US Patent 7582359 - MEMS device for monitoring gas turbine

This patent from Siemens Energy teaches the advantages of MEMS devices for determining wear in gas turbine engines. Some relevant prior art which seems to have been overlooked is a report from the Institute for Defense Analysis entitled "MEMS in Turbine Engines" published in January 1999. Claim 1 reads:

1. A component for use in a combustion turbine, the component comprising:

a substrate;

a MEMS device affixed to the substrate; and

at least one connector in electrical communication with the MEMS device for routing a data signal from the MEMS device to a termination location.
