An electrode multiplexing physiological parameter monitoring ring, comprising a built-in power supply (2), a microprocessor module (1), an electrocardiogram monitoring analog front end (3), a skin conductance monitoring module (4), a first electrode (6), and a second electrode (7). The microprocessor module (1) is connected to the electrocardiogram monitoring analog front end (3) and the skin conductance monitoring module (4).
