Reducing or even prohibiting the use of toxic lead in electronic devices has become one of
the most cutting-edge topics in various disciplines. The recently proposed phase boundary …

A comprehensive review of aging and fatigue phenomena in bulk polycrystalline
ferroelectrics is presented. Three material classes are covered, namely the most widely used …

The piezoelectric properties of lead zirconate titanate [Pb (Zr, Ti) O3 or PZT] ceramics could
be enhanced by fabricating textured ceramics that would align the crystal grains along …

Piezoelectric materials provide high strain and large driving forces in actuators and can
transform electrical energy into mechanical energy. Although they were discovered over 100 …

High‐performance lead‐free piezoelectric materials are in great demand for next‐
generation electronic devices to meet the requirement of environmentally sustainable …

Here, we introduce phase change mechanisms in lead-free piezoceramics as a strategy to
utilize attendant volume change for harvesting large electrostrain. In the newly developed …

High piezoelectricity of (K, Na) NbO3 (KNN) lead‐free materials benefits from a polymorphic
phase transition (PPT) around room temperature, but its temperature sensitivity has been a …

We report the first direct evidence that the morphotropic phase boundary in ferroelectric
materials, along with the associated strong piezoelectricity, can be created, destroyed, or …

Designing high-performance piezoelectric materials based on atomic-scale calculations is
highly desired in recent years, following the understanding of the structure-property …

Studies on the piezoelectric materials capable of efficiently outputting high electrostrains at
low electric fields are driven by the demand for precise actuation in a wide range of …
