Functionally graded piezoelectric material and related functionally graded piezoelectric bending drive

However, in practice the process of preparing the drive, a continuous distribution of the material component is difficult, replaced by a multilayer structure. In this paper, tape casting process to prepare a series of functionally graded  electric meter  material and related  Voltage stabilizer graded piezoelectric bending drive. The main contents include: the use of conventional solid phase synthesis method to prepare based piezoelectric ceramic powders; right PNN-PZT-based  circuit breakers ceramic powder slurry was cast performance studies; tape casting process used to prepare a series of casting sheet; Preparation piezoelectric properties and dielectric properties of a gradient in the thickness direction changes functionally graded piezoelectric material;
