[0015] A plurality of adjustment holes are evenly distributed on the adjustment disk.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, a smart wearable glove for monitoring joint movements using a flexible sensor comprises a palm end and a finger end, wherein the finger end comprises an outer layer, a conductive layer and an inner layer which are laminated in sequence, wherein the conductive layer comprises a front finger sleeve net, a middle finger cover net and a back finger sleeve net which are connected in sequence, wherein a plurality of front finger sleeve fibers which are staggered in a horizontal and vertical direction are distributed in the front finger sleeve net, a plurality of middle finger cover fibers which are staggered in a horizontal and vertical direction are distributed in the middle finger cover net, and a plurality of back finger sleeve fibers which are staggered in a horizontal and vertical direction are distributed in the back finger sleeve net. When used, the finger end is firstly put on the finger, and the palm end is put on the palm. At this time, the inner layer is connected to the outer surface of the finger. When the finger moves, the finger drives the inner layer to be pulled or contracted, and then the inner layer drives the front finger sleeve net, the middle finger cover net and the back finger sleeve net to be pulled or contracted. Therefore, the resistance on the front finger sleeve net, the middle finger cover net and the back finger sleeve net will change, and an electrical signal corresponding to the action is generated, thereby identifying the action. The advantages of the present invention also include: First point: When the fingers move, the front finger cover net, the middle finger cover net, and the back finger cover net are pulled or contracted to change the overall resistance, and then the electrical signals are used to monitor and identify the finger joint movements; Second point: The front finger cover net, the middle finger cover net, and the back finger cover net are all mesh fiber structures, which include multiple fibers, and the multiple fibers are connected horizontally and vertically. The mechanical strength of the fibers is high, so the structure is more stable and tougher, and there will be no cracks or delamination; Third point: The middle finger cover net covers the top of the knuckle to monitor and identify the movement of the knuckle without affecting the bending of the knuckle; the front finger cover net and the back finger cover net cover the knuckle to monitor and identify the pressure of the knuckle, which is used to assist in the monitoring and identification of the knuckle, thus improving the accuracy of identifying the movement of the finger joint; Therefore, the present invention has higher mechanical strength and greater stability.

[0017] 2. In the intelligent wearable glove for monitoring joint movements using a flexible sensor of the present invention, the front finger sleeve fibers include front transverse fibers, front vertical fibers and front gaps, the middle finger cover fibers include middle transverse fibers, middle vertical fibers and middle gaps, and the rear finger sleeve fibers include rear transverse fibers, rear vertical fibers and rear gaps. When used, the front transverse fibers and the front vertical fibers are fixed to each other to improve the stability of the structure, and the front gap provides the front transverse fibers and the front vertical fibers with space for movement when they are pulled to improve the accuracy of measurement. The middle transverse fibers and the middle vertical fibers are fixed to each other to improve the stability of the structure, and the middle gap provides the middle transverse fibers and the middle vertical fibers with space for movement when they are pulled to improve the accuracy of measurement. The rear transverse fibers and the rear vertical fibers are fixed to each other to improve the stability of the structure, and the rear gap provides the rear transverse fibers and the rear vertical fibers with space for movement when they are pulled to improve the accuracy of measurement. Therefore, the measurement accuracy of the present invention is relatively high.

[0018] 3. In the smart wearable glove for monitoring joint movements using a flexible sensor of the present invention, the front finger sleeve fiber, the middle finger cover fiber, and the back finger sleeve fiber are all made by centrifugal spinning. When used, the fiber generated by centrifugal spinning has strong toughness and is not easy to break, and the delamination phenomenon in the existing flexible sensor will not occur, so the present invention can be used stably for a long time. Therefore, the long-term stability of the present invention is good.

[0019] 4. In the intelligent wearable glove that uses a flexible sensor to monitor joint movements, the finger sleeve fiber, the middle finger cover fiber, and the back finger sleeve fiber are all made of a centrifugal spinning raw silk device, which includes a shell, a material chamber in the middle of the shell, a triangular cross-section of the material chamber, and a spinneret at the bottom of the shell. When used, the shell rotates along its axis, and at the same time, the centrifugal spinning solution in the material chamber moves toward the spinneret under the action of centrifugal force, and the centrifugal spinning solution is then ejected along the spinneret to form centrifugal spinning fibers, and then the centrifugal spinning fibers are subsequently processed to collect the centrifugal spinning fibers; the cross-section of the material chamber is triangular, which can ensure that the centrifugal spinning solution at the bottom of the material chamber is sufficient to ensure the mechanical strength of the centrifugal spinning fibers. Therefore, the centrifugal spinning effect of the present invention is better.

[0020] 5. In the smart wearable glove that uses a flexible sensor to monitor joint movements, the top of the centrifugal spinning fiber is flexibly connected to the middle of the feed barrel, and a plurality of feed holes are evenly distributed on the side of the feed barrel. When used, the shell rotates continuously, and the feed barrel does not rotate. Since the shell and the feed barrel are flexibly connected, the feed barrel will not hinder the rotation of the shell, and the feed barrel can replenish the material chamber while the shell rotates, so the spinning efficiency is relatively high; the feed hole is located on the side of the feed barrel, and the centrifugal spinning solution is guided to the direction of the spinneret. Therefore, the spinning efficiency of the present invention is relatively high.

[0021] 6. In the intelligent wearable glove for monitoring joint movements using flexible sensors of the present invention, a rotating column is inserted into the shell, and an adjustment disk is sleeved on one end of the rotating column located in the shell. The movement stroke of the adjustment disk is to move up and down along the rotating column. The side wall of the adjustment disk is an arc structure, and a plurality of adjustment holes are evenly distributed on the adjustment disk. When in use, when there is a lot of centrifugal spinning liquid in the material holding chamber, the adjustment disk floating on the surface of the centrifugal spinning liquid rises until the edge of the adjustment disk collides with the side of the material holding chamber. At this time, the centrifugal spinning liquid flowing out of the feed hole is located above the adjustment disk, and the centrifugal spinning liquid located at the bottom of the material holding chamber is sprayed out first, so the centrifugal spinning liquid can be prevented from being idle, thereby improving the utilization of the centrifugal spinning liquid. Efficiency; when there is less centrifugal spinning solution at the bottom of the feeding chamber, the adjustment plate floating on the surface of the centrifugal spinning solution drops down. At this time, a gap appears between the side wall of the adjustment plate and the feeding chamber, and the centrifugal spinning solution above the adjustment plate flows along the gap to the bottom of the feeding chamber, so the shortage of centrifugal spinning solution can be avoided; when the adjustment plate moves up and down, the centrifugal spinning solution is also stirred to make the centrifugal spinning solution more uniform; in very rare cases, the side wall of the adjustment plate will be stuck on the inner wall of the feeding chamber. At this time, the centrifugal spinning solution flows to the bottom of the feeding chamber through the adjustment hole. When there is more centrifugal spinning solution above the adjustment plate, the gravity of the centrifugal spinning solution will also cause the adjustment plate to drop, even if the side wall of the adjustment plate is disconnected from the inner wall of the feeding chamber. Therefore, the utilization efficiency of the centrifugal spinning solution in the present invention is relatively high. BRIEF DESCRIPTION OF THE DRAWINGS

Preferably, the conductive solute includes carbon black, metal powder, metal wire or carbon fiber, etc., and the polymer is a polymer commonly used in centrifugal spinning, such as PLA, PVA, PVP or PTFE, etc.

[0062] When applied, first select a conductive solute, such as carbon black, metal powder, metal wire or carbon fiber, and then make a polymer commonly used in centrifugal spinning, such as PLA, PVA, PVP or PTFE, and then mix the conductive solute with the polymer commonly used in centrifugal spinning evenly to obtain a centrifugal spinning solution, which is a hot molten body. The centrifugal spinning solution is then passed into the centrifugal spinning raw silk fiber 3 to make fibers, and then the fibers are subjected to relevant processing to obtain the front finger sleeve fiber 261, the middle finger cover fiber 241, and the back finger sleeve fiber 251.

[0063] Embodiment 4: The basic content is the same as that of Example 1, except that: See also Figure 1 — Fig.19 , the front finger sleeve fiber 261 is made of a centrifugal spinning raw silk device 3, the middle finger cover fiber 241 is made of a centrifugal spinning raw silk device 3, and the rear finger sleeve fiber 251 is made of a centrifugal spinning raw silk device 3; the centrifugal spinning raw silk device 3 includes a shell 31, the movement stroke of the shell 31 is to rotate along its axis, the middle part of the shell 31 is a material holding chamber 32, the cross section of the material holding chamber 32 is triangular, and a spinneret 33 is provided at the bottom of the shell 31, one end of the spinneret 33 is connected to one end of the material holding chamber 32, and the other end of the spinneret 33 is connected to the outside. Preferably, the number of the spinneret 33 is two, and the two spinneret 33 are symmetrically distributed along the axis of the shell 31.

[0064] When in use, the material chamber 32 contains centrifugal spinning liquid. Since the shell 31 rotates along its axis, the material chamber 32 also rotates along its axis. The centrifugal spinning liquid inside the material chamber 32 moves toward the spinneret hole 33 under the action of centrifugal force, and then the centrifugal spinning liquid is sprayed out along the spinneret hole 33 to form fibers. The cross-section of the material chamber 32 is triangular, so the centrifugal spinning liquid at the bottom of the material chamber 32 is abundant, so the quality of the sprayed fibers is better. The number and position of the spinneret holes 33 can be set as needed. In the present invention, the number of spinneret holes 33 is set to two, so the two spinneret holes 33 can spray fibers at the same time to improve the efficiency of fiber production.

[0065] Embodiment 5: The basic content is the same as that of Example 1, except that: See also Figure 1 — Fig. 20 A top hole 34 is provided on the top of the shell 31, and the top hole 34 is movably connected to the middle of the feed barrel 4. The feed barrel 4 is a cylinder, and the feed barrel 4 includes a feed side surface 41 and a feed bottom surface 42. A plurality of feed holes 43 are evenly distributed on one side of the feed side surface 41 close to the feed bottom surface 42.

[0066] When in use, the centrifugal spinning liquid is first introduced into the top of the feed barrel 4, and then moves toward the feed bottom surface 42, and then flows into the feed cavity 32 along the feed hole 43 on the feed side surface 41; the opening direction of the feed hole 43 is toward the spinneret hole 33, which guides the flow of the centrifugal spinning liquid to a certain extent; the middle part of the feed barrel 4 is movably connected with the top hole 34, so it will not affect the rotation effect of the shell 31, that is, the feed barrel 4 can be fed while the shell 31 is rotating.

[0067] Embodiment 6: The basic content is the same as that of Example 1, except that: See also Figure 1 — Fig. 22 The middle part of the rotating column 5 is inserted into the bottom of the housing 31. The end of the rotating column 5 located outside the bottom of the housing 31 is vertically connected to the middle part of the bottom gear 51. The outside of the bottom gear 51 is covered with one end of the conveyor belt 52, and the other end of the conveyor belt 52 is covered with the outside of the outer gear 53. The middle part of the adjustment disk 6 is covered on the end of the rotating column 5 located in the material storage chamber 32, and a limit block 54 is provided on the end of the rotating column 5 located above the adjustment disk 6; the edge of the adjustment disk 6 is a curved surface structure 61 protruding from top to bottom toward the housing 31, and the inner surface of the material storage chamber 32 is a curved surface type that is recessed from top to bottom toward the inside of the material storage chamber 32. A plurality of adjustment holes 62 are evenly distributed on the adjustment disk 6.

[0068] When in use, the outer gear 53 rotates to drive the conveyor belt 52 to rotate, and the conveyor belt 52 drives the bottom gear 51 to rotate, and then the bottom gear 51 drives the rotating column 5 to rotate, and then the rotating column 5 drives the shell 31 to rotate, so as to achieve the effect of the shell 31 rotating along its axis; when there is a lot of centrifugal spinning liquid in the material chamber 32, the adjustment plate 6 floating on the surface of the centrifugal spinning liquid moves upward, and when the arc surface structure 61 of the adjustment plate 6 conflicts with the side wall of the material chamber 32, the centrifugal spinning liquid flowing out of the feed hole 43 is located above the adjustment plate 6. At this time, the centrifugal spinning liquid located at the bottom of the material chamber 32 is sprayed out to prevent the centrifugal spinning liquid located at the bottom of the material chamber 32 from being idle; when the material chamber 32 is filled with a large amount of centrifugal spinning liquid, the adjustment plate 6 floating on the surface of the centrifugal spinning liquid moves upward, and when the arc surface structure 61 of the adjustment plate 6 conflicts with the side wall of the material chamber 32, the centrifugal spinning liquid flowing out of the feed hole 43 is located above the adjustment plate 6. At this time, the centrifugal spinning liquid located at the bottom of the material chamber 32 is sprayed out to prevent the centrifugal spinning liquid located at the bottom of the material chamber 32 from being idle; 2, when there is less centrifugal spinning solution in the container 32, the adjustment plate 6 floating on the surface of the centrifugal spinning solution descends, and a gap appears between the cambered surface structure 61 and the side wall of the container 32, and the centrifugal spinning solution above the adjustment plate 6 flows along the gap to the bottom of the container 32 to replenish the centrifugal spinning solution; if the cambered surface structure 61 is stuck on the side wall of the container 32, when there is enough centrifugal spinning solution above the adjustment plate 6, the gravity of the centrifugal spinning solution causes the adjustment plate 6 to descend, so the cambered surface structure 61 is disconnected from the side wall of the container 32; if the cambered surface structure is stuck on the side wall of the container 32, the centrifugal spinning solution can also flow into the container 32 through the adjustment hole 62 to replenish the centrifugal spinning solution in the container 32.

[0069] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed by the present invention should be included in the protection scope recorded in the claims.
