Distributed, Wireless MEMS Technology for Condition Based Maintenance

摘要

Distributed MEMS networks can revolutionize critical military, industrial, andcivil surveillance, transportation, manufacturing, and environmental management systems. Low cost sensor network development, coupled with the high performance of compact computing systems can provide new monitoring and control capability. Embedded microsensors and microactuators may provide control for improved dynamical response of large structures, for reduced requirements on dimensional precision, and for health monitoring and failure prediction of airframes, powerplants, buildings, and other structures. The installation of wireline networks for sensors raises important questions for condition based maintenance (CBM) system cost. For example, the installation of sensor network cables may require major modification to capitol equipment and vehicle systems, particularly for rotating component diagnostics. Thus, the development of autonomous, low power, wireless microsensors offers an opportunity to provide CBM at low cost to a wide range of applications. This presentation will describe fully integrated, wireless MEMS devices implemented with new RF communication and MEMS integration methods.
