Patent ID: 7477060

Claim:
A detection system for monitoring a physical condition of an engineered structure, comprising: an array of sensors disposable in a predetermined pattern on the engineered structure and disposable between a surface of the engineered structure and a protective coating substantially covering said surface; and a data acquisition system in communication with the array of sensors for retrieving data from said sensors, the array of sensors providing data corresponding to at least one of a degree of cure of the protective coating and a corrosion rate of the engineered structure at each of the sensors, wherein at least one sensor of the array comprises: a sensing portion configured to detect at least one of an impedance, current, and voltage, said sensing portion disposed on a flexible substrate, and a control electronics portion including a unique address, wherein the sensing portion comprises a conductive element patterned as at least two electrodes on the flexible substrate, and wherein the control electronics portion includes voltage and current control electronics.
