    Abstract: A physiological detection device includes system including a first array PPG detector, a second array PPG detector, a display and a processing unit. The first array PPG detector is configured to generate a plurality of first PPG signals. The second array PPG detector is configured to generate a plurality of second PPG signals. The display is configured to show a detected result of the physiological detection system. The processing unit is configured to convert the plurality of first PPG signals and the plurality of second PPG signals to a first 3D energy distribution and a second 3D energy distribution, respectively, and control the display to show an alert message.

    Abstract: A microcirculation detection system including a heating device, a photosensitive array and a processing unit is provided. The heating device is used to heat a skin area. The photosensitive array is used to detect outgoing light from the skin area, and output a plurality of brightness variation signals respectively at different time points within a heating period. The processing unit is used to calculate a change of an array energy distribution varied within the heating period according to the plurality of brightness variation signals to accordingly identify a microcirculation state.

    Abstract: A method for establishing a personal blood pressure estimation model dedicated for a specific user includes: receiving a first reference measurement result of a reference sphygmomanometer; using a PPG sensor to measure a blood pressure of the specific user to generate a first PPG signal; calculating a first estimation result of the blood pressure of the specific user according to the first PPG signal; generating a first regulating parameter by comparing the first reference measurement result with the first estimation result; and establishing the personal blood pressure estimation model by using the first regulating parameter to adjust a set of parameter factor (s) of a basic blood pressure estimation model.
