摘要

A unique characteristic of piezoelectric materials is their ability of electric-mechanical transduction and converting mechanical energy to electrical energy or vice versa.This remarkable property,embedded in piezoelectric materials,has been exploited to construct a wide variety of acoustic transducers for industrial applications.These include acoustic experimental measurements [1-3],mobile and internet communications [4,5],intravascular ultrasound [6],medical imaging [7],rangefinders [8],fingerprint sensors,implantable micro-devices,nondestructive detection,measurement of the in-situ stresses of underground rock formation,and early warning systems for dam damage and natural hazards,among others.
