Characterization of Piezoelectric Wafer Active Sensors [PDF]

open access: yesJournal of Intelligent Materials Systems and Structures, 2000
In the beginning, the classical one-dimensional analysis of piezoelectric active sensors is reviewed. The complete derivation for a free-free sensor is then extended to cover the cases of clamped and elastically constrained sensors. An analytical model based on structural vibration theory and theory of piezoelectricity was developed and used to ...

Corrosion damage detection with piezoelectric wafer active sensors [PDF]

open access: yesSPIE Proceedings, 2004
Since today's aging fleet is now intended to far exceed their proposed design life, monitoring the structural integrity of those aircraft has become a priority issue for today's Air Force. One of the most critical structural problems is corrosion. In fact the KC-135 now costs $1.2 billion a year to repair corrosion.
