A wearable device includes a screen, a first electrode, a second electrode, and a circuit board. The screen and the second electrode are mounted on a housing. The first electrode is coupled to the screen and does not shield a display region of the screen, and the first electrode and the second electrode are electrically coupled by the circuit board. The first electrode has a first surface, the second electrode has a second surface, and the first surface and the second surface are configured to contact a human body of a wearer.

Wearable device

This application provides a wearable device. The wearable device includes a bearing body and a Bluetooth headset. An accommodating slot is disposed on the bearing body, a first locking component is disposed on the Bluetooth headset, and a second locking component is disposed on the bearing body. The Bluetooth headset is accommodated in the accommodating slot. The first locking component can be locked with the second locking component. The Bluetooth headset includes an operation portion. The operation portion is configured to: unlock the first locking component and the second locking component, and push the unlocked Bluetooth headset out of the accommodating slot. The wearable device in this application can directly accommodate the Bluetooth headset, to provide more convenience to a user.

A battery, a battery assembly, and a user equipment are disclosed. The battery includes a circuit board and a cell. The circuit board includes a first contact, a second contact, a third contact, a fourth contact, a battery management module, and a control switch. The first contact reports a capacity of the cell in the battery, or in the battery and a cascaded battery to an upper-level battery or an electricity load; the second contact receives and output the capacity of the cell in the cascaded battery; when the control switch is opened, the third contact is connected to the cell in the battery to charge or discharge the cell in the battery; when the control switch is closed, the fourth contact is connected to the third contact; and the battery management module triggers opening or closing of the control switch.
