A method for measuring a physiological signal includes following steps: detecting a first physiological signal of a target; receiving the first physiological signal to generate a first signal and a second signal by a radar sensor; selecting one of the first signal and the second signal to generate a plurality of original signals, which a phase difference is formed between the first signal and the second signal; and capturing a respiration signal and a heartbeat signal according to the plurality of original signals.

Method for measuring physiological signal and physiological signal measurement device

A phase shifter is provided, which includes a first substrate, a second substrate, a liquid crystal layer, a plurality of first ring-shaped electrodes and a plurality of second ring-shaped electrodes. The first substrate and the second substrate are disposed opposite to each other. The liquid crystal layer is disposed between the first substrate and the second substrate. The plurality of first ring-shaped electrodes are disposed sequentially and in interval on a side of the first substrate close to the liquid crystal layer. The plurality of second ring-shaped electrodes are disposed sequentially and in interval on a side of the second substrate close to the liquid crystal layer. A plurality of vertical projections, projected by the plurality of first ring-shaped electrodes to the second substrate, and at least partially overlapped with the plurality of second ring-shaped electrodes, respectively.
