Development of Fiber-PZT Array Sensor System

Abstract:

In this study, array type fiber-PZT senor systems were newly developed with capabilities of detecting both damage location and monitoring of gas or liquid leakage by applying time-frequency analyses. The system consists of two piezoelectric transducers for the signal receiver and generator applications and three optical fibers for wave propagation. The results showed developed fiber-PZT array sensor can accurately measure the position of crack and its intensity. Also the fluid leakage of methyl alcohol as test specimen, on the plate structure has also been investigated employing the fiber-PZT sensors. The ultrasonic wave optical fiber sensor can be used effectively to monitor changes in structural and chemical properties.
