Abstract: An electronic device includes a pressing component and a pressure sensor. The pressing component is disposed on a wearing structure of the electronic device. The pressing component includes an electromagnetic driving member and a pressure bearing member. The pressure sensor is disposed on the pressure bearing member, and the pressure sensor is located on a surface that is of the wearing structure and that faces a measurement body part of a user. The pressure bearing member is configured to be driven by the electromagnetic driving member to press the pressure sensor on the measurement body part, and the pressure sensor is configured to obtain a pulse wave signal of the measurement body part.
