A new inductive coupling based wireless system is being developed to monitor the condition status of aortic stent-grafts. It relies on the measure of the stent-graft's outer pressure using a capacitive sensor placed in a LC resonant circuit. The work presented herein addresses the testing of the LC sensor circuit to diagnose whether observed pressure deviations are due to defects occurring in the sensor's inductor and capacitor or to an actual degradation of the stent-graft.
