Abstract

Smart materials/structures have embedded sensors to monitor their own state. A novel sensor was synthesized by sputtering a piezoelectric film onto a metal fiber. The piezo-fiber sensor, similar in configuration to an optical fiber, is active since an electric field is developed when strained. Thus the sensor can detect vibration as well as fracture in a manner similar to acoustic emission. The sensor is well suited for use in fibrous composites, where it can be easily incorporated into filaments and strands.
