Abstract
A single-arm two-electrode blood pressure measuring device and a measuring method thereof are provided. The single-arm two-electrode blood pressure measuring device includes two sensing electrodes, a photoplethysmogram (PPG) sensor, an analog signal processing unit, a filter and amplifier unit, an analog-to-digital conversion unit, and a digital signal processing unit. The single-arm two-electrode blood pressure measuring method includes: providing the two sensing electrode to sense an electrocardiography (ECG) signal of an user; providing the PPG sensor to sense a PPG signal; inverting a common mode signal between the two sensing electrodes and outputting to a filter of the analog signal processing unit by a differential amplifier; filtering and amplifying the ECG signal and the PPG signal by the filter and amplifier unit; and detecting multiple feature points of the ECG signal and the PPG signal to generate an estimated blood pressure value by the digital signal processing unit.
