Assessing the operational state of engineering systems and health monitoring of vital engineering components
in-situ and in real-time is a important capability that is required for modern engineering designs to be fully utilized. Such active monitoring can minimize maintenance costs, provide real-time system status, and allow for scheduling of major repairs at opportune times. In particular, sensors and sensor systems that are seamlessly integrated into the structural and functional components, and are capable of withstanding
harsh environments, will be the key to the successful implementation of actively monitored system components.
Central to this task is the fact that these state awareness sensors must—ideally—not disturb or alter any aspect of the system it is interrogating. After-market sensors, even if attached during the manufacturing process, can be unreliable, difficult to install, and may adversely affect component operation. A sensor that is directly embedded into the component (written on the structure itself), in a coordinated manner has substantial advantages in terms of reliability, longevity, and minimal disturbance of component function. Coatings provide an ideal platform for integration of such sensors with structures.
This presentation will focus on the integration of sensors into thermal spray coatings using a newly developed methodolodgy. Sensors for physical phenomena including temperature, heat flux, strain, humidity, magnetics have been successfully demonstrated. In addition, it is possible to incorporate thick film electronics through patterning and multilayering strategy. This presentation will provide a description of the capability and salient results
