Numerical investigations of field-defect interactions in piezoelectric ceramics

Experimental and numerical investigations on microstereolithography of ceramics

Microstereolithography ~mSL! uses laser light to solidify UV-curable resin mixed with concentrated ceramic powders. During the mSL process, the light scattering from the particle suspension is found to significantly influence the fabrication resolution in both lateral and depth dimensions which are critical for the complex three-dimensional ~3D! microfabrication. In this work, we performed Mont...

Characterisation of Piezoelectric Ceramics

The IEEE standard on piezoelectricity recommends methods to determine the coefficients of piezoelectric ceramics and the sizes of the samples to be used. A method to determine the difference between the actual coefficients and the coefficients determined using the IEEE standard is presented. The difference or error for samples of various shapes and sizes is presented. These errors and manufactu...

Piezoelectric Ceramics Characterization

This review explores piezoelectric ceramics analysis and characterization. The focus is on polycrystalline ceramics; therefore, single crystals, polymeric materials and organic/inorganic composites are outside the scope of this review. To thoroughly grasp the behavior of a piezoelectric polycrystalline ceramic, a basic understanding of the ceramic itself should not be overlooked. To this end, w...

pharmaceutical application of nanocrystalline piezoelectric ceramics

Non-linear Properties of Piezoelectric Ceramics

Sensors and actuators based on piezoelectric ceramics are finding an increasingly large variety of applications under a very wide range of environmental conditions and applied signals. Some actuator applications require the piezoelectric materials to support large mechanical loads and produce high strain output. In order to accomplish this requirement of higher strains, large electric fields mu...
