ABSTRACT:
A passive sensor that is located on or adjacent to a structure that can be used to monitor the affect of environment on a structure or coating that is used to protect the structure. The sensor includes a parasitic element that interacts with the environment and influences the intensity of the electromagnetic response between the inductive element of the sensor and the antenna of the interrogation reader device. The condition of the parasitic element is determined by the radio frequency interaction of the reader antenna and the inductive element of the sensor. The parasitic element condition correlates to the environmental severity, or corrosivity of the environment and damage to metallic structures or protective coatings. An integrated circuit within the sensor is capable of storing identification, time, material, and measurement information. The sensor and system of the present invention is useful for tracking and monitoring cumulate environmental damage to a structure.
