Ultrahigh strain in textured BCZT-based lead-free ceramics with CuO sintering agent

Flexoelectric enhanced film for an ultrahigh tunable piezoelectric-like effect

“…Moreover, the deformation range of these piezoelectric materials is micron-sized, while the UPSA in this work is applicable for centimeter-sized deformation. Comparing the state-of-the-art piezoelectric materials in the literature, including piezoelectric ceramics, 10,11,39–42 polymer composites, 43–47 polymers 48–53 and piezo-electrets, 18,31,32,54,55 the FEEF in this work has a profound significance in electromechanical devices with both tunable electromechanical capability and softness (Fig. 4F).…”

Observation of Micro-Scale Domain Structure Evolution under Electric Bias in Relaxor-Based PIN-PMN-PT Single Crystals

“…Notably, the PIN-PMN-33PT single crystals demonstrate an outstanding d 33 of 2556 pC/N under a DC-poling electric field of 15 kV/cm, which is higher than those ternary ferroelectric single crystals with high-temperature stability, such as PIN-43PMN-33PT single crystals (d 33 = 1760 pC/N), PIN-45PMN-31PT single crystals (d 33 = 1950 pC/N), PIN-46PMN-30PT single crystals (d 33 = 1750 pC/N) and PYbN-52PMN-33PT single crystals (d 33 = 1770 pC/N) [24,[41][42][43]. And, it is significantly higher than those ferroelectric ceramics that also possess hightemperature stability, such as PZT-5H ceramics (d 33 = 700 pC/N), textured PIN-PSN-PT ceramics (d 33 = 1090 pC/N), textured PNN-PZ-PT ceramics (d 33 = 1165 pC/N), and textured (Ba 0.95 Ca 0.05 ) (Zr 0.04 Ti 0.96 )O 3 ceramics (d 33 = 780 pC/N) [41,[44][45][46]. The exceptional piezoelectric performance and strain response indicate the significant potential of PIN-PMN-33PT single crystals for high-performance electromechanical devices.…”

Multi-Parametric Exploration of a Selection of Piezoceramic Materials for Bone Graft Substitute Applications

“…This created the premises for defining a new generation of macro-porous bone graft substitutes utilizing the piezoelectrical triggers for boosting bone regeneration, a subject which only recently, although rarely, started being tackled (e.g., BT [66], barium strontium titanate/β-TCP blends [67], BCTZ-simple [68] or coated with bioactive glass [69], or (K,Na)NbO 3 [70]). Besides the outcomes of the above-presented unitary screening research of a series of relevant piezoceramics, the (i) recognised excellent piezoelectric response of BCTZ [49], as well as the (ii) possibility to further improve its piezoelectric performance by future compositional and structural engineering [71][72][73][74][75][76][77], represent supplementary legitimate reasons for advancing BCTZ for the fabrication of macro-porous scaffolds.…”
