METHOD FOR COLLECTING PERSONAL HEALTH DATA AND PERSONAL HEALTH DEVICE UTILIZING THE SAME

摘要

A personal health device includes multiple photoplethysmogram (PPG) sensors, multiple electrodes and a processing circuit. The PPG sensors are configured for sensing multiple PPG signals. The electrodes are configured for sensing multiple skin voltages. The processing circuit is coupled to the PPG sensors and the electrodes and configured for estimating an ankle brachial pressure index (ABI) according to the PPG signals and the skin voltages.
