[0002] Magnetic ionic liquid is a kind of magnetic functional ionic liquid composed of organic cations containing magnetic centers and inorganic or organic anions, that is, it has a single-electron organic free radical structure or a metal ion complex structure.

Detailed Description of the Embodiments

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] Referring to the attached Figures 1-3 As shown, a magnetic ionic gel sensor includes a detection component a1 and a detection component b2. The detection component a1 and the detection component b2 are connected by a connecting member 5. The detection component a1, the connecting member 5 and the detection component b2 are integrated into one body in a layered structure. The detection part a3 is arranged inside the detection component a1, and the detection part b4 is arranged inside the detection component b2;

[0028] Referring to the attached Figures 1-3 As shown, the detection part a3 is used to generate a first signal according to the magnetic field of the object to be measured and output it to the controller;

[0029] In this embodiment, the detection unit a3 is used to detect a magnetic field. When the detection unit a3 is in a magnetic field environment, the magnetic field environment will change the resistance of the detection unit a3. By the controller detecting the resistance change of the detection unit a3, the effect of detecting the magnitude of the magnetic field is achieved.

[0030] Refer to the appendix Figures 1-3 As shown, the detection unit b4 is used to generate a second signal according to the deformation of the object to be measured and output it to the controller;

[0031] In this embodiment, the detection unit b4 is used to detect mechanical deformation. Preferably, the detection unit b4 is used to detect the mechanical deformation of the object to be measured when it is bent. When the detection unit b4 undergoes mechanical deformation, the resistance of the detection unit b4 changes. By the controller detecting the resistance change of the detection unit b4, the effect of detecting the magnitude of the magnetic field is achieved.

[0032] The embodiment of the present invention is also implemented by the following technical solutions.

[0033] Refer to the appendix Figures 1-3 As shown, the detection unit a3 includes a capsule 31 and a magnetic ionic gel 32. The magnetic ionic gel 32 is disposed inside the capsule 31, and the lead a12 is electrically connected to the magnetic ionic gel 32.

[0034] It should be noted that the capsule 31 is made of an elastic material. In this embodiment, the material of the capsule 31 is defined as PDMS silicone rubber. The magnetic ionic gel 32 completely fills the inside of the capsule 31. The structures and sizes of the detection unit a3 and the detection unit b4 are exactly the same;

[0035] Another thing to note is that when the magnetic ionic gel 32 in the capsule 31 undergoes deformation, the resistance of the deformed magnetic ionic gel 32 inside the capsule 31 will also change. When the detection unit a3 is placed in a magnetic field, the magnetic ionic gel 32 inside the capsule 31 deforms under the action of the magnetic field, and the degree of deformation corresponds to the magnitude of the magnetic field. After the magnetic ionic gel 32 inside the capsule 31 deforms under the action of the magnetic field, the resistance of the deformed magnetic ionic gel 32 inside the capsule 31 also changes. Similarly, when the detection unit b4 deforms due to an external mechanical force, the resistance of the magnetic ionic gel 32 inside the capsule 31 of the detection unit b4 also changes. By the controller detecting the resistances of the detection unit a3 and the detection unit b4, the magnitudes of the magnetic field and the mechanical deformation can be obtained.

[0036] Refer to the appendix Figures 1-3As shown, in the embodiment of the present invention, the detection component a1 includes a base material a11, a lead a12, an electrode a13, and a container 14. The container 14 is arranged in the middle inside the base material a11. The electrodes a13 are embedded on both sides of the base material a11. A detection part a3 is arranged inside the container 14. One end of the lead a12 is electrically connected to the detection part a3, the other end of the lead a12 is electrically connected to the electrode a13, and the electrode a13 is electrically connected to the signal input end of the controller.

[0037] In this embodiment, the inside of the container 14 is set to a vacuum state. The material of the container 14 is nylon engineering plastic. The above settings are used to protect the detection part a3, to prevent the detection part a3 from deforming due to the deformation of the base material a11. At the same time, it is set to a vacuum state to prevent the air inside the container 14 from affecting the deformation of the detection part a3 under the action of the magnetic field, which is convenient for the detection part a3 to deform.

[0038] Refer to the appendix Figures 1-3 As shown, in the embodiment of the present invention, the detection component b2 includes a base material b21, a lead b22, an electrode b23, a magnetic isolation sleeve 24, and a connecting rod 25. The magnetic isolation sleeve 24 is arranged in the middle inside the base material b21. A detection part b4 is arranged inside the magnetic isolation sleeve 24 and is connected to the magnetic isolation sleeve 24 through the connecting rod 25. The electrodes b23 are embedded on both sides of the base material b21. One end of the lead b22 is electrically connected to the detection part b4, the other end of the lead b22 is electrically connected to the electrode b23, and the electrode b23 is electrically connected to the signal input end of the controller.

[0039] It should be noted that the number of the connecting rods 25 is several, preferably 36, and they are evenly distributed on the top and bottom of the detection part b4. The connecting rods are used to transfer the deformation of the base material b21 to the detection part b4 to drive the detection part b4 to deform when the base material b21 deforms. The magnetic isolation sleeve 24 is used to prevent the external magnetic field from affecting the detection part b4. In this embodiment, the material of the magnetic isolation sleeve 24 is defined as the flexible magnetic shielding material MS-F / FR. The magnetic isolation sleeve 24 wraps the detection part b4 inside, and the inside of the magnetic isolation sleeve 24 is a closed structure.

[0040] Refer to the appendix Figures 1-3 As shown, in the embodiment of the present invention, the connector 5 includes a base material c51. A convex part 52 is arranged at the bottom of the base material c51. The convex part 52 is connected to the base material b21, and the base material c51 is connected to the base material a11.

[0041] It should be noted that the substrate a11 is made of a hard material, preferably nylon engineering plastic, and the substrates b21 and c51 are made of soft materials, and the hardness of the substrate c51 is less than that of the substrate b21. Preferably, the materials of the substrates c51 and b21 are rubbers with different hardnesses, that is, rubbers with different softness degrees. There are gaps between the provided protrusions for enabling the substrate b21 to obtain a greater amount of deformation when the substrate b21 deforms.

[0042] Specific working principle: The side of the substrate b21 away from the substrate a11 is adhered to the surface of the object to be measured. When the object to be measured undergoes bending deformation, the substrate b21 deforms, and the connecting rod transfers the deformation of the substrate b21 to the detection part b4. The bladder 31 of the detection part b4 drives the magnetic ion coagulant inside to deform, causing a change in the resistance of the magnetic ion coagulant. The controller detects the change in the resistance value of the detection part b4 to obtain the magnitude of the mechanical deformation when the object to be measured undergoes bending deformation. When the object to be measured is in a magnetic field environment, the isolation sleeve is used to prevent the external magnetic field from affecting the detection part b4. In the magnetic field environment, for the detection part a3, the magnetic ion gel 32 in the bladder 31 deforms, and the resistance of the magnetic ion gel 32 that deforms inside the bladder 31 changes. The degree of deformation corresponds to the magnitude of the magnetic field. The magnitude of the magnetic field is detected by the controller detecting the change in the resistance of the detection part a3. By using the magnetic ion gel 32 to prepare the detection part a3 and the detection part b4, and simultaneously arranging the detection part a3 and the detection part b4 in the detection assembly a1 and the detection assembly b2 respectively, the controller detects the change in the resistivity of the detection part a3 and the detection part b4 to achieve the effect of simultaneously detecting the magnetic field and mechanical deformation, solving the problem that there is no sensor that can simultaneously detect the magnetic field and mechanical deformation prepared by the magnetic ion gel 32 in the prior art.

[0043] It should be noted that the specific model and specification of the controller need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0044] The power supply of the controller and its principle are clear to those skilled in the art and will not be elaborated here.

[0045] Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
