Abstract

A system and method for monitoring erosion include a sensor (204) that is embedded in a substrate (202) having a first surface (206) that is subject to erosion and a second surface (208). The sensor (204) has a first mode in which the sensor (204) is responsive to RF interrogation (216) from a detector (212) and a second mode in which the sensor (204) is non-responsive to the RF interrogation. The sensor (204) transitions from the first mode to the second mode in response to being disabled due to contact with the erosive agent causing the erosion of the first surface (206). When the sensor (204) has transitioned to the second mode, this indicates that a predetermined level of erosion of the first surface (206) has occurred.
