Abstract:The thickness shear characteristics of the 2-2 piezo-composite materials are investigated experimentally. Presented qualitatively are the dependences of the features of the 2-2 composite on the volume fraction of pzt in the composite as well as on the resonant frequencies. Transverse wave transducers with high sensitivity and short pulse have been manufactined from the 2-2 composite materials.
Keywords:Piezo-composite material  2-2 Piezo-composite  Transverse wave transducer
