Summary:
The newly developed electrode for human body model, which is used for evaluation of EMI to a cardiac Active Implant Medical Device (AIMD), is reported. W. Irnich s human model is the most popular as a phantom used for evaluating external EMIs. However, it is difficult to compose two chambers electrically isolated each other in this model, because it is simply filled with saline water that has an equivalent electric conductivity to the human body. And also Irnich s model has no means to monitor output of AIMD, not to apply simulated cardiac signal to it. The newly developed electrode consists of applying and monitoring of signal portion and reduces crosstalk and signal leakage in application of cardiac pacing and sensing. We report here on the results obtained from our new improved electrode compare to current methods. The pacing output leakage reduced -6.8dB to -33.6dB and simulated cardiac signal leakage reduced -3dB to less than -60dB. It is practical and sufficient means of simulating EMI effects to an AIMD.
