TL;DR: A suite of Nb-based piezoelectric ceramics of 0.99[Bi 0.5 (Na 0.4 K 0.7 Sr 0.3 )TiO 3 (BNKTN-BST), with x ranging from 0 to 0.030, was prepared by a conventional solid-state reaction method as discussed by the authors.

TL;DR: In this paper, a lead-free piezoelectric material with a large strain response at a low driving field for actuator applications was developed, and the electric field required to deliver large strains was reduced to a level that revealed not only a large Smax/Emax of 542 pm/V at a driving field as low as 35kV/cm, but also remarkably suppressed the large hysteresis.

TL;DR: In this article, a phase transition from a tetragonal to cubic phase at x ≤ 0.005 was observed in the BNKT-BST-Lax ceramics and the recoverable field-induced phase transformation is suggested to be the main cause for the obtained large strain at x = 0.020.

TL;DR: A ternary solid solution (0.935 − x)BNT-0.065BT-xBi(Mn 0.5Ti0.5)O3 was designed and fabricated by means of a conventional fabrication process, and the composition and temperature dependencies of this material's dielectric, ferroelectric and strain behavior were systematically investigated as discussed by the authors.
