Abstract
In various embodiments, the disclosed wireless sensors comprise chemically-sensitive conductor traces that respond to variations in the polymer surrounding the sensors due to the change in proximity of the chemicals stored within the polymer vessels (e.g., degradation of the structural integrity of the polymer vessel). The sensors may generally be installed at the interface between the corrosion barrier and the structural layers of a polymer vessel comprising any FRP, PTFE, plastic, or other polymers. As the chemical stored within the polymer vessel degrades or permeates the corrosion barrier, the impedance measured by the sensor, in one embodiment, changes, which signals a change in the structural integrity of the polymer in which the sensor is embedded.
