[0002] The foot is an important weight-bearing organ and movement organ of the human body, and is involved in important functions such as human movement and support. Flat feet, high arches, and plantar fasciitis are common foot and ankle problems. Patients should go to medical institutions for clinical examination and diagnosis when necessary, and receive rehabilitation physiotherapy, orthotic insole treatment, etc. according to the situation. 3D printed customized orthotic insoles obtain foot surface data through a three-dimensional scanner, combine plantar dynamic and static pressure analysis and clinical diagnosis, and develop individualized, functional and comfortable orthotic insoles through computer software design; 3D printed insoles achieve better mechanical support through different area divisions, grids, and density optimization. The entire production process is simple, fast, clean, and hygienic, which is more in line with human characteristics and disease treatment needs;

The current 3D printed insoles lack monitoring of the patient's foot information, making it difficult for doctors and rehabilitation therapists to treat patients accurately and effectively. Therefore, the utility model proposes a 3D printed insole with foot monitoring function to solve the problems existing in the prior art. Utility Model Content

[0023] Embodiment 2

[0024] according to Figure 1 , 2 As shown in , 3 and 4, this embodiment proposes a 3D printed insole with a foot monitoring function, comprising an insole body 1 and a heel 2, wherein the heel 2 is arranged at the rear end of the bottom of the insole body 1, a first flexible pressure sensor 3 is arranged on the upper surface of the insole body 1, and the first flexible pressure sensor 3 is distributed in multiple groups, a second flexible pressure sensor 4 is arranged inside the heel 2, a posture sensor 5 is arranged at the middle position inside the insole body 1, and a microcontroller 6, a Bluetooth module 7 and a rechargeable battery 8 are arranged inside the insole body 1 at the rear end of the posture sensor 5;

[0025] The rechargeable battery 8 is used to power the first flexible pressure sensor 3, the second flexible pressure sensor 4, the posture sensor 5, the microcontroller 6 and the Bluetooth module 7. The signal output ends of the first flexible pressure sensor 3, the second flexible pressure sensor 4 and the posture sensor 5 are connected to the microcontroller 6 through wires, and the output end of the microcontroller 6 is connected to the Bluetooth module 7. The insole body 1 increases the thickness of the corresponding parts to ensure that the medial lateral arch, the lateral longitudinal arch, the transverse arch and the root bone are in the correct position. The first flexible pressure sensor 3, the second flexible pressure sensor 4 and the posture sensor 5 are added to measure the pressure, acceleration and angular velocity of the corresponding position. The measured data are collected and calculated by the microcontroller 6, and then the horizontal deflection angle of the corresponding position can be calculated and transmitted to the receiving device through the Bluetooth module 7, which is convenient for monitoring the patient's foot data and helps doctors and rehabilitation therapists to perform rehabilitation treatment on patients.

[0026] The insole body 1 is provided with an interlayer 9 inside, the posture sensor 5, microcontroller 6, Bluetooth module 7 and rechargeable battery 8 are arranged inside the interlayer 9, and a slit 10 is provided below the inside of the interlayer 9, and a plurality of slits 10 are provided corresponding to the posture sensor 5, microcontroller 6, Bluetooth module 7 and rechargeable battery 8, and the slits 10 pass through the bottom of the insole body 1.
