wirelessly transmitted to a computer or other device alternatively the data may be outputted to a computer or other device in real time the coating monitor may have internal battery power or may obtain power via a lead other power sources such as solar cells vibration energy scavenging or the like may replace or supplement the battery additional sensors such as moisture or humidity sensors may be incorporated into the coating monitor fig3 shows one embodiment of a coating monitor 24 attached with a suction cup attachment 38 to a coated structure 40 clearly other attachment means could be used such as mechanical fastening means magnets adhesives or other means the coating 42 would typically be applied to the substrate 44 to prevent or reduce corrosion degradation or other deterioration the coating may include paints other polymeric films appliqu u00e9s or other peel and stick films ceramic coatings conversion coatings anodized films or other applied grown or deposited coatings the substrate could be any material that is electrically conductive for example metal carbon filled polymers metal filled polymers or any other electrically conductive material this substrate could be a component of almost any type of structure for example bridges airplanes ships ground vehicles tanks pipelines buildings towers supporting members or the like the substrate could also be laboratory test panels.
