[0026] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings. Obviously, the described embodiments are only a part instead of all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0027] The application scenarios described in the embodiments of the present application are used to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those of ordinary skill in the art can know that, with the emergence of new application scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems. In the description of the present application, unless otherwise specified, the meaning of "multiple" is two or more.

[0028] Figure 1 A structural schematic diagram of a monitoring device according to an embodiment of the present application, Figure 2 A sectional view of a tube according to an embodiment of the present application, with reference to Figure 1 and Figure 2The embodiment of the present application provides a self-powered monitoring device, which comprises a sensor 100 and a controller 200 electrically connected with the sensor 100; the sensor 100 comprises a detection ring 110 sleeved on a to-be-measured object 40, the detection ring 110 comprises a flexible pipe body 111 in a ring shape, the flexible pipe body 111 comprises a flexible shell 10 and a flexible conductor 20 arranged in the flexible shell 10, at least part of the flexible conductor 20 contacts the flexible pipe body 111; under the action of the expansion force of the to-be-measured object 40, the radial dimension of the flexible pipe body 111 changes and relatively moves with the flexible shell 10 to generate a friction-induced charge, and the controller 200 obtains the radial dimension of the to-be-measured object 40 according to current information converted by the induced charge.

[0029] In the present application, the number of detection rings is not limited, and the sensor comprises two or more detection rings. The more the number of detection rings is, the more the monitoring data is, and the higher the monitoring accuracy is, but the wearing comfort and the manufacturing cost increase.

[0030] When the number of detection rings is two, in use, along the axial direction of the to-be-measured object, one detection ring is sleeved on one end of the to-be-measured object, and the other detection ring is sleeved on the other end of the to-be-measured object. When the number of detection rings is multiple, in use, along the axial direction of the to-be-measured object, the multiple detection rings are distributed at intervals and are sequentially sleeved on the to-be-measured object.

[0031] It should be noted that the position of the detection ring is not limited in the present application. In actual monitoring, the position of the detection ring can be set according to the actual monitoring demand.

[0032] It can be understood that, in actual use, in order to further avoid the movement of the detection ring along the axial direction of the to-be-measured object, the detection ring can be fixed on the to-be-measured object, for example, fixed by an adhesive, and the auxiliary fixing mode is not limited in the present application.

[0033] In the present application, the radial dimension of the flexible pipe body of the detection ring is not limited. The smaller the radial dimension of the flexible pipe body is, that is, the thinner the flexible pipe body is, the stronger the extrusion of the flexible conductor is, that is, the greater the friction between the two is, the higher the strength of the induced current generated is, and the higher the monitoring accuracy is. Conversely, the greater the radial dimension of the flexible pipe body is, the weaker the extrusion of the flexible conductor by the flexible shell is, that is, the smaller the friction between the two is, the lower the strength of the induced current generated is, and the lower the monitoring accuracy is.

[0034] Similarly, this application does not limit the shape and size of the flexible conductor, as long as the flexible conductor and the flexible shell are in at least partial contact. When the radial dimension of the flexible conductor is larger, the squeezing effect on the flexible shell is stronger, that is, the friction between the two is greater, the intensity of the induced current generated is higher, and the monitoring accuracy is higher; conversely, the radial dimension of the flexible conductor is smaller, the friction between the two is smaller, the intensity of the induced current generated is lower, and the monitoring accuracy is lower.

[0035] Figure 3 This is a schematic diagram of the monitoring device according to another embodiment of this application, with reference to... Figure 3 Any two adjacent detection rings 110 are connected by a detection rod 120. The detection rod 120 includes a flexible shell 10 and a flexible conductor 20 disposed within the flexible shell 10. At least a portion of the flexible conductor 20 contacts the flexible shell 10. Under the action of the expansion force of the object under test 40, the radial dimension of the detection rod 120 changes, causing the flexible shell 10 and the flexible conductor 20 to move relative to each other to generate frictional induced charge. The controller 200 obtains the axial dimension of the object under test 40 based on the current information converted from the induced charge.

[0036] This application does not limit the connection method between the detection ring and the detection rod. They can be welded together or bonded together with an adhesive.

[0037] In this application, the radial dimension of the detection rod is not limited. The smaller the radial dimension of the detection rod, the stronger the squeezing effect of the flexible shell on the flexible conductor, that is, the greater the friction between the two, the higher the intensity of the induced current, and the higher the monitoring accuracy. Conversely, the larger the radial dimension of the detection rod, the weaker the squeezing effect of the flexible shell on the flexible conductor, that is, the smaller the friction between the two, the lower the intensity of the induced current, and the lower the monitoring accuracy.

[0038] It should be noted that, for the detection ring and the detection rod, in the initial state, the flexible shell and the flexible conductor are in at least partial contact, that is, they can be in partial or full contact.

[0039] In one optional embodiment of this application, Figure 4 is a state change diagram of the flexible shell and flexible conductor according to an embodiment of this application, referring to... Figure 4, the flexible shell 10 and the flexible conductor 20 are partially in contact in the initial state, when the radial dimension of the object to be measured 40 increases, the radial dimension of the flexible tube body 111 of the detection ring 110 or the detection rod 120 decreases, the contact area between the flexible shell 10 and the flexible conductor 20 increases, and a corresponding electrical signal is generated at the same time; when the radial dimension of the object to be measured 40 decreases, the radial dimension of the flexible tube body 111 of the detection ring 110 or the detection rod 120 increases, the contact area between the flexible shell 10 and the flexible conductor 20 decreases, and a corresponding electrical signal is generated at the same time.

[0040] In other embodiments of the present application, the flexible shell 10 and the flexible conductor 20 are fully in contact in the initial state, when the radial dimension of the object to be measured 40 increases, the detection ring 110 or the detection rod 120 is stretched, the inner surface area of the flexible shell 10 increases, the contact area between the flexible shell 10 and the flexible conductor 20 increases, and a corresponding electrical signal is generated at the same time; when the radial dimension of the object to be measured 40 decreases, the detection ring 110 or the detection rod 120 returns to the initial size or is compressed, the inner surface area of the flexible shell 10 decreases, the contact area between the flexible shell 10 and the flexible conductor 20 decreases, and a corresponding electrical signal is generated at the same time.

[0041] In summary, the size of the induced current generated by the monitoring device in the embodiments of the present application is linearly related to the contact area between the flexible shell and the flexible conductor, and the size of the pressure therebetween. The controller stores a preset program, which stores the data of current, pressure, contact area, and radial dimension or axial dimension of the object to be measured. When monitoring, the data of the object to be measured can be displayed in the controller by acquiring the current signal, which is convenient for viewing.

[0042] In the present application, the shape, size, and model of the controller are not limited as long as they meet the above requirements.

[0043] In the present application, the number of detection rings is not limited. Preferably, any two adjacent detection rings are connected by at least two detection rods. The more the number of detection rods, the more the monitoring data, and the higher the monitoring accuracy, but the wearing comfort and the manufacturing cost increase.

[0044] In some embodiments of the present application, the detection rods are evenly distributed along the circumference of the detection ring, so as to ensure that the detection ring is uniformly stressed and is not easy to be skewed.

[0045] In some embodiments of the present application, the inside of the flexible conductor 20 in any detection ring 110 and detection rod 120 is provided with a wire 300, and the wire 300 is electrically connected with the controller 200, so as to transmit the data monitored by each interval ring and detection rod 120 to the controller 200.

[0046] The material of the wire includes, but is not limited to, copper, aluminum, silver and other metals.

[0047] In some embodiments of the present application, the flexible conductor and the flexible shell have different electronegativities, and friction-induced charges are generated between the flexible conductor and the flexible shell when the flexible conductor and the flexible shell move relatively. The monitoring device in the present application only collects friction-induced charges generated between the flexible conductor and the flexible shell when the object to be measured deforms radially or axially, that is, by converting low-frequency mechanical energy into an electrical signal, so that the monitoring device can work all day and night with high endurance, and the working volume of the real-time self-powered monitoring device can be effectively reduced.

[0048] The materials of the flexible conductor and the flexible shell are not limited in the present application, as long as they are flexible materials, which can improve the wearing comfort of the monitoring device and ensure that the detection ring or detection rod deforms under the expansion force of the object to be measured.

[0049] The flexible conductor includes conductive gel or conductive rubber. Specifically, the conductive gel includes polyvinyl alcohol hydrogel, polyaniline-based hydrogel, polypyrrole-based hydrogel, etc.; and the conductive rubber includes conductive silicone rubber or other rubber doped with conductive fillers, etc.

[0050] The flexible shell includes silicone rubber, polybutadiene latex, styrene-butadiene latex or other flexible and stretchable materials.

[0051] It can be understood that the application field of the monitoring device is not limited in the present application, for example, it can be used for ED monitoring, and can also be applied to the detection of other objects to be measured for measuring radial or axial dimensions. When applied to ED detection, the detection ring of the monitoring device is sleeved on the penis, and the average number of night erections, erection time and erection length change data of three nights are monitored. The monitoring device is convenient to wear and use, and is convenient for users to self-monitor at home.

[0052] Based on the same inventive concept, Figure 5 FIG. 1 is a schematic diagram of a wearer wearing a monitoring device according to an embodiment of the present application, referring to Figure 5 The present application also provides a monitoring device including the monitoring device in various possible embodiments of the present application, and the monitoring device further includes a wearing body 30 connected with the controller 200, and the wearing body 30 is used to be fixed on a living body, for example, fixed on a human body.

[0053] The specific shape and size of the wearing body are not limited in the present application, and can be designed according to the type of the living body to be measured and the fixed position. The monitoring device worn on the human body is described below:

[0054] With reference to the foregoing Figure 3 and Figure 5 The wearing body 30 comprises an elastic waistband, which has an appearance similar to a common waistband. The controller 200 is arranged on the waistband. The elastic waistband can be fixed to the waist of the human body, thereby playing a role in fixing the monitoring device. The controller 200 and the waistband can be connected through a buckle connection, an adhesive connection, or a bandage connection, and the like.

[0055] The waistband is preferably made of a breathable and light material, such as a fiber waistband. Not only is the manufacturing cost low, but also the good breathability and light weight are conducive to improving the comfort of the user.

[0056] Of course, the wearing body can also be other types of wearable components, such as a bandage that can be fixed to the legs or arms of the human body, and the like.
