“…For the last 20 years, composite piezoelectric materials have been developed by combining piezoceramics with passive nonpiezoelectric polymers [1][2][3]. Superior properties have been achieved by these composites by taking advantage of the most profitable properties of each of the constituents and a great variety of structures have been designed.…”

The piezoelectric effect is studied for bending and traction tests for two types of structure configurations: homogeneous and composite structures. Mechanical displacements are calculated for traction and bending tests, using FEM for the homogeneous body, where the input material properties are taken from the overall coefficients reported by the Asymptotic Homogenization Method (AHM). A brief theoretical description about the basics of the piezoelectric finite elements and the AHM is given. On the other hand, the calculations of the mechanical displacements are done for the composite structure using FEM where the real data of the material parameters for cylindrical fibers (PZT-5) embedded in a matrix (elastic isotropic polymer) were taken from reported references. A comparison between the results obtained using AHM + FEM and FEM for the homogeneous and the composite structures respectively is reported and shows a favorable result.

“…Recently, domain-engineered single crystals such as lead magnesium niobate-lead titanate (PMN-PT) have been developed. [4][5][6] Even though these crystals take a longer time to manufacture, they offer exceptional performance. Once poled, nearly all the electric dipole domains are aligned with the poling field.…”

“…The popularity of this diagnostic tool is due to its ability to produce real-time, high-resolution three-dimensional images of internal soft body tissue without the use of potentially hazardous ionizing radiation such as X-rays. A more detailed discussion of the well-established biomedical imaging applications can be found elsewhere [8][9][10].…”

Piezoelectric ceramic-polymer composites have been conceptualized, prototyped, fabricated by rapid prototyping in order to surpass those fabricated with traditional processing methods in novelty as well as performance. Rapid prototyping offers unmatched design and fabrication flexibility in achieving structural complexity and hierarchy in developing piezoelectric composites. A detailed account of all salient aspects of Fused Deposition of Ceramics (FDC) and Fused Deposition of Multi-Materials (FDMM), two major technologies pioneered at Rutgers University, are discussed. Structureprocessing-property relations are elaborated on using connectivity as the unifying central concept. Examples of novel piezoelectric ceramic-polymer composites fabricated using FDC and FDMM are given, and pertinent electromechanical properties are discussed. Pending challenges in this line of research are also elaborated on.
