[0028] The present application is further described in detail below with reference to the accompanying drawings.
[0029] See also Figure 1-5 As shown, a precise positioning flexible sensing component is shown, which includes an insulating flexible body 1 and a sensing unit arranged in the insulating flexible body 1.
[0030] In this embodiment, the insulating flexible body 1 can be made of materials such as textile fabrics and woven fabrics; the sensing module 21 can select the corresponding sensor according to the specific detection needs, preferably an electret sensor, which has the characteristics of flexibility, high sensitivity, and ultra-thinness. At the same time, it is a force-electric coupling sensor and carries its own charge, and no external power supply is required, so that the insulating flexible body 1 provided with the electret sensor can be washed; the sensing module 21 can be fixed on the insulating flexible body 1 by bonding, sewing and other processes, and the signal line 22 and the ground line 23 are woven into the insulating flexible body 1, combined with Figure 2-3 As shown, there are two insulating flexible bodies 1 , which are stacked and arranged, and the sensing unit is accommodated between the two insulating flexible bodies 1 .
[0031] When in use, the insulating flexible body 1 is processed into products such as a seat cushion and a mattress, so that the person being tested can complete body monitoring while sitting or lying down, further improving the testing comfort of the person being tested.
[0032] In this embodiment, combined with Figure 4-5 As shown, the sensing unit includes multiple sensing sections 2 arranged along the width of the insulating flexible body 1. Each sensing section 2 includes two sensing modules arranged along the width of the insulating flexible body 1. Each sensing module includes multiple sensing modules 21, multiple signal lines 22, and multiple ground lines 23. The multiple sensing modules 21 are spaced apart along the length of the insulating flexible body 1. The multiple signal lines 22 of the multiple sensing modules are connected in parallel. The multiple sensing modules can independently output parameters to prevent damage to one sensing module from affecting the detection of other sensing modules.
[0033] Specifically, the sensing unit includes a plurality of sensing modules 21 arranged in a rectangular array, each sensing module 21 is provided with a signal line 22 and a ground line 23, and the plurality of signal lines 22 and the plurality of ground lines 23 are respectively accommodated in the insulating flexible body 1, and the signal lines 22 and the ground lines 23 are not conductive to each other.
[0034] In this way, the sensor modules 21 arranged in a rectangular array can accurately locate the monitored parts, thereby improving the monitoring accuracy; at the same time, the insulating flexible body 1 can be directly supported on the body parts of the monitored person and accurately monitor the corresponding body parts through the sensor modules 21, without the need to connect a large number of wires to the body, which not only improves the monitoring efficiency but also improves the monitoring comfort of the monitored person; and, the signal line 22 and the ground line 23 are both accommodated in the insulating flexible body 1, which effectively avoids the signal line 22 and the ground line 23 from being entangled with each other and breaking.
[0035] When the body parts of the person being tested are supported on the insulating flexible body 1, the multiple sensing parts 2 can independently perform multiple parameter detection on different body parts of the person being tested, greatly improving the detection efficiency; at the same time, the signal lines 22 connected in parallel can independently output parameters to the outside, avoiding the impact of damage to one of the sensor modules 21 on the detection of other sensor modules 21.
[0036] In this embodiment, there are at least two sensor modules, with a first gap 3 defined between any two adjacent sensor modules. Multiple signal lines 22 are arranged in the first gap 3. The multiple signal lines 22 of two adjacent sensor modules are arranged in pairs, and the two corresponding signal lines 22 are symmetrically arranged about the center line of the first gap 3. The first gap 3 provides ample space for the multiple signal lines 22, effectively preventing the multiple signal lines 22 from crossing or entangled during arrangement, thereby improving the detection accuracy of the sensor module 21.
[0037] Among them, the ends of the multiple signal lines 22 away from the sensor module 21 have output ends, and the multiple output ends of the multiple signal lines 22 are combined to form an output part 4, which is connected to the sensor receiving system to output detection signals.
[0038] In this embodiment, the multiple ground wires 23 constituting the sensor modules are connected in series to form a ground wire group. The multiple ground wire groups constituting the multiple sensor modules are connected in series, and a second gap 5 is defined between each pair of adjacent sensor modules 21. The multiple ground wires 23 are arranged in the multiple second gaps 5. The second gaps 5 provide ample space for the multiple ground wires 23, effectively preventing the multiple ground wires 23 from crossing or entangled during arrangement, thereby improving the grounding effect of the sensor modules 21. The second gaps 5 further prevent the multiple ground wires 23 from crossing or entangled during arrangement.
[0039] Among them, one end of the multiple ground wires 23 away from the sensor module 21 has a grounding end, and the multiple grounding ends of the multiple ground wires 23 are connected to form a grounding portion 6, which is used for grounding to prevent electric shock accidents.
[0040] In this embodiment, the insulating flexible body 1 includes two insulating layers stacked together, with the sensing unit housed between them. Each insulating layer is formed from a textile, woven fabric, or a layer of insulating adhesive. The two insulating layers encase the sensing unit from both sides, preventing damage to the sensing unit from continuous exposure to the outside world and further enhancing the comfort of the subject.
[0041] In this embodiment, the signal line 22 and the ground line 23 have at least one of a zigzag, serpentine, and sinusoidal structures. The shapes and structures of the signal line 22 and the ground line 23 ensure that the entire system has good stretchability and that the connected sensors function properly, thereby maximizing the performance and accuracy of the sensors.
[0042] In this embodiment, the sensing module 21 includes at least one of pressure, temperature, stress, light, electricity, magnetism, sound, and electrochemical sensors. The use of multiple types of sensors can enable the detection array to have the ability to obtain multiple external sensing information, and have more powerful functions and performance. During implementation, the sensing module 21 is preferably a flexible stretchable sensor. The stretchable part of the flexible stretchable sensor can be physically stretched, and the non-stretchable part does not have structural stretchability, so its position can change but the structure remains unchanged. In this way, the signal line 22 and the ground line 23 located thereon can also be physically stretched, thereby protecting the sensing module from the influence of stretching to the greatest extent, and being able to perform normal functions and ensure its good electrical performance.
[0043] The precise positioning flexible sensing component is flexible and bendable as a whole, and can be adaptively attached to different parts of the human body with a small attachment gap, so that the monitoring part can be precisely positioned, thereby improving the monitoring accuracy.
[0044] In summary, this application includes at least one of the following beneficial technical effects:
[0045] 1. By providing a sensing unit including a plurality of sensing parts arranged along the width direction of the insulating flexible body, each sensing part includes a plurality of sensing modules, the monitoring part can be accurately positioned, thereby improving the monitoring accuracy;
[0046] 2. The insulated flexible body can be directly supported on the monitored body parts and accurately monitor the corresponding body parts through the sensor module, eliminating the need for connecting a large number of wires to the body. This not only improves monitoring efficiency but also enhances the monitoring comfort of the monitored person.
[0047] 3. The signal line and the ground line are both contained in the insulating flexible body, which effectively prevents the signal line and the ground line from being entangled with each other and breaking.
[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
