Abstract

We report results from a research program that investigates the feasibility of using optical fiber sensors to experimentally verify the performance of actuator elements attached to and embedded in prototype smart material systems, as well as to determine the nonlinear behavior of the actuator material response. The measurement of strain parallel to the long-axis of extrinsic Fabry-Perot interferometric (EFPI) fiber sensors is presented for three PZT/material configurations and one PMN configuration as a function of applied actuator excitation. These arrangements simulate the performance of an actuator by itself, in a stack, embedded in a surrounding material matrix, and attached to a supporting structural material. Experimental results are presented.
