DETECTING SYSTEM AND MOBILE ELECTRONIC APPARATUS, AND METHOD FOR DETECTING PHYSIOLOGICAL CHARACTERISTIC THEREOF METHOD THEREOF

摘要

A detecting system, a mobile electronic apparatus and a method for detecting a physiological characteristic thereof are provided. The mobile electronic apparatus includes a sensor unit, a PPG photoplethysmography (PPG) sensor, and a processing unit. The sensor unit has a first, second, and third sensing electrodes. The PPG sensor senses a PPG signal. The processing unit is coupled to the sensor unit and the PPG sensor. When the first and second sensing electrodes detect a voltage difference above a threshold, the PPG sensor is triggered to detect blood volume changes, and when the third sensing electrode is triggered to detect electrical activity of a heart between the first and third sensing electrodes, the PPG sensor is disabled by the processing unit.
