[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] Example, see Figure 1-Figure 3 A device for measuring the circumference change of the ankle and instep position includes a sock 1 with two ends open, an ankle ring 2 is provided at the rear end of the upper end of the sock 1, and an instep ring 3 is provided at the lower end; flexible sensors 4 are provided on the inner sides of the ankle ring 2 and the instep ring 3; a microprocessor 5 is provided on one side of the outer side of the sock 1, and the flexible sensor 4 is electrically connected to the microprocessor 5 via a connecting line;

[0022] The microprocessor 5 is internally provided with a wireless communication module and a power supply module. The wireless communication module is used to transmit data to a mobile device or the cloud for real-time monitoring and data storage, and supports Bluetooth or Wi-Fi connection; the power supply module is used to provide the power required for the operation of the device and supports wireless charging or USB interface charging.

[0023] The flexible sensor 4 is a flexible ceramic sensor having microcracks in a conductive structure. When the shape and spacing of the microcracks in the conductive structure change, some or all of the microcracks in the conductive structure will be turned on and off. These changes will cause the electrical channel of the flexible sensor to change. The microcracks in the conductive structure change, for example, the length will elongate along the stretching direction and the width will decrease along the direction perpendicular to the stretching. According to the resistance formula R=ρL / S (where ρ represents the resistivity of the resistor and is determined by its own properties, L represents the length of the resistor, and S represents the cross-sectional area of ​​the resistor), the flexible sensor can be considered as a resistor that can change in the current loop. Then, by detecting whether its resistance value has changed, it can be inferred whether the user's ankle and instep have changed.

[0024] When the circumference of the ankle or instep increases, the microcracks in the flexible sensor's conductive structure are stretched, causing their length to increase and their cross-sectional area to decrease. This, in turn, increases the resistance due to tensile deformation. Conversely, when the circumference of the ankle or instep decreases, the degree of stretching of the flexible sensor decreases, and its resistance also decreases accordingly.

[0025] During specific testing, the flexible sensor collects data at intervals of one second to ensure real-time monitoring. The external side of the microprocessor 5 is equipped with a display screen 6, a data delete / remeasurement button 7, and a data record / upload button 8. After data processing and ratio calculation by the microprocessor 5, the data is displayed on the display screen 6.

[0026] The ankle ring 2 and the instep ring 3 are both made of elastic material and flexible silicone material to ensure comfortable wearing.

[0027] Working principle of this utility model:

[0028] Wear the sock 1 on your foot, insert your heel into the rear hole of the sock, and secure the entire sock so that the two flexible sensors 4 are located at the ankle and instep, respectively, ensuring close contact with the skin. The two flexible sensors 4 collect data on the circumference changes of the ankle and instep, respectively. The microprocessor 5 receives the sensor data, performs preliminary filtering and processing, and calculates the ratio of the ankle circumference to the instep circumference and displays it on the instrument panel. The data is then transmitted to a mobile device or the cloud via a wireless communication module. The data results are displayed on the app, and the user can choose to save, upload, or delete the data and re-measure at any time.

[0029] The utility model provides a device for measuring changes in the circumference of the ankle and instep. By using a flexible wearable sensor and a microprocessor, the circumference changes of the ankle and instep can be measured objectively and accurately, thereby achieving precise measurement of the lower limb dimensions of people with different heights, body shapes and weights and objectivity in data collection.

[0030] This utility model is designed as a wearable device, which is made of flexible elastic material and soft silicone material. Users can wear it continuously in daily life to maintain the comfort of detection and the possibility of continuous detection.

[0031] The utility model is easy to use. Data is transmitted to a mobile device through a wireless communication module. Data collectors can view real-time data and a summary of collected data at any time through a dedicated application. The ratio method is used to easily weaken the differences between groups, making it easier to further analyze and manage the data.

[0032] After the wearable device is fixed according to the heel position, the ankle and instep positions can be accurately located, thereby reducing errors in manually collected data and making the dimensional data more objective and accurate.
