Abstract: An example wearable device includes a first housing, a second housing, a first electrocardiogramalectrode, a circuit board, and a temperature sensor. The first housing includes a first surface, a second surface. The circuit board is disposed with a contact. The first ECG electrode includes a first detection end, a second detection end, and a connection part. The first detection end is disposed on the first surface, the second detection end is disposed on the second surface. The second detection end is electrically connected to the contact and is in thermally conductive contact with the temperature sensor.

Abstract: An example crown assembly includes a button tube, a crown, a spring piece, a switch, and a fastening frame. The crown includes a crown cap and a crown stem that are connected. The spring piece includes a first plate, an elastic arm, and a second plate. Two ends of the elastic arm are connected to the first plate and the second plate. When pressure is exerted on the crown cap, the crown stem is capable of moving along the axis and pushing the first plate away from the end that is of the elastic arm and that is connected to the second plate, to enable the first plate to press the switch. The elastic arm is capable of generating elastic deformation, and when the pressure on the crown cap is released, the first plate is capable of pushing the crown stem away from the switch under elasticity of the elastic arm.
