摘要：
This paper presents an approach for acousto-ultrasonic source localization based on metal core piezoelectric fiber (MPF) rosettes. MPF is a new type piezoelectric ceramic device with small size and high directivity to Lamb waves. The good directional properties of MPF are used to determine the direction of the acoustic waves by mounting three of the fibers in a rosette configuration in analogy with known electrical resistance strain gage rosette theory. The performance of the rosettes for source localization is validated on an aluminum plate.
