Abstract: A physiological signal measurement system, a physiological signal measurement method, and a mobile device protective case are provided. The physiological signal measurement system includes a first electrode, a second electrode, a reference electrode, an impedance front-end circuit module and a dynamic signal matching module. The first electrode, the second electrode and the reference electrode are used to obtain a first sensing signal and a second sensing signal. The impedance front-end circuit module is used to detect a first impedance of the first electrode and a second impedance of the second electrode, and obtain an original differential signal according to the first sensing signal and the second sensing signal. The dynamic signal matching module is used to obtain a calibration sequence according to the first impedance, the second impedance and the original differential signal, and obtain a compensated calibration sequence according to the calibration sequence and the original differential signal.
