MEMS Across the Valley of Death

Abstract

This paper elaborates increasing use of microelectromechanical systems (MEMS) in aerospace industry. MEMS are chip-size devices usually carved from semiconductor wafers. Jet engines running lean fuel mixtures are prone to instability. High-temperature MEMS sensors could improve performance and fuel mileage while reducing emissions. The paper also discusses different MEMS structures, as MEMS structures vary greatly. The oscillating proofmass structures sense angular rotation around an axis in the gyro on the right. The industry has also begun to build a more innovation-ready infrastructure. The MEMS and Nanotechnology Exchange provides another way to ease the tortuous path to commercialization. It promises more prototypes, and more technologies will flow from MEMS inventors in the future. However, experts believe that the real problem is that until more MEMS companies begin making money in aerospace, venture capitalists hesitate to fund their companies.
