Modeling effects of microstructure for electrically active materials
A theoretical framework is proposed for the description of multifunctional material properties. The focus of this theory is on deriving equilibrium and kinetic equations for electrically active materials, particularly for rechargeable lithium-ion batteries and piezoelectric and electrostrictive …

TRANSVERSE RESONANCE ORTHOGONAL BEAM (TROB) SINGLE CRYSTAL UNDERWATER TRANSDUCERS
… transducers involving transmission and reception of large amounts of signals and information. In this research, using the excellent transverse piezoelectric properties and extremely high Poisson’s ratio of PZN-PT single crystals, a new drive mode for underwater projector, called the …

Development of Small-Footprint Large-Amplitude Tripod (three lambda) Mode Traveling Wave Generator
… with prototypes driven by twelve (12) PZN-PT single crystal active elements, which were arranged into 2 sets of 6 crystals each such that a travelling wave is generated at the end faces of the cylinder when two a.c. voltage signals of 90 degree phase difference were applied to …

Material characterization and modeling for piezoelectric actuation and power generation under high electromechanical driving levels
… and power generation of PZT-5H, single crystals PZN-PT, and single crystals PMN-PT. To model these observed material behaviors, one- and three-dimensional rate dependent nonlinear constitutive models based on thermodynamic potentials for PZT-5H and PZT-5A piezoelectric materials were then …

High Performance Lead--free Piezoelectric Materials
… of lead-based perovskite compositions (PZT, PMN-PT, PZN-PT etc.) have dominated the field in last few decades owing to their giant piezoresponse and convenient application relevant tunability. With increasing environmental concerns, in the last one decade, focus has been shifted towards …

Determination of local crystal symmetry in complex, multielement, ferroelectric perovskites and alloys
… domains having the monoclinic Pm symmetry in PZN-8%PT single crystals are identified by performing SCBED along the [100], [001], and [111] zone axes. Intensity distribution in the (000) disks in the CBED patterns is used to determine lattice-rotation at the precision of ±0.012° by performing …
