Abstract

Smart materials/structures have embedded sensors to monitor theirown state. A novel sensor was synthesized by sputtering a piezoelectric film ontoa 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 candetect vibration as well as fracture in a manner similar to acoustic emission. Thesensor is well suited for use in fibrous composites, where it can be easilyincorporated into filaments and strands.
