Abstract

This Small Business Technology Transfer (STTR)Phase I project will develop manufacturing, packaging and interface concepts for critical Structural Health Monitoring (SHM) components. The intention is to be able to cheaply manufacture robust actuator/sensors wafers, and isolate them from harsh operating environments including natural, mechanical, or electrical extremes. Currently the issues related to SHM system durability have remained unaddressed. In this project, microfabrication techniques will be developed to fabricate, assemble, wire and package the SHM system components for robust operation. In particular, in Phase I of this project, the piezoelectric actuators and sensor used for damage detection will be packaged, and then tested in hot and wet conditions. Research continued through a Phase II program would aim to package the other supporting components such as the battery and wireless chip, as well as integrating all of these components together for operation.
