In the following, the electrode is described in detail by taking an example of multiplexing the charging function and the body fat measurement function, in order to implement the body fat measurement function, 4 electrodes are generally needed, and in order to implement the charging function, 2 electrodes are needed, so in this embodiment, a total of 4 electrodes are provided, which are the first electrode 11, the second electrode 12, the third electrode 13 and the fourth electrode 14, the corresponding switch circuit has at least 4 signal input terminals, which are a1, a2, A3 and a4, respectively, the 4 signal input terminals are connected with the first electrode to the fourth electrode in a one-to-one correspondence, and at least 6 signal output terminals, which are B1, B2, C1, C2, C3 and C4, respectively, wherein B1 and B2 are charging terminals and are connected with a charging Chip Charger, C1 to C4 are body fat measurement terminals and are connected with a BIA Chip, and when the body fat detection function is implemented, the first electrode 11 to the fourth electrode 14 are needed, the switch circuit is controlled by the main control Chip to correspondingly connect 4 signal input ends A1-A4 with body fat measuring ends C1-C4 one by one, and further connect 4 electrodes with a body fat analysis Chip BIA Chip to realize the body fat collection and measurement, when the charging function needs to be executed, the third electrode 13 and the fourth electrode 14 need to be used, the switch circuit is controlled by the main control Chip to connect A3 and A4 with charging ends B1 and B2, and further connect the third electrode 13 and the fourth electrode 14 with a charging Chip, and the body fat detection function and the charging function cannot be executed simultaneously.

The switch circuit can be realized by adopting an analog switch chip, and can be controlled by the main control chip MCU to realize the gating of different input and output ends.

As a preferred scheme, the main control chip MCU has a voltage detection end, the voltage detection end is connected to the third electrode or the fourth electrode, and the main control chip generates the gating signal according to the voltage signal detected by the voltage detection end. The voltage detection end is connected with a specific electrode, when the charging function is executed, the specific electrode is connected with +5V of the charging seat, the voltage detection end is connected with the specific electrode, when the voltage detection end detects a high level, the intelligent wearable device is judged to be connected into the charging socket and needs to be charged, and therefore the gating of a charging function channel is executed. The intelligent wearable device of this embodiment is connected with charging socket's +5V fourth electrode 14 when charging, therefore, voltage detection end is connected with fourth electrode 14.

In order to enable the main control chip to detect a stable high signal during charging, the fourth electrode 14 is further connected to ground through a resistor R1.
