Freestanding PZT Films for Integrated Wearable Sensing and Intelligent Acoustic Recognition [PDF]

Advanced science
A freestanding epitaxial PZT/LaNiO3/Pt heterostructure is achieved via water‐assisted delamination from mica, effectively eliminating substrate‐induced clamping and releasing intrinsic ferroelectricity. The released film exhibits substantially enhanced remanent polarization and piezoelectric response, delivering excellent mechanical flexibility and ...

Investigation of Ga Doping for Non-stoichiometric Sodium Bismuth Titanate Ceramics [PDF]

Journal of Materials Science: Materials in Electronics, 2021
Abstract The electrical performance of Ga3+ doping Na0.5Bi0.5TiO3-based oxygen ion conductor was studied. The Na0.52Bi0.47Ti1−xGaxO3−δ (x = 0, 0.01, 0.015, 0.02) samples were fabricated by the means of traditional solid-state reaction. The results of AC impedance measurement show that the bulk conductivity of Na0.52Bi0.47Ti1−xGaxO3−δ samples ...

Electromechanical properties of sodium bismuth titanate thin films

Thin Solid Films, 2022
Lead-free piezoelectric sodium bismuth titanate (BNT) films are promising candidates for actuators applications as an alternative to lead zirconate titanate films. We focused in this work on the growth and characteristics of BNT films deposited by sputtering on silicon substrates with LaNiO3 electrodes.

Effect of bismuth titanate on the properties of potassium sodium niobate-based ceramics

Journal of Asian Ceramic Societies, 2017
The effect of modifying the properties of KNN-based ceramics with Bi2Ti2O7 (BiT) been investigated in this work. The density measurements show that additions of BiT to the samples slightly increase the density values.

NaNbO3 modulated phase transition behavior and antiferroelectric stability evolution in 0.88(Bi0.5Na0.5)TiO3-0.12BaTiO3 lead-free ceramics

Journal of Materiomics, 2022
Giant strains in (Bi0.5Na0.5)TiO3 based ceramics are usually attributed to electric field induced nonpolar to polar phase transition. Whether it is an ergodic relaxor R3c/P4mm ferroelectric (FE) to long-range ordered FE phase transformation or a ...
