  • Publication number: 20230076167
    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.

  • Publication number: 20230019122
    Abstract: An electronic device for measuring blood pressure includes a measurement assembly, an airbag, and a fluid pipeline, where a fluid pump and a pressure sensor in the measurement assembly are connected to the airbag through a first fluid pipeline and a second fluid pipeline respectively, a first nozzle in the first fluid pipeline and a second nozzle in the second fluid pipeline are located on a same side of the airbag, and an opening direction of one of the first nozzle and the second nozzle is away from that of the other, so that the first nozzle and the second nozzle are away from each other. This reduces impact on the pressure sensor caused by airflow in the airbag, and improves blood pressure measurement accuracy.
