of the fingertip wearable spectral sensing glove in the ultraviolet to near-infrared range.

[0066] Specifically, when the index monitoring instructions are for resting heart rate, blood oxygen saturation, heart rate variability, stress monitoring, and fatigue monitoring, the broad-spectrum dot matrix light emission module of the spectral chip can emit light signals of 530nm, 660nm, and 940nm to the arterial blood vessel projection area of the user. The light signal receiving module receives the reflected light signals, and the main control module sends the corresponding calibrated spectral values to the smart terminal for the smart terminal to calculate the heart rate, blood oxygen, and heart rate variability.

[0067] The spectral chip emits light signals with a wavelength of 530nm and receives the reflected light signals. The smart terminal can calculate the physiological health index of heart rate based on the calibrated spectral values sent by the fingertip wearable spectral sensing glove, and further calculate the physiological health index of heart rate variability. By emitting light signals with wavelengths of 660nm and 940nm, the blood oxygen saturation, a physiological health index, can be calculated.

[0068] It can be understood that using emission algorithms and spectral values to calculate resting heart rate, blood oxygen saturation, and heart rate variability belongs to relatively mature technologies in this field and will not be elaborated here.

[0069] After calculating the heart rate, blood oxygen, and heart rate variability, the smart terminal calculates the stress index based on the heart rate variability and the heart rate.

[0070] Furthermore, the stress index can be calculated through the following formula: Stress index = (real-time heart rate value - standard heart rate value) × 0.4 + (real-time RMSSD value of heart rate variability - standard RMSSD value of heart rate variability) × 0.6.

[0071] The calculation of fatigue is based on the scores corresponding to resting heart rate, blood oxygen saturation, heart rate variability, and stress index respectively, and the analysis and processing of the indicators will be described in detail later.

[0072] The user can send the above index monitoring instructions to the fingertip wearable spectral sensing glove separately on the smart terminal to monitor a single index, or send multiple index monitoring instructions simultaneously to monitor multiple indices.

[0073] When the index monitoring instruction is for blood glucose monitoring, the broad-spectrum dot matrix light emission module of the spectral chip can emit light signals from near-infrared to short-wave infrared to the arterial blood vessel projection area of the user. The light signal receiving module receives the reflected light signals, and the main control module sends the corresponding calibrated spectral values to the smart terminal for the smart terminal to calculate blood glucose data using a non-linear neural network algorithm model based on the blood glucose values and calibrated spectral values of the user at multiple time periods.

[0074] Among them, when monitoring blood glucose, the specific wavelengths emitted by the broad-spectrum dot matrix light emission module are 880nm, 940nm, 1050nm, 1100nm, 1200nm, and 1300nm.

[0075] The user can operate on the intelligent terminal according to the monitoring requirements, so that the intelligent terminal can send an index monitoring instruction corresponding to the monitoring requirements, enabling the fingertip wearable spectral sensing glove to monitor the corresponding calibration spectral value and transmit it back to the intelligent terminal for calculating physiological health indicators. Moreover, there are a wide variety of physiological health indicators, which can meet most of the user's monitoring needs, have strong practicability, avoid invasive operations that may be involved in traditional monitoring methods, and are easy to operate.

[0076] In some of the embodiments, step S203 may include: Score the resting heart rate, the blood oxygen saturation, the heart rate variability, and the stress index respectively to obtain a heart rate abnormality score, a blood oxygen abnormality score, a heart rate variability abnormality score, and a stress abnormality score.

[0077] Based on the heart rate abnormality score, the heart rate variability abnormality score, and the stress abnormality score, calculate the fatigue degree and score the fatigue degree to obtain a fatigue score; Calculate the total health score according to the resting heart rate, blood oxygen saturation, heart rate variability, stress value, and fatigue degree.

[0078] Specifically, referring to Table 1 below, score the resting heart rate, the blood oxygen saturation, the heart rate variability, and the stress index respectively to obtain a heart rate abnormality score, a blood oxygen abnormality score, a heart rate variability abnormality score, and a stress abnormality score.

[0079] Table 1 Based on the heart rate abnormality score, the heart rate variability abnormality score, and the stress abnormality score, the fatigue degree can be calculated by the following formula: Fatigue degree MPFFI = (heart rate abnormality score × 0.35) + (RMSSD abnormality score × 0.35) + (stress abnormality score × 0.3).

[0080] Among them, heart rate abnormality score = (resting heart rate - 60) / 2, and when the heart rate is greater than 100, heart rate abnormality score = (resting heart rate - 100) / 2.

[0081] RMSSD anomaly score = (RMSSD real-time value of heart rate variability - RMSSD baseline value of heart rate variability) / 0.4, and when the RMSSD real-time value of heart rate variability is less than the minimum value of the RMSSD baseline value of heart rate variability, RMSSD anomaly score = (RMSSD real-time value of heart rate variability - minimum value of the RMSSD baseline value of heart rate variability) / 0.4; when the RMSSD real-time value of heart rate variability is greater than the maximum value of the RMSSD baseline value of heart rate variability, RMSSD anomaly score = (RMSSD real-time value of heart rate variability - maximum value of the RMSSD baseline value of heart rate variability) / 0.4.

[0082] It can be understood that the normal lower limit of RMSSD for healthy adults is about 20 ms.

[0083] Stress anomaly score = (stress index - 5) / 0.25.

[0084] According to the resting heart rate, blood oxygen saturation, variability heart rate, stress value, and fatigue level, calculate the total health score, which is expressed by the following formula: Total health score = 100 - ((real-time heart rate - standard heart rate) * 0.5 + (blood oxygen saturation - standard blood oxygen) * 4 + (real-time HRV - standard HRV) * 2.5 + (real-time stress value - standard stress value) * 4 + (real-time fatigue level value - standard fatigue level value) * 5) Among them, the baseline standard is that the 7-day moving average of the automatically measured RMSSD per week is used as the new baseline. HRV represents the variability heart rate, and RMSSD is a representative index of heart rate variability, which is the root mean square of the differences between adjacent normal cardiac cycles.

[0085] In some embodiments, according to the analysis results, a personalized adjustment plan is pushed, which may include: If the number of consecutive abnormal occurrences of any one of the heart rate anomaly score, blood oxygen anomaly score, variability heart rate anomaly score, stress anomaly score, and fatigue score exceeds a preset number of times, and the preset number of times can be 3 times, then a yellow warning is issued; If the total health score is lower than the first health score threshold and the duration reaches the first preset duration, the first health score threshold can be 90 points, and the first preset duration can be 7 days, then an orange warning is issued;

[0086] If the total health score is lower than the second health score threshold, the duration reaches the second preset duration, the second health score threshold can be 80 points, the second preset duration can be 3 days, and the abnormal index of any one indicator is greater than the preset index. For example, the blood oxygen saturation is lower than 90%, the heart rate is lower than 40 beats / min, or higher than 220 beats / min, then a red warning is issued; Among them, the first health score threshold is greater than the second health score threshold, and the first preset duration is greater than the second preset duration.

[0087] Push a personalized adjustment plan according to the scores of various physiological health indicators, the yellow warning, orange warning and / or red warning.

[0088] By scoring various physiological health indicators of the user and generating corresponding warnings, the physiological health status of the user can be reminded.

[0089] In some embodiments, the pushing of the personalized adjustment plan includes: If the abnormal stress score exceeds the preset stress score, recommend breathing training; If the fatigue score exceeds the preset fatigue score, suggest that the user reduce the amount of exercise; If the blood oxygen saturation is lower than the blood oxygen threshold, suggest that the user seek medical attention immediately.

[0090] For example, when the stress index is too high, recommend breathing training; when the fatigue level exceeds the standard, suggest reducing the amount of exercise; when the blood oxygen saturation is too low, suggest that the user seek medical attention immediately, etc.

[0091] Or, if the fatigue level is too low and other indicators are normal, aerobic exercise, anaerobic exercise, etc. can also be recommended to the user, which is not limited here.

[0092] Based on the scores of various physiological health indicators and various warnings, pushing a personalized adjustment plan to the user can help the user make scientific health decisions.

[0093] In this application, the user wears the fingertip wearable spectral sensing glove on the finger. After the fingertip wearable spectral sensing glove is turned on, the user presses the finger wearing the fingertip wearable spectral sensing glove onto any arterial blood vessel projection area of the user to be measured according to their own needs. The arterial blood vessels are relatively rich, so that the spectral chip of the fingertip wearable spectral sensing glove can non-destructively collect the characteristic spectral data of the user's arterial blood vessel projection area. And, the characteristic spectral data is obtained based on the emission and reception of one or more lights between ultraviolet light and near-infrared light. The main control module sends the rich characteristic spectral data to the intelligent terminal. The intelligent terminal can quickly and accurately calculate a variety of physiological health indicators that the user hopes to monitor, not limited to traditional heart rate and blood oxygen monitoring. The intelligent terminal further analyzes and processes the physiological health indicators, provides the user with real-time health status evaluation and personalized suggestions, enables the user to make timely health decisions based on real-time data, and guarantees the personal health of the user.
