Abstract
The problem addressed in this paper is the through-life, non-destructive monitoring of corrosion and disbonding damages in airframes. The concept presented here is to produce a MEMS smart sensor consisting of a number of small, independent, wireless sensors within the structure of the aircraft. The MEMS smart sensor can be installed during repair and in particular when the specific platform goes through a complete tear down during the Life Extension Program (LEP). The sensors are permanently installed and can be permanently monitored and contain bond degradation sensing elements and CMOS circuits. Each sensor has an independent address and can perform measurements and communicate over a true 2-wire bus to an external interface unit. US ( 09/501,798) and international (PCT/US00/03308) patent applications have been lodged for this technology.
