AN ELECTRODE MULTIPLEXING PHYSIOLOGICAL PARAMETER MONITORING RING 5 The invention an multiplexing parameter monitoring , a - in supply, microprocessor an electrocardiogram monitoring analog front end, a skin conductance monitoring module, a first and second microprocessor is to electrocardiogram monitoring front and skin monitoring 10 module. The first electrode and the second electrode are connected to the electrocardiogram monitoring front and electrocardiogram analog end processes electr ocardiogram signals collected by the first electrode and the second electrode. The first electrode and the second electrode are further connected to the skin conductance monitoring module, and the skin conductance monitoring module processes skin impedance 15 signals collected by the first electrode and the second electrode. A coupling manner in which the first electrode and the second electrode are coupled to the electrocardiogram monitoring analog front end is direct current coupling or alternating current c oupling, and is opposite to a coupling manner in which the first electrode and the second electrode are coupled to the conductance module. the invention, 20 monitoring, rate and conductance onitoring implemented through only two electrodes, so that the number of electrodes is reduced, and system design is simplified .
