Title:
PRESSURE MEASUREMENT APPARATUS, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/088113
Kind Code:
A1
Abstract:
A pressure measurement apparatus, and an electronic device, which relate to the technical field of exercise health, and are used for providing an electronic device which can accurately measuring external applied pressure. The pressure measurement apparatus comprises an elastic sheet and one or more electromechanical conversion modules. The elastic sheet has a first surface for receiving an external force, and the elastic sheet is used for deforming under the action of the external force. The elastic sheet serves as an external force receiving structure and transmits the external force in a deformed manner. The electromechanical conversion module is arranged on the side of the elastic sheet that faces away from the first surface, and the electromechanical conversion module is used for converting the external force borne by the elastic sheet into an electric signal according to the deformation of the elastic sheet. The pressure measurement apparatus can be applied to a wearable device, such as a wristwatch and a bracelet. Compared with obtaining HRV information by means of monitoring PPG signals by using an optical sensor, using the present pressure measurement apparatus to perform measurement on a skin artery has a relatively strong capability for resisting a movement interference, and an obtained pressure pulse wave signal is more accurate.
