It should be noted that, the functional film can be covered in the vicinity of the outer surface closest to the action part, and the position of the functional film can be adjusted according to the undulation of the surface of the target object, and the functional film is not strictly limited It is located on the outer side surface facing the acting part.

Wherein, there may be various specific ways to obtain the first resistance information of the functional thin film. The first functional film and the detection device for detecting the resistance information of the first functional film may be a part of the terminal device implementing the embodiments of the present application, or may be used as an external device of the terminal device. In this case, the detection The detection device for the resistance information of the first functional thin film can be transmitted to the terminal device through a specific information transmission method. The first resistance information may include resistance information of the functional thin film at a specific time, and may include resistance information of the functional thin film within a specific time period.

In the embodiment of the present application, since it is attached to the surface of the target object, the resistance value of the functional thin film changes with the change of the shape of the functional thin film. Therefore, the first resistance information may represent the shape of the surface of the target object Changes.

Step S102 , according to the first resistance information and the preset corresponding relationship between the resistance and the relative position, determine the first relative position information between the action part and the functional film.

In the embodiment of the present application, the preset corresponding relationship between the resistance and the relative position may be a linear relationship or a non-linear relationship, and the preset corresponding relationship may be based on the pre-collected resistance information of the functional film and the function The relative position information between the part and the functional film is determined through experiments and data modeling.

The specific form of the preset correspondence may be determined according to the specific representation of the relative position. In some embodiments, the relative position may be represented by a distance, and the preset corresponding relationship between the resistance and the relative position is represented by a preset resistance-distance mapping relationship. Of course, the relative position can also be represented by means such as coordinates, vectors, etc., then, the preset corresponding relationship can also be other mapping relationship.

In some embodiments, the preset corresponding relationship between the resistance and the relative position is represented by a preset resistance-distance mapping relationship.

The preset resistance-distance mapping relationship may be obtained by means of data modeling or the like according to the pre-collected resistance information of the functional thin film and the distance information between the acting part and the functional thin film. The resistance-distance mapping relationship may be a linear relationship or a nonlinear relationship, and the resistance-distance mapping relationship may be a discrete mapping or a continuous mapping. In addition, the resistance-distance mapping relationship may include multiple one-to-one mapping relationships consisting of a resistance value and a distance, or may include multiple one-to-one mapping relationships consisting of a set of resistance values and a set of distances. The specific type of the resistance-distance mapping relationship is not limited herein.

In some embodiments, the functional thin film includes at least two thin film blocks, each thin film block includes a thin film feature point, and the first resistance information includes the first resistance information corresponding to each thin film block in the functional thin film. a resistance value, the first relative position information includes the first distance between the action part and each feature point of the thin film, and the resistance-distance mapping relationship includes the mapping relationship between the resistance value set and the distance set, The number of elements contained in each of the resistance value sets and each of the distance sets respectively is the same as the number of the thin film blocks.

When the functional film is bent or twisted, the shape changes of different parts are different. Therefore, each first resistance value can represent the shape change of different film blocks on the functional film, which can be more accurate. Indicates the morphological change of the functional film. The position change of the acting part relative to the functional film can also be accurately captured and detected through each of the first distances. Therefore, the embodiment of the present application can more accurately detect the position change of the acting part Therefore, the stimulation accuracy of subsequent stimulation signals is improved.

In some embodiments, before step S202, it further includes:

Step S301, determining a plurality of sampling time nodes according to the posture of the target object;

Step S302, for each sampling time node, at the sampling time node, obtain an infrared image, and obtain second resistance information of the functional thin film, where the infrared image includes the action part and the functional thin film;

Step S303, obtaining a second distance between the acting part and the functional film from the infrared image;

Step S304 , establishing the resistance-distance mapping relationship according to the second distance and second resistance information corresponding to each sampling time node.

In the embodiment of the present application, multiple sampling time nodes are determined according to the posture of the target object, so that at different sampling time nodes, infrared images of the target object in different postures or motion states can be obtained, and the function The second resistance information of the film is used to determine the resistance change of the functional film of the target object in different postures or motion states, as well as the position change of the acting part.

In some embodiments, the infrared image may also be processed by image processing methods such as sharpness enhancement and binarization, so as to highlight the active part in the infrared image.

It can be understood that, the infrared image may include images obtained by photographing the acting part in different directions, so as to obtain the second distance between the acting part and the functional film from the infrared image.

The second distance between the action part and the functional film obtained from the infrared image may be determined according to the film setting method of the functional film.

For example, if the functional film includes at least two film blocks, the distance between the action portion and each film block can be obtained separately, or the feature points (such as the center point) on the action portion and each film block can be obtained separately. ), in this case, the number of the second distance may be more than one. Correspondingly, the second resistance information can also be determined according to the thin film arrangement of the functional thin film. For example, if the functional thin film includes at least two thin film blocks, the second resistance information can include the second resistance information of each thin film block. resistance value, the number of the second resistance values may be the same as the number of the second distances.

The embodiment of the present application is schematically described below with a specific example.

Illustratively, as shown in FIG. 4 , it is an exemplary plan view of a functional film attached to the user's neck skin. Wherein, it can be seen from the front view that the functional film includes 4 film blocks. It can be seen from the side view that the functional thin film is located on the surface of the target object, the acting part is located inside the target object, and the functional thin film and the acting part do not intersect.

For each sampling time node, at the sampling time node, the second resistance values R1 , R2 , R3 and R4 respectively corresponding to the four thin film blocks in the functional thin film can be obtained. In addition, an infrared image is acquired, and from the infrared image, the second distances D1 , D2 , D3 and D4 between the action part and the center point of each thin film block are respectively identified.

After obtaining the second resistance value (R1, R2, R3, R4) and the second distance (D1, D2, D3, D4) corresponding to each sampling time node, you can use (R1, R2, R3, R4) and (D1, D2, D3, D4) to establish a personalized database about the target object, and according to the personalized database, establish the resistance-distance mapping relationship by means of modeling and simulation.

In some embodiments, establishing the resistance-distance mapping relationship according to the second distance and second resistance information corresponding to each sampling time node includes:

generating a resistance change curve of the resistance value with time according to the second resistance information of each of the sampling time nodes, wherein the vertical axis of the resistance change curve represents time;

generating a distance variation curve of distance with time according to the second distance of each of the sampling time nodes, wherein the vertical axis of the distance variation curve represents time;

According to the resistance change curve and the distance change curve, the resistance-distance mapping relationship is obtained, wherein the resistance-distance mapping relationship is a continuous mapping relationship.

In the embodiment of the present application, a continuous resistance change curve may be obtained by fitting according to each discrete second resistance information, and a continuous distance change curve may be obtained by fitting according to each discrete second distance. In this case, the resistance The vertical axes of the variation curve and the distance variation curve are the same, so the resistance variation curve and the distance variation curve can be correlated according to the vertical axis, so as to obtain the resistance-distance mapping relationship. At this time, the obtained resistance-distance mapping relationship is a continuous mapping. Therefore, in applications, the first relative position information corresponding to the first resistance information can be directly obtained by querying the resistance-distance mapping relationship, which improves the processing efficiency.

Step S103 , according to the first relative position information, determine a signal generating parameter of the signal generator, where the signal generating parameter is used for the signal generator to generate a stimulation signal, and the stimulation signal is used for stimulating the action part.

In this embodiment of the present application, there may be various specific types of the signal generator. Exemplarily, the signal generator may be an ultrasonic transducer, and accordingly, the stimulation signal may be an ultrasonic signal; or, the signal generator may be an electrical stimulation instrument (such as an implanted electrode, etc.), correspondingly , the stimulation signal may be an electrical signal; or, the signal generator may also be a magnetic stimulation instrument, correspondingly, the stimulation signal may be a magnetic signal.

Exemplarily, the signal generation parameters may include the position information of the signal generator, the attitude information, the pulse setting information of the stimulation signal, and the settings of the signal generation components (such as array elements, electrodes, etc.) in the signal generator. at least one of the information. The signal generator may emit the stimulation signal according to the signal generation parameter.

In the embodiment of the present application, according to the first relative position information, there may be various specific manners for determining the signal generating parameters of the signal generator. For example, in the first relative position information, the current relative position between the functional film and the action part and the initial relative position between the functional film and the action part can be compared to determine Changes in the position of the acting part relative to the functional film. In addition, the first relative position information and the preset relative position between the signal generator and the acting part can also be compared to determine the positional deviation of the acting part, wherein the preset relative position The position may represent a predetermined relative position between the signal generator and the action part. After the positional deviation of the acting part is determined, the historical signal generation parameters when the signal generator and the acting part are in a preset relative position can be performed according to the positional deviation of the acting part. Adjust to obtain the current signal generation parameters. In addition, if the functional film is located on the signal generator, the first relative position information can be used to indicate the relative position between the signal generator and the functional film. For the first relative position, the signal generating parameters are determined, for example, the offset angle of the signal generator relative to the acting part is determined, and so on.

In the embodiment of the present application, the first resistance information of the functional thin film can be obtained, wherein the functional thin film is attached to the surface of the target object, the target object corresponding to the surface contains an action part, and the resistance value of the functional thin film varies with any Therefore, the first resistance information can represent the morphological change of the surface of the target object; then, according to the first resistance information and the preset between the resistance and the relative position Corresponding relationship, determine the first relative position information between the acting part and the functional film, in this case, the first relative position information can indicate that the position of the acting part changes after the shape of the surface of the target object changes Therefore, the signal generating parameters of the signal generator can be determined according to the first relative position information, so that the stimulation signal can accurately stimulate the acting part, and reduce the stimulation deviation caused by the position change of the acting part, Thus, the accuracy of stimulating the action part by the signal generator is improved.

In some embodiments, the surface of the target object is the neck skin of the target user, and the acting part is the vagus nerve of the target user's neck.

The human nervous system includes the central nervous system and the peripheral nervous system. The acting part is the 10th pair of the 12 pairs of cranial nerves in the human body, and it is a part of the peripheral nervous system. From the perspective of anatomical structure, the active part is emitted from the nucleus of the active part located in the posterior medial oblongata, passes through the jugular foramen to the neck, and then enters the chest and abdomen. Studies have found that stimulating the vagus nerve in the neck through electrical, magnetic, light and other physical stimulation methods can send electrical pulses to the brain, thereby achieving the effect of regulating the cranial nerves, and has great potential in the intervention of brain function diseases.

Therefore, the functional film can be attached to the user's neck skin and located outside the vagus nerve of the user's neck. At this time, the acquired first resistance information can represent the vagus nerve of the user's neck. morphological changes of the outer skin.

At this time, the first relative position information may be the relative position information between the vagus nerve and the functional membrane.

Wherein, since the vagus nerve is accompanied by human blood vessels, the position of the vagus nerve can be determined by detecting the position of the blood vessel close to the vagus nerve. Therefore, before establishing the resistance-distance mapping relationship, at each sampling time node, an infrared image including the vagus nerve and the functional thin film can be acquired. Because hemoglobin in blood absorbs more infrared rays than other tissues, it is possible to distinguish blood vessels from other tissues through infrared images, so as to determine the location of the corresponding blood vessels. In addition, the infrared image can be processed by image processing methods such as contrast enhancement, sharpness enhancement, binarization, etc., to highlight the color and shape of the blood vessels, and obtain the blood vessel distribution positions with clear boundaries. In some embodiments, the infrared image may be acquired by a near-infrared imaging method to improve the clarity of the blood vessels in the infrared image.

It can be seen that, in the embodiment of the present application, the first resistance information of the functional thin film can be obtained, and the first resistance information can represent the morphological change of the outer skin of the vagus nerve of the user's neck; then, according to the first resistance information, and the preset corresponding relationship between the resistance and the relative position, to determine the first relative position information between the vagus nerve and the functional film, at this time, the first relative position information can represent the morphological change of the outer skin of the vagus nerve Afterwards, the position change of the vagus nerve, therefore, the signal generation parameters can be determined according to the first relative position information, so as to reduce the stimulation deviation caused by the position change of the vagus nerve, thereby improving the signal generator to stimulate the vagus nerve. accuracy.

In some embodiments, the stimulation signal is an ultrasonic signal, and the signal generator is an ultrasonic transducer;

The step S103 may include:

determining the position of the ultrasonic transducer according to the first relative position information and the preset relative position between the signal generator and the action part;

Or, according to the first relative position information, determine the position of the triggered array element and/or the number of the triggered array element in the ultrasonic transducer, wherein the ultrasonic transducer includes at least two array elements, each of which is used to emit the ultrasonic signal.

At present, a large number of studies have confirmed that ultrasonic signals can effectively stimulate nerves, thereby achieving neural regulation. For example, in some application scenarios, an ultrasonic signal can be sent out through an ultrasonic transducer, and the ultrasonic signal can non-invasively penetrate human tissue and be focused at a certain depth in the human body, and the stimulation signal can cover the Action Department.

Wherein, the specific type of the ultrasonic transducer can be determined according to the actual application scenario. Exemplarily, the type of the ultrasonic transducer may be one of the following three types:

1. The ultrasonic transducer may be a patch type ultrasonic transducer.

Wherein, the patch-type ultrasonic transducer may include a plurality of array elements, and each array element is a unit capable of sending out ultrasonic signals. Generally, each array element is controlled by a corresponding independent data processing module, and each independent data processing module can be integrated in the same device or located in different devices.

The patch-type ultrasonic transducer may be marked with positioning mark points. After the patch-type ultrasonic transducer is attached to the surface of the target object, the calculation of the The relative position between the patch transducer and the acting part is used as the preset relative distance. After the first relative position information is acquired, it can be determined whether the position of the patch transducer has changed according to the first relative position information, so as to selectively excite different array elements to dynamically adjust the ultrasound The focal point of the signal to achieve accurate stimulation of the action part.

2. The ultrasonic transducer may be an ultrasonic transducer for the lying position.

In order to increase the comfort of the ultrasonic stimulation process, the target object may be stimulated when the target object is in a lying position.

For example, if the target object is a patient and the surface of the target object is the skin of the patient's neck, then after the patient is lying on the treatment bed, a U-shaped matching water bladder can be used on the patient's neck. Free movement of the head and neck. The ultrasonic transducer for the lying position is in contact with the neck skin after matching the water bladder. At this time, the ultrasonic signal is almost not attenuated.

The ultrasonic transducer for the lying position may also include a plurality of array elements. After the first relative position information is acquired, it can be determined whether the position of the patch transducer for the lying posture has changed according to the first relative position information, so as to selectively excite different array elements, To dynamically adjust the focus point of the ultrasonic signal, to achieve accurate stimulation of the action part.

3. The ultrasonic transducer may be a head-mounted ultrasonic transducer.

When the head-mounted ultrasonic transducer is used to perform the action part stimulation operation on the target object, the target object may be in a relatively fixed state, and the head-mounted ultrasonic transducer may, according to the control signal of its control unit, Adjustment is performed in at least one of the three dimensions of the up-down direction, the axial direction and the circumferential direction. After the first relative position information is acquired, it can be determined whether the position of the head-mounted ultrasonic transducer has changed according to the first relative position information, so as to adjust the position of the ultrasonic transducer to achieve Accurate stimulation of the active site.

In the embodiment of the present application, the acting part may be stimulated by using the ultrasonic signal generated by the ultrasonic transducer. In addition, when the target object is a human, the ultrasonic transducer can achieve non-invasive stimulation of the action part in the human body, and does not need to be implanted in the human body, reducing the damage to the human body, and at the same time, it is easy to adjust and the price is relatively reasonable. It can be seen that the use of ultrasonic transducers to stimulate the acting part has the advantages of being safe, non-invasive and easy to adjust.

In some embodiments, the step S103 includes:

Comparing, in the first relative position information, the current relative position between the functional film and the action part and the initial relative position between the functional film and the action part, to obtain a comparison result;

According to the comparison result, determine the offset of the position of the stimulation target on the acting part compared to the position of the preset target;

Based on the offset, signal generation parameters of the signal generator are determined.

In the embodiment of the present application, the comparison result can indicate the change of the position of the acting part relative to the functional film. Therefore, the stimulation on the acting part can be determined according to the deviation of the acting part The offset of the target position compared to the preset target position. For example, the position offset of the action part obtained in the comparison result can be used as the offset of the position of the stimulation target, or the comparison result can be compared according to the angular relationship in the actual space. The obtained positional shift amount of the action portion is converted to obtain the positional shift of the stimulation target.

The image data may include ultrasound images, magnetoencephalography (MEG), computed tomography (CT) images, magnetic resonance imaging (MRI) and magnetic resonance spectrum (MRS) ) at least one of them. Exemplarily, the signal generation parameters of the stimulation signal may include total stimulation duration, pulse stimulation time in one pulse period, intermittent time in one pulse period, pulse center frequency, pulse repetition frequency, pulse duration, and fundamental frequency. , the number of fundamental waves and the number of pulses. The value of each signal generation parameter can be determined according to information such as the disease type of the target object, the severity of the lesion, and the position depth (fat, muscle thickness) of the action part.
