Direct-writing additive manufacturing of lead-free piezoelectric parts

By Jonathon Foreman / April 26, 2019

As additive manufacturing techniques become increasingly sophisticated, they offer a way to effectively construct specialized electronic devices. Two recent papers describe different direct-writing AM methods for constructing lead-free piezoelectric parts.

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…
