The investigation of local piezoelectric properties of piezoelectric transducers by acoustic microscopy

Local piezoelectric properties of film and plate piezoelectric transducers have been studied by transmission acoustic microscopy methods at a frequency of 450 MHz with a resolution of 3 mu m. One-dimensional profiles and gray-scale acoustic images of the microstructure have been obtained. It is concluded that acoustic microscopy can be used effectively for the investigation of the nonmechanical characteristics of piezoelectric transducer specimens.<
