[0024] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0026] In the following, in conjunction with the accompanying drawings, a ring-shaped wearable device and a control method provided in an embodiment of the present application are described in detail through specific embodiments and their application scenarios.

[0027] See also Figure 1-Figure 5The embodiment of the present application provides a ring-shaped wearable device, the ring-shaped wearable device comprising: an inner ring body 100, an outer ring body 200, a biosensor 300, a circuit board and a driving component 400, the outer ring body 200 is provided with a receiving cavity 210, the inner ring body 100, the circuit board and the driving component 400 are respectively arranged in the receiving cavity 210, the biosensor 300 is fixedly connected to the inner ring body 100, and the biosensor 300 and the driving component 400 are respectively electrically connected to the circuit board;

[0028] The inner ring body 100 is coaxially arranged with the outer ring body 200, the driving component 400 is connected to the inner ring body 100, and the circuit board is used to control the driving component 400 to drive the inner ring body 100 to rotate around the axis of the inner ring body 100 relative to the outer ring body 200 according to the signal quality of the biosensor 300.

[0029] The above-mentioned annular wearable device can be various annular smart wearable devices, for example, it can be a smart ring, a smart bracelet, a smart armband, a smart watch, etc. For ease of understanding, the structure and working principle of the annular wearable device provided in the embodiment of the present application are further explained below by taking the annular wearable device as a smart ring as an example.

[0030] The inner ring body 100 and the outer ring body 200 may be in the shape of a ring respectively. The outer ring body 200 may be a hollow structure to form the accommodating cavity 210 in the outer ring body 200 , and the accommodating cavity 210 may be an annular accommodating cavity 210 , and the axis of the annular accommodating cavity 210 coincides with the axis of the outer ring body 200 .

[0031] The above-mentioned biosensor 300 may be various biosensors 300 for detecting human physiological data, wherein the human physiological data may be healthy physiological data such as heart rate, blood oxygen, body temperature, and sleep.

[0032] The above-mentioned circuit board can be various control circuit boards or control chips in the ring-shaped wearable device. The driving component 400 can be various driving components 400 that can drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100, for example, various driving components 400 similar in principle to brushless motors, or other driving components 400 with the same function.

[0033] The signal quality of the above-mentioned biosensor 300 may refer to the signal quality of the detection signal output by the biosensor 300, wherein the signal quality evaluation method in the embodiment of the present application may be evaluated by various common signal quality evaluation methods in the related art. For example, the following evaluation methods may be used for evaluation: signal-to-noise ratio (SNR), bit error rate (BER), channel capacity, signal strength test, noise test, linear distortion and nonlinear distortion test, etc.

[0034] See also Figure 3 , is a schematic diagram of the distribution of arterial vessels in the palm of the human body, wherein the reference numeral A is the palmar artery, and the reference numeral B is the thumb artery. The palmar artery A is located on the side of the finger. Taking the ring-shaped wearable device as a smart ring as an example, since the biosensor 300 mainly emits light through the light-emitting element, after the light penetrates the skin tissue, a part of it is absorbed and a part is emitted. The relevant detection elements in the biosensor 300 detect the intensity change of the reflected light and convert it into a digital signal, and the algorithm calculates and outputs the relevant physiological indicators, which include heart rate, blood oxygen, etc. Among them, the above-mentioned reflected light is mainly reflected by blood. Therefore, when the biosensor 300 in the smart ring is facing the palmar artery A, the data collection effect is usually better. When the biosensor 300 of the smart ring is facing other positions other than the palmar artery A, the data collection effect is poor. Among them, the above-mentioned signal quality is positively correlated with the reflection effect of the reflected light, and different reflected lights are converted into different digital signals. Therefore, the correspondence between different digital signals and signal qualities can be determined in advance. In this way, the strength of the signal quality can be determined according to the correspondence through the digital signal output by the biosensor 300.

[0035] It can be understood that in the process of the driving component 400 driving the inner ring body 100 to rotate relative to the outer ring body 200, the relative position between the outer ring body 200 and the finger remains unchanged, and the inner ring body 100 drives the biosensor 300 to rotate around the finger. In this way, it is only necessary to rotate the biosensor 300 to a position relative to the palmar artery A to improve the signal quality of the signal output by the biosensor 300, thereby improving the accuracy of the physiological data output by the ring-shaped wearable device.

[0036] In this embodiment, when the annular wearable device is in a worn state, the driving component 400 can be controlled by the circuit board according to the signal quality of the biosensor 300 to drive the inner ring body 100 to rotate around the axis of the inner ring body 100 relative to the outer ring body 200, and the biosensor 300 is fixedly connected to the inner ring body 100. Therefore, during the rotation of the inner ring body 100, the biosensor 300 can be driven to rotate synchronously, which is beneficial to rotate the biosensor 300 to a position with better signal quality. In this way, the data acquisition effect of the biosensor 300 can be improved, which is beneficial to improve the accuracy of the physiological data output by the annular wearable device.

[0037] Optionally, the inner side wall of the outer ring body 200 is provided with an annular opening 220 opposite to the inner side wall of the inner ring body 100, the axis of the annular opening 220 coincides with the axis of the outer ring body 200, the biosensor 300 is embedded in the inner side wall of the inner ring body 100, and the detection part of the biosensor 300 faces the annular opening 220;

[0038] The inner wall of the inner ring body 100 is located outside the inner wall of the outer ring body 200 , and the inner wall of the inner ring body 100 blocks the annular opening 220 . The inner wall of the inner ring body 100 and the inner wall of the outer ring body 200 form a step position 230 at the edge of the annular opening 220 .

[0039] See also Figure 1 and Figure 2 , the inner side wall of the outer ring body 200 refers to: the innermost side wall of the outer ring body 200, that is, the side wall of the outer ring body 200 facing the center hole thereof. Correspondingly, the inner side wall of the inner ring body 100 refers to: the innermost side wall of the inner ring body 100, that is, the side wall of the inner ring body 100 facing the center hole thereof. The width of the inner side wall of the inner ring body 100 may be greater than the width of the annular opening 220, so that the inner side wall of the inner ring body 100 may block the annular opening 220, thereby achieving sealing of the accommodating cavity 210.

[0040] Please see further Figure 2Since the inner wall of the inner ring body 100 and the inner wall of the outer ring body 200 form a step position 230 at the edge of the annular opening 220, when the user wears the annular wearable device, the distance between the inner wall of the inner ring body 100 and the user's skin is greater than the distance between the inner wall of the outer ring body 200 and the user's skin. In this way, the inner wall of the outer ring body 200 can directly contact the user's skin, while the distance between the inner wall of the inner ring body 100 and the user's skin is relatively large. Therefore, the contact between the inner wall of the inner ring body 100 and the user's skin can be reduced. In this way, in the driving component 4 During the process of driving the inner ring body 100 to rotate relative to the outer ring body 200, since the outer ring body 200 is in direct contact with the user's skin, the friction between the outer ring body 200 and the user's skin is poor. Therefore, during this process, the relative position between the outer ring body 200 and the user's skin remains unchanged, and the friction between the inner ring body 100 and the user's skin is small. Therefore, the driving component 400 can drive the inner ring body 100 to rotate relative to the outer ring body 200. During this process, the inner ring body 100 can also rotate relative to the user's skin, so as to cover the position between the biosensor 300 and the user's skin.

[0041] The detection part of the above-mentioned biosensor 300 refers to: a collection part for collecting reflected light from skin tissue, that is, the part of the biosensor 300 that is opposite to the object to be detected. The detection part can also be called a sensing surface or a detection surface.

[0042] It should be noted that, when the driving assembly 400 drives the inner ring body 100 to rotate, the biosensor 300 can make a circular motion around the axis of the annular opening 220 , and the detection part of the biosensor 300 can always face the annular opening 220 .

[0043] In this embodiment, an annular opening 220 is provided on the inner side wall of the outer ring body 200, which is opposite to the inner side wall of the inner ring body 100, and the detection part of the biosensor 300 is directed toward the annular opening 220. In this way, when the user wears the annular wearable device, the detection part can pass through the annular opening 220 and face the user's skin, thereby facilitating the biosensor 300 to collect the user's health and physiological data. In addition, by forming a step position 230 at the edge of the annular opening 220 between the inner side wall of the inner ring body 100 and the inner side wall of the outer ring body 200, the friction between the inner ring body 100 and the user's skin can be reduced, thereby facilitating the drive assembly 400 to drive the inner ring body 100 to rotate relative to the user's finger.

[0044] Optionally, the friction coefficient of the inner wall of the inner ring body 100 is smaller than the friction coefficient of the inner wall of the outer ring body 200 .

[0045] In some embodiments of the present application, in order to increase the friction coefficient of the inner side wall of the outer ring body 200, a high-friction frosting process can be used to process the inner side wall of the outer ring body 200 to increase the friction between the inner side wall of the outer ring body 200 and the user's finger. In addition, the inner side wall of the inner ring body 100 can also be polished to reduce the friction coefficient of the inner side wall of the inner ring body 100, thereby reducing the friction between the inner side wall of the inner ring body 100 and the user's finger.

[0046] In this embodiment, by making the friction coefficient of the inner wall of the inner ring body 100 smaller than the friction coefficient of the inner wall of the outer ring body 200, it is helpful to increase the friction between the inner wall of the outer ring body 200 and the user's finger, so that the relative position between the outer ring body 200 and the user's finger remains unchanged during the rotation of the inner ring body 100, and it is helpful to reduce the friction between the inner wall of the inner ring body 100 and the user's finger, thereby facilitating the control of the rotation of the inner ring body 100 relative to the user's finger.

[0047] Optionally, the accommodating cavity 210 includes a first annular inner wall, and the first annular inner wall is opposite to the outer wall of the inner ring body 100;

[0048] The driving assembly 400 includes a first driving module and a second driving module, one of the first driving module and the second driving module is disposed on the first annular inner wall, and the other is disposed on the outer wall of the inner ring body 100, and the first driving module and the second driving module are disposed opposite to each other;

[0049] The first driving module includes a plurality of magnetic members 410, which are arranged around the axis of the inner ring body 100, and the polarities of the end surfaces of any two adjacent magnetic members 410 facing the second driving module are opposite;

[0050] The second driving module includes a plurality of conductive coils 420, which are arranged around the axis of the inner ring body 100, and the plurality of conductive coils 420 are electrically connected to the circuit board respectively, and one end of the conductive coil 420 is opposite to the first driving module.

[0051] The outer side wall of the inner ring body 100 refers to the outermost side wall of the inner ring body 100. The outer side wall of the inner ring body 100 and the inner side wall of the inner ring body 100 are two opposite side walls of the inner ring body 100.

[0052] It is understandable that the positions of the first drive module and the second drive module can be interchanged and can be specifically set as needed. For example, in some embodiments of the present application, the first drive module can be set on the first annular inner wall, and the second drive module can be set on the outer wall of the inner ring body 100. For another example, in some other embodiments of the present application, the second drive module can be set on the first annular inner wall, and the first drive module can be set on the outer wall of the inner ring body 100. Please refer to Figure 1 In the following, the structure of the ring-shaped wearable device provided in the embodiment of the present application is further explained by taking the example that the first driving module is arranged on the first annular inner wall and the second driving module is arranged on the outer wall of the inner ring body 100.

[0053] The magnetic member 410 may be any type of magnetic member 410, for example, a magnet block, an electromagnet, etc. Figure 1 , among the plurality of magnetic members 410, the end faces of any two adjacent magnetic members 410 facing the second driving module have opposite polarities, which means that the north and south poles of the plurality of magnetic members 410 are alternately facing the axis of the inner ring body 100. The plurality of magnetic members 410 are arranged around the axis of the inner ring body 100, which means that the plurality of magnetic members 410 are arranged along the circumferential direction of the first annular inner wall.

[0054] One end of the conductive coil 420 being opposite to the first drive module may mean that the axis of the conductive coil 420 is facing the first drive module. For example, in some embodiments of the present application, the extension direction of the axis of the conductive coil 420 may be the radial direction of the inner ring body 100. By making one end of the conductive coil 420 opposite to the first drive module, by energizing the conductive coil 420, the end of the conductive coil 420 facing the first drive module can be equivalent to the south pole or north pole of a magnet. In order to facilitate the installation of the conductive coil 420, please refer to Figure 1 , a plurality of windings 430 arranged along the circumferential direction may be provided on the surface of the outer wall of the inner ring body 100, and a coil may be installed on each winding 430, wherein the coil may be wound or sleeved on the corresponding winding 430 to achieve a fixed connection between the coil and the outer wall of the inner ring body 100, and to achieve a fixed position of the coil. The plurality of conductive coils 420 arranged around the axis of the inner ring body 100 may refer to: the plurality of conductive coils 420 are arranged along the circumferential direction of the outer wall of the inner ring body 100.

[0055] It is understandable that the driving principle of the driving assembly 400 is the same as the driving principle of the brushless motor in the related art. Figure 1When the drive assembly 400 moves to Figure 1 When the position is shown, you can Figure 1 The four conductive coils 420 in the embodiment are marked as conductive coil 1, conductive coil 2, conductive coil 3 and conductive coil 4 in the clockwise direction. Figure 1 The five magnetic members 410 in the embodiment are marked as magnetic member 1, magnetic member 2, magnetic member 3, magnetic member 4 and magnetic member 5 in the clockwise direction. Since each conductive coil 420 is directly opposite to the junction of two adjacent magnetic members 410, and the polarities of the end faces of the two adjacent magnetic members 410 facing the corresponding conductive coil 420 are opposite, when the end of the conductive coil 1 facing the magnetic member 1 is opposite to the polarity of the magnetic member 1, the polarity of the conductive coil 1 and the magnetic member 2 are the same. According to the principle that like charges repel and opposite charges attract, the conductive coil 1 will move toward the magnetic member 1. The inner ring body 100 rotates in the direction close to the magnetic part 1 and away from the magnetic part 2. At this time, the energizing direction of the conductive coil 2 can be opposite to that of the conductive coil 1, the energizing direction of the conductive coil 3 can be the same as that of the conductive coil 1, and the energizing direction of the conductive coil 4 can be opposite to that of the conductive coil 1. In this way, according to the same principle, the conductive coils 1, 2, 3 and 4 can all drive the inner ring body 100 to rotate in the counterclockwise direction through the corresponding windings 430, thereby realizing the relative rotation between the inner ring body 100 and the outer ring body 200. Accordingly, when it is necessary to control the inner ring body 100 to rotate clockwise relative to the outer ring body 200, it is sufficient to change the energizing directions of the conductive coils 1, 2, 3 and 4.

[0056] It is understandable that the first drive module and the second drive module can be arc-shaped or annular, and the larger the central angle of the first drive module and the second drive module, the larger the travel range of the inner ring body 100. When the first drive module and the second drive module are both annular, that is, the first drive module covers the entire circumference of the first annular inner wall, and the second drive module covers the entire circumference of the outer wall of the inner ring body 100, at this time, the travel range of the inner ring body 100 is the largest, and the inner ring body 100 can rotate a full circle relative to the outer ring body 200.

[0057] In this embodiment, the first driving module includes a plurality of magnetic members 410, and the polarities of the end faces of any two adjacent magnetic members 410 facing the second driving module are opposite. The second driving module includes a plurality of conductive coils 420. In this way, the circuit board only needs to control the power supply direction of the conductive coils 420 to control the forward or reverse rotation of the inner ring body 100 relative to the outer ring body 200, thereby driving the biosensor 300 to rotate to a position with strong signal quality.

[0058] Optionally, the first driving module and the second driving module are respectively ring-shaped.

[0059] In this embodiment, the first driving module and the second driving module are respectively annular, that is, the first driving module covers the entire circumference of the first annular inner wall, and the second driving module covers the entire circumference of the outer wall of the inner ring body 100. At this time, the travel range of the inner ring body 100 is the largest, which is beneficial to increase the position adjustment range of the biosensor 300 to ensure that the biosensor 300 can rotate to a position with strong signal quality.

[0060] Optionally, the annular wearable device is a smart ring, and the biosensor 300 includes a light-emitting body 310 and at least one photodiode 320 (Photo-Diode, PD), and the light-emitting body 310 and the at least one photodiode 320 are electrically connected to the circuit board respectively; the light-emitting body 310 and the at least one photodiode 320 are fixedly connected to the inner ring body 100 respectively.

[0061] The light emitting body 310 and the at least one photodiode 320 may be arranged in sequence along the inner side wall of the inner ring body 100 and around the axis of the inner ring body 100, that is, the light emitting body 310 and the at least one photodiode 320 may be located on the same circumference, wherein the axis of the circumference coincides with the axis of the inner ring body 100. For example, see Figure 4 When the number of the photodiodes 320 is two, the two photodiodes 320 and the light-emitting body 310 are arranged in sequence along the inner wall of the inner ring body 100 and around the axis of the inner ring body 100 , and the light-emitting body 310 is located between the two photodiodes 320 .

[0062] It can be understood that the light-emitting surface of the light-emitting body 310 and the light-sensitive surface of the photodiode 320 can face the annular opening 220. In this way, when the user wears the smart ring, the light-emitting body 310 can emit light to the user's finger. After the light penetrates the skin tissue, part of it is absorbed and part of it is emitted and received by the photodiode 320. The photodiode 320 can detect the intensity change of the reflected light and convert it into a digital signal, and send the digital signal to the circuit board. The circuit board can output relevant physiological indicators through algorithm calculation, and the physiological indicators include heart rate, blood oxygen, etc.

[0063] The above-mentioned light-emitting component can be various light-emitting bodies 310, for example, it can be a light-emitting diode (LED) lamp group, wherein the light-emitting component can emit red light, infrared light, green light and other light. After the light emitted by the LED lamp group passes through the skin tissue, part of it is absorbed by the skin and part of it is reflected.

[0064] In this embodiment, the biosensor 300 includes a light-emitting body 310 and at least one photodiode 320. Thus, when a user wears the smart ring, light can be emitted to the user's finger through the light-emitting body 310. After the light penetrates the skin tissue, part of it is absorbed and part of it is emitted and received by the photodiode 320. The photodiode 320 can detect the intensity change of the reflected light and convert it into a digital signal, and send the digital signal to the circuit board. The circuit board can output relevant physiological indicators through algorithm calculation, thereby realizing the function of detecting biological indicators.

[0065] See also Figure 6 , Figure 6 A flow chart of a control method provided in an embodiment of the present application is provided. The control method is applied to the circuit board of the ring-shaped wearable device described in the above embodiment. The method includes:

[0066] Step 601, control the driving component 400 to drive the inner ring body 100 to rotate around the axis of the inner ring body 100 relative to the outer ring body 200, so that the inner ring body 100 drives the biosensor 300 to rotate to the first position, wherein the signal quality of the biosensor 300 at the first position is stronger than or equal to the signal quality of the biosensor 300 at the second position, wherein the second position is the position of the biosensor 300 before the inner ring body 100 rotates.

[0067] Specifically, the signal quality of the biosensor 300 can be continuously detected during the process of controlling the rotation of the biosensor 300. In this way, when the biosensor 300 rotates to a position with better signal quality, the position can be determined as the first position, and the inner ring body 100 can be controlled to stop rotating, thereby driving the biosensor 300 to rotate to the first position.

[0068] In this embodiment, when the annular wearable device is in a worn state, the driving component 400 can be controlled by the circuit board according to the signal quality of the biosensor 300 to drive the inner ring body 100 to rotate around the axis of the inner ring body 100 relative to the outer ring body 200, and the biosensor 300 is fixedly connected to the inner ring body 100. Therefore, during the rotation of the inner ring body 100, the biosensor 300 can be driven to rotate synchronously, which is beneficial to rotate the biosensor 300 to a position with better signal quality. In this way, the data acquisition effect of the biosensor 300 can be improved, which is beneficial to improve the accuracy of the physiological data output by the annular wearable device.

[0069] Optionally, controlling the driving assembly 400 to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100 so that the inner ring body 100 drives the biosensor 300 to rotate to the first position includes:

[0070] Control the driving component 400 to drive the inner ring body 100 to rotate multiple times in a first direction relative to the outer ring body 200 around the axis of the inner ring body 100 with a first angle value as a step length until the inner ring body 100 rotates one circle, wherein each time the inner ring body 100 rotates one first angle value, the circuit board detects the signal quality of the biosensor 300 once, and obtains multiple signal quality values ​​corresponding to the multiple rotations, wherein the first position is a position corresponding to the maximum signal quality value among the multiple signal quality values, and the first direction is a clockwise direction or a counterclockwise direction;

[0071] The driving assembly 400 is controlled to drive the inner ring body 100 to rotate around the axis of the inner ring body 100 relative to the outer ring body 200, and when the inner ring body 100 drives the biosensor 300 to rotate to the first position, the inner ring body 100 is controlled to stop rotating.

In other embodiments of the present application, the first angle value can also be a relatively large angle value, for example, the value range of the first angle value is between 20°-50°.

[0073] The above-mentioned control of the driving component 400 to drive the inner ring body 100 to rotate multiple times in the first direction relative to the outer ring body 200 around the axis of the inner ring body 100 with a first angle value as a step length until the inner ring body 100 rotates one circle means: controlling the driving component 400 to drive the inner ring body 100 to rotate multiple times in the first direction relative to the outer ring body 200 around the axis of the inner ring body 100, wherein during the multiple rotations, each time it rotates by a first angle value, and after each rotation by a first angle value, a signal quality detection is performed once, so that multiple signal quality values ​​corresponding one to one to the multiple rotations can be obtained.

[0074] Specifically, when the user wears the ring wearable device, the signal quality of the current position is detected and recorded, which is recorded as F0. After the inner ring body 100 is controlled to rotate to the first angle value in sequence, the signal quality of the position is detected and recorded, which is recorded as F1, F2, F3, F4, ..., Fn. until it rotates a full circle. From F0 to Fn, the best signal quality Fmax and the corresponding inner ring body 100 angle Amax are sorted and the inner ring body 100 is controlled to rotate to the Amax position again, that is, the best signal quality position.

Then, the biosensor 300 is controlled to rotate to the first position, which is conducive to determining that the biosensor 300 can be rotated to a position with better signal quality, so as to improve the signal quality of the biosensor 300.

[0084] Optionally, controlling the driving assembly 400 to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100 so that the inner ring body 100 drives the biosensor 300 to rotate to the first position includes:

[0085] Control the driving assembly 400 to drive the inner ring body 100 to rotate at least twice relative to the outer ring body 200 around the axis of the inner ring body 100 with a second angle value as a step length in the direction of increasing the signal quality of the biosensor 300, until the signal quality of the biosensor 300 begins to weaken, wherein each time the inner ring body 100 rotates by one second angle value, the circuit board detects the signal quality of the biosensor 300 once, and obtains at least two signal quality values ​​corresponding to the at least two rotations, wherein the first position is a position corresponding to the largest signal quality value among the at least two signal quality values;

[0086] The driving assembly 400 is controlled to drive the inner ring body 100 to rotate around the axis of the inner ring body 100 relative to the outer ring body 200, and when the inner ring body 100 drives the biosensor 300 to rotate to the first position, the inner ring body 100 is controlled to stop rotating.

[0087] Wherein, the direction in which the signal quality of the biosensor 300 is enhanced is rotated at least twice until the signal quality of the biosensor 300 begins to weaken, and the method further includes: determining the direction in which the signal quality of the biosensor 300 is enhanced, which may specifically include: recording the signal quality of the biosensor 300 before the rotation, and recording it as the first signal quality; controlling the inner ring body 100 to rotate in the first direction by a second angle value, and recording the signal quality of the biosensor 300 at this time, and recording it as the second signal quality; if the second signal quality is greater than the first signal quality, then determining the first direction as the direction in which the signal quality is enhanced. If the second signal quality is less than the first signal quality, then controlling the inner ring body 100 to rotate in the second direction by two second angle values, and recording the signal quality of the biosensor 300 at this time, and recording it as the third signal quality; if the third signal quality is greater than the first signal quality, then determining the second direction as the direction in which the signal quality of the biosensor 300 is enhanced. The method further includes: if the third signal quality is less than the first signal quality, then determining the position of the biosensor 300 before the rotation as the first position, that is, determining the position corresponding to the first signal quality as the first position. Among them, one of the first direction and the second direction is a clockwise direction, and the other is a counterclockwise direction.

[0088] The value of the second angle value can be set as needed. In some embodiments of the present application, the second angle value can be a relatively small angle value, for example, the second angle value can be an angle value less than 5°. In other embodiments of the present application, the second angle value can also be a relatively large angle value, for example, the second angle value ranges from 20° to 50°.

[0089] The above-mentioned control of the driving component 400 to drive the inner ring body 100 to rotate at least twice relative to the outer ring body 200 around the axis of the inner ring body 100 toward the direction of increasing the signal quality of the biosensor 300 until the signal quality of the biosensor 300 begins to weaken means: controlling the driving component 400 to drive the inner ring body 100 relative to the outer ring body 200 around the axis of the inner ring body 100 toward the direction of increasing the signal quality of the biosensor 300 until the signal quality after the rotation is lower than the signal quality after the last rotation. For example, when the number of rotations of the inner ring body 100 is k times, in the process of 0 to (k-1) rotations, the signal quality before each rotation is less than or equal to the signal quality after the rotation; the signal quality before the kth rotation is greater than the signal quality after the rotation. At this time, the position after the (k-1)th rotation can be determined as the position with the best signal quality during this round of rotation, and therefore, the position after the (k-1)th rotation can be determined as the first position, and k is an integer greater than 1.

[0091] Step 801: determine the direction of signal quality enhancement;

[0092] Step 802, controlling the driving assembly 400 to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100 by a second angle value in a direction in which the signal quality of the biosensor 300 is enhanced;

[0093] Step 803, collecting the signal quality of the biosensor 300;

[0095] If yes, execute step 805, step 805, control the driving assembly 400 to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100 by a second angle value in a direction in which the signal quality of the biosensor 300 is enhanced, and stop controlling the inner ring body 100 to stop rotating;

[0096] If not, the process returns to step 802 until the inner ring body 100 stops rotating.

And since the inner ring body 100 does not necessarily need to rotate a full circle during each adjustment of the biosensor 300, it is conducive to saving the power consumption of the driving component 400.

[0098] Optionally, controlling the driving assembly 400 to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100 so that the inner ring body 100 drives the biosensor 300 to rotate to the first position includes:

[0099] When it is detected that the ring-shaped wearable device switches from a non-wearing state to a wearing state, the driving component 400 is controlled to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100, so that the inner ring body 100 drives the biosensor 300 to rotate to the first position; or

[0101] Specifically, the switching of the annular wearable device from a non-wearing state to a wearing state may specifically refer to: the process of the user wearing the annular wearable device. In some embodiments of the present application, since the annular wearable device may not be in the position with the best signal quality after being worn during the process of the user wearing the annular wearable device, when it is detected that the annular wearable device is switched from a non-wearing state to a wearing state, the driving component 400 may be controlled to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100, so that the inner ring body 100 drives the biosensor 300 to rotate to the first position, to ensure that after the user wears the annular wearable device, the annular wearable device can automatically adjust to a position with better signal quality.

[0102] The first duration may be a duration set as required, for example, 5 minutes, 10 minutes, 30 minutes or 1 hour, etc. Specifically, since the overall position of the annular wearable device may rotate due to some reasons after the user wears it, the position of the biosensor 300 may be adjusted once every first duration, which helps to ensure that the biosensor 300 is always in a position with relatively good signal quality.

[0103] In this embodiment, when it is detected that the annular wearable device switches from a non-wearing state to a wearing state, the driving component 400 is controlled to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100, so that the inner ring body 100 drives the biosensor 300 to rotate to the first position. In this way, it can be ensured that after the user wears the annular wearable device, the annular wearable device can automatically adjust to a position with better signal quality. In addition, when the device is in the wearing state, the driving component 400 is controlled to drive the inner ring body 100 to rotate relative to the outer ring body 200 around the axis of the inner ring body 100 every first period of time, so that the inner ring body 100 drives the biosensor 300 to rotate to the first position.
