Abstract
A physiological detection device includes an array sensor and a processing unit. The array sensor is configured to output array photoplethysmography (PPG) signals. The processing unit is configured to construct a 3D energy distribution, and identify an arc-like pattern in the 3D energy distribution according to the array PPG signals to accordingly identify different microcirculation states and an attaching status.
