Preferably, the mobile terminal 1 of the present embodiment further includes a memory for storing the measured fat data of the measured object.

In this embodiment, the measurement input component includes two sets of

electrode sheets

11, 12, and the two sets of

electrode sheets

11, 12 are respectively fixed to the outer surface of the terminal housing. Specifically, the terminal housing includes a frame, and the two sets of

electrode sheets

11 and 12 are respectively disposed on the frame of the terminal housing; since the user generally applies the terminal housing to the frame area of the mobile terminal 1 when the user holds the terminal housing, Fixing the two sets of electrode pads on the frame facilitates reliable contact between the human hand and the electrode pads.

Further, the frame of the terminal housing includes a long side frame 13 and a short side frame 14; therefore, preferably, one of the two sets of electrode sheets 11 is fixed to the long side frame 13 and the other set 12 is fixed to the short side frame 14 . That is, the user can hold one hand to contact one of the electrode pads 11 with one hand, and the other hand is used to contact the other set of electrode pads 12; thus, one set of electrodes is excited by one hand output. The current is supplied to the human body, and the other set of electrodes receives the excitation current flowing through the body through the other hand. Therefore, the two sets of electrode sheets are respectively disposed on the long side frame and the short side frame, which is more in line with the user's holding habit (generally, one hand is held in the long side frame area).

Each of the electrode sheets includes at least one electrode sheet (as long as it is a conductor). In fact, the more the number of electrode sheets included in each group of electrode sheets, the higher the accuracy of measurement. In this embodiment, considering the area of the outer surface of the terminal housing and the measurement effect, each set of electrode sheets is set to include two electrode sheets; that is, two

electrode sheets

The terminal housing actually includes a back cover (for example, a battery cover). In other embodiments, any one of the electrode sheets or the two sets of electrode sheets may be disposed on the back cover; or the terminal housing actually includes the inner cover. The housing (for example, the rear case of the mobile phone), any set of electrode sheets or two sets of electrode sheets may also be disposed on the inner casing (in this case, the back cover needs to be opened for measurement); the above is merely an example.

In the present embodiment, the impedance measuring circuit is used to measure impedance data of a human body. The impedance measuring circuit comprises an excitation current source, a voltage measuring unit and an arithmetic unit; the excitation current source is connected to one of the electrode sheets (output excitation current), and the voltage measuring unit is connected to the other group of electrode sheets (receiving the excitation current through the human body); The arithmetic unit is connected to the voltage measuring unit. However, the present embodiment is not limited to the specific form of the impedance measuring circuit. The above is merely an example.

For example, the two

electrode sheets

11a, 11b of one set of the electrode sheets 11 are connected in parallel to the excitation current source (ie, the excitation currents outputted by the two

electrode sheets

11a, 11b are completely independent), and the two electrode sheets 12a of the other set of the electrode sheets 12 are 12b is connected in parallel to the voltage measuring unit (ie, the excitation currents received by the two

electrode sheets

12a, 12b are completely independent). At this time, the two pairs of input-output electrodes may be the electrode sheet 11a and the electrode sheet 12a, the electrode sheet 11b and the electrode sheet 12b; or, the two pairs of input-output electrodes may be the electrode sheet 11a and the electrode sheet 12b, the electrode sheet 11b and the electrode Sheet 12a. By analogy, when each set of electrode sheets contains three or more electrode sheets, three or more pairs of input-output electrodes can be formed. Therefore, every The more the number of electrode sheets included in the electrode sheet, the more the number of pairs of input-output electrodes formed, the more accurate the measurement. The above is only an example. In essence, the two

electrode sheets

11a and 11b of one set of the electrode sheets 11 may be connected in parallel to the voltage measuring unit, and the two

electrode sheets

At the time of measurement, one hand of the user holds the mobile terminal 1 to contact one of the electrode sheets 11 and the other hand contacts the other set of electrode sheets 12. The excitation current source outputs the excitation current to the human body through a set of electrode sheets; the voltage measurement unit receives the excitation current after passing through the human body through another set of electrode sheets, and calculates the excitation current generated in the human body according to the received excitation current after passing through the human body. Voltage drop; the arithmetic unit calculates the impedance data of the human body based on the voltage drop. Then, the processor generates fat data of the measured object based on the impedance data. Wherein, the fat data includes at least the fat content, but is not limited thereto, and a person skilled in the art can set a calculation manner according to actual needs to generate other measurement parameters such as bone density.
