Paper Abstract

This paper reports the use of embedded extrinsic Fabry-Perot interferometric (EFPI) optical fiber sensors for the evaluation of composite materials containing arrays of piezoelectric actuator elements. The EFPI sensors are used in both differential and absolute measurement configurations. The extended 2D array of many small rod actuators is electrically driven through a pair of conductive electrode plates placed on top of and below the laminate. By applying an electrical potential difference between the plates, the actuator elements may be made to elongate axially. Two-dimensional spatial control of the resulting actuation function may be achieved by the interconnection of multiple conducting electrode addressing elements across the laminate.
