Abstract (en)
[origin: WO2023031906A1] Systems and methods for optimizing sensor pressure in blood pressure (BP) measurements using a wearable device are provided. An example method includes recording photoplethysmogram (PPG) data using a PPG sensor of a wearable device while a pressure applied by the PPG sensor to a blood artery of a user is gradually increasing, monitoring a pulsating parameter associated with the PPG data, determining that the pulsating parameter has passed a critical value, in response to the determination, causing the increase of the pressure to stop, recording further PPG data using the PPG sensor and electrocardiogram (ECG) data using input plates of the wearable device, analyzing the further PPG data and the ECG data to determine a pulse transit time (PTT), a pulse rate (PR), and a diameter parameter, and determining, using a pre-defined model, a BP based on the PTT, the PR, and the diameter parameter.
