Giant piezoelectric voltage coefficient in grain-oriented modified PbTiO3 material
A rapid surge in the research on piezoelectric sensors is occurring with the arrival of the Internet of Things. Single-phase oxide piezoelectric materials with giant piezoelectric voltage coefficient (g, induced voltage under applied stress) and high Curie temperature (Tc) are crucial towards providing desired performance for sensing, especially under harsh environmental conditions. Here, we re...
متن کاملGiant strain with ultra-low hysteresis and high temperature stability in grain oriented lead-free K0.5Bi0.5TiO3-BaTiO3-Na0.5Bi0.5TiO3 piezoelectric materials
We synthesized grain-oriented lead-free piezoelectric materials in (K0.5Bi0.5TiO3-BaTiO3-xNa0.5Bi0.5TiO3 (KBT-BT-NBT) system with high degree of texturing along the [001]c (c-cubic) crystallographic orientation. We demonstrate giant field induced strain (~0.48%) with an ultra-low hysteresis along with enhanced piezoelectric response (d33 ~ 190pC/N) and high temperature stability (~160°C). Trans...
متن کاملFree Vibration Analysis of Functionally Graded Piezoelectric Material Beam by a Modified Mesh Free Method
A mesh-free method based on moving least squares approximation (MLS) and weak form of governing equations including two dimensional equations of motion and Maxwell’s equation is used to analyze the free vibration of functionally graded piezoelectric material (FGPM) beams. Material properties in beam are determined using a power law distribution. Essential boundary conditions are imposed by the...
متن کاملFirst-principles study of „BiScO3...1Àx-„PbTiO3...x piezoelectric alloys
We report a first-principles study of a class of (BiScO3)12x-(PbTiO3)x ~BS-PT! alloys recently proposed by Eitel et al. as promising materials for piezoelectric actuator applications. We show that ~i! BS-PT displays very large structural distortions and polarizations at the morphotropic phase boundary ~MPB! ~we obtain a c/a of ;1.05–1.08 and P tet'0.9 C/m ); ~ii! the ferroelectric and piezoelec...
متن کاملDirect observations of electric field-induced domain boundary cracking in Š001‹ oriented piezoelectric Pb„Mg1Õ3Nb2Õ3...O3–PbTiO3 single crystal
In situ transmission electron microscopy study of electric field-induced cracking has been conducted on ^001& oriented 0.65Pb~Mg1/3Nb2/3!O3 – 0.35PbTiO3 crystal. Fracture of the 90° domain boundary was directly observed in the tetragonal area under both static and alternating electric fields. The field strength required to induce domain boundary cracking was lower for alternating electric field...
