MEMS is the word for jet engines

摘要

Researchers at Purdue University have developed microelec-tromechanical systems (MEMS) that can survive the harsh conditions inside jet engines to detect impending temperature-induced bearing failure significantly earlier than conventional sensors. The new sensors directly monitor the temperature of engine bearings, whereas conventional sensors work indirectly by monitoring the temperature of engine oil, yielding less specific data. Advance warning is critical so that an engine can be shut down before it fails.
