The electronic device 100 may also process the third digital signal to obtain data reflecting the body fat information of the user, and the data is displayed on the display screen 50.

Through setting up pressure sensor 25, electronic equipment 100 detectable user's weight information, electronic equipment 100's function is abundanter, more can satisfy user's demand, helps promoting user's use experience. The process of detection by the pressure sensor 25 and the process of detection by the array-type pressure sensor 21 do not interfere with each other and can be performed simultaneously.

The communication module 40 may be in signal connection with the conversion circuit 354, and may transmit the weight data output by the conversion circuit 354 to the terminal device, and the terminal device may display the weight data of the user after receiving the weight data. The terminal device can store the weight data after receiving the weight data each time. The user can know the change trend of the weight data of the user in a period of time according to the data stored in the terminal equipment, and the health problem can be found more favorably by the user.

According to the electronic device 100 provided by the embodiment of the application, the detection module comprises the array type pressure sensor 21, the heart rate detection module 23, the detection electrode 24 and the pressure sensor 25, the electronic device 100 can simultaneously detect the distribution information of the pressure applied to the electronic device by the sole of a user, the heart rate information of the user, the body fat information of the user and the weight information of the user, the functions of the electronic device 100 are diversified, and the requirements of the user can be met; and the detection of the four kinds of information can be carried out simultaneously, which is beneficial to improving the use experience of the user. The texture detection module 22 of the electronic device 100 may detect the texture information of the user, so as to identify the user according to the texture information of the user, thereby facilitating the tracking and recording of the health data of the same user.

In one embodiment, the terminal device may download an app that may manage user health data. When the user is judged to be the target user according to the texture information of the user, the terminal device can automatically log in the app without other operations of the user, and the user experience is better. And when the user is judged not to be the target user, the terminal equipment does not log in the app, so that information leakage of the user can be avoided.

The app can convert the first digital signal received by the terminal device into distribution information of the pressure applied by the user to the electronic device, and store the distribution information; the second digital signal received by the terminal equipment can be converted into data reflecting the heart rate information of the user and stored; the third digital signal received by the terminal equipment can be converted into data reflecting the body fat information of the user and stored; the data reflecting the weight information of the user received by the terminal equipment can be stored. These stored data, collectively referred to as health data, can be monitored for long-term health data by the app. The app can also perform real-time analysis according to the health data of the user, and can remind the user in time if the health problem possibly exists in the user is analyzed. When the user is a patient or an old person in the chronic disease rehabilitation treatment, the terminal device can also send the data obtained by the app to the guardian or the doctor terminal device of the user, so that the guardian or the doctor of the user can check the health data of the user, and useful information is provided for remote medical treatment.
