Breakthrough in understanding piezoelectric mechanism in Pb-free ferroelectrics

By Eileen De Guire / September 11, 2012

Applying a poling field (Epol) creates a rhombohedral (R)/tetragonal (T) morphotropic phase boundary in a single phase grain of (Bi½Na½)TiO3-6%BaTiO3. Such direct in-situ transmission electron microscopy observations led to the establishment of an Epol vs x phase diagram for (1-x)(Bi½Na½)TiO3–xBaTiO3. Credit: Tan; Iowa State University. Lead zirconate titanate ceramics are the “gold standard” materials for…

Zhong-Lin Wang takes nanoscale piezo energy scavenging to heart

By / June 11, 2010

ACerS member Zhong-Lin Wang continues to make interesting progress on developing nanowire power generators and other energy-scavenging devices, and recently has demonstrated a nanogenerator that can be powered by the motion of a beating heart or the flexing of diaphragms and lungs. When I last wrote about Wang in early 2009, he was demonstrating a…

Group shows hysteretic behavior of ferroelectric materials changes at nanoscale

By / May 20, 2010

A collaborative group of researchers from Oak Ridge National Lab, Penn State, the Univ. of Sheffield (U.K.) and EPFL (Switzerland) have made a discovery that overturns some 100-year-old assumptions about the behavior of polycrystalline and other ferroelectric materials. In brief, the nonlinear materials responses and associated enhanced electromechanical properties that occur at the microlevel stop…
