摘要：
A return electrode monitoring (“REM”) system is disclosed. The REM system includes a return electrode pad having a pair of split electrode pads and a detection circuit coupled to the pair of split electrode pads. The detection circuit and the pair of split electrode pads are adapted to resonate across a predetermined resonance range. The REM system also includes a controller coupled to the detection circuit and configured to provide a sweeping drive signal to the detection circuit across the resonance range. The detection circuit generates a drive signal in response to the sweeping drive signal and the controller determines a complex impedance across the at least one pair of split electrode pads as a function of the drive signal.
