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 …

abstract In this review, the evolution of high strain Na 0.5 Bi 0.5 TiO 3-based lead-free
piezoceramics and their multilayer actuators has been explored. First, in terms of Na 0.5 Bi …

Ferroelectrics have a spontaneous electrical polarization that is arranged into domains and
can be reversed by an externally-applied field. This high versatility makes them useful in …

Abstract Large‐strain (K, Na) NbO3 (KNN) based piezoceramics are attractive for next‐
generation actuators because of growing environmental concerns. However, inferior …

The past two decades have seen a great enhancement of piezoelectric coefficients (d33) to
higher than 570 pC/N in (K, Na) NbO3 (KNN) piezoelectrics, but one notoriously unresolved …

Piezoelectricity as a physical property has received great attention due to its excellently
functional applications, especially in piezoelectric catalysis and mechanical energy …

Abstract SnO 2 doped Sr 0.6 (Na 0.5 Bi 0.5) 0.4 TiO 3 (NBT-ST) ceramics were prepared by
a conventional solid-state reaction method. Their phase structures, microstructures and …

Piezoelectric ceramics with combinatory soft and hard characteristics are highly desired for
high-power applications. However, it remains grand challenge to achieve simultaneous …

As one of the most crucial intrinsic contributions, defect dipoles show unique and prominent
influence on the responsive behavior of piezoelectric ceramics. Here, we present the …

The contradiction between high piezoelectricity and uniquely poor temperature stability
generated by polymorphic phase boundary is a huge obstacle to high-performance (K, Na) …
