Low Cost Corrosion/Corrosivity Sensor Systems For Ground Vehicles

This proposal develops an extremely low cost fiber grating corrosion sensor system that could be deployed on a vehicle. Costs are estimated to be approximately $0.25 per sensor in volume allowing hundreds to be deployed if necessary on difficult to access areas of a ground vehicle. In order to keep costs to an absolute minimum it is anitipated that the read out unit would be maintenance rather then vehicle based. The system has the ability to be deployed and operated over a very wide range of temperatures and offers inherent temperature compensation. Because it is passive and dielectrically based it has very long potential life, limited mainly by corrosion of the material it is measuring.
