    Co-Authors: Xiao-gang Chen, Xian-jiang Song, Zhi-xu Zhang, Yuan-yuan Tang, Wan-ying Zhang, Pengfei Li, Jiazhen Ge, Dawei Fu, Rengen Xiong
    Abstract:

    Piezoelectric sensors that can work under various conditions with superior performance are highly desirable with the arrival of the Internet of Things. For practical applications, a large Piezoelectric Voltage Coefficient g and a high Curie temperature Tc are critical to the performance of Piezoelectric sensors. Here, we report a two-dimensional perovskite ferroelectric (4-aminotetrahydropyran)2PbBr4 [(ATHP)2PbBr4] with a saturated polarization of 5.6 μC cm–2, high Tc of 503 K [above that of BaTiO3 (BTO, 393 K)], and extremely large g33 of 660.3 × 10–3 V m N–1 [much beyond that of Pb(Zr,Ti)O3 (PZT) ceramics (20 to 40 × 10–3 V m N–1), more than 2 times higher than that of poly(vinylidene fluoride) (PVDF, about 286.7 × 10–3 V m N–1)]. Combined with the advantages of molecular ferroelectrics, such as light weight, easy and environmentally friendly processing, and mechanical flexibility, (ATHP)2PbBr4 would be a competitive candidate for next-generation smart Piezoelectric sensors in flexible devices, soft rob...

  • Giant Piezoelectric Voltage Coefficient in grain-oriented modified PbTiO 3 material
    Nature communications, 2016
    Co-Authors: Yongke Yan, Jie E. Zhou, Deepam Maurya, Yu U. Wang, Shashank Priya
    Abstract:

    A rapid surge in the research on Piezoelectric sensors is occurring with the arrival of the Internet of Things. Single-phase oxide Piezoelectric materials with giant Piezoelectric Voltage Coefficient (g, induced Voltage under applied stress) and high Curie temperature (Tc) are crucial towards providing desired performance for sensing, especially under harsh environmental conditions. Here, we report a grain-oriented (with 95% texture) modified PbTiO3 ceramic that has a high Tc (364 °C) and an extremely large g33 (115 × 10-3 Vm N-1) in comparison with other known single-phase oxide materials. Our results reveal that self-polarization due to grain orientation along the spontaneous polarization direction plays an important role in achieving large Piezoelectric response in a domain motion-confined material. The phase field simulations confirm that the large Piezoelectric Voltage Coefficient g33 originates from maximized Piezoelectric strain Coefficient d33 and minimized dielectric permittivity ɛ33 in [001]-textured PbTiO3 ceramics where domain wall motions are absent.

  • Magnetoelectric effect in composites of magnetostrictive and Piezoelectric materials
    Journal of Electroceramics, 2002
    Co-Authors: Jungho Ryu, Kenji Uchino, Shashank Priya, Hyoun-ee Kim
    Abstract:

    In the past few decades, extensive research has been conducted on the magnetoelectric (ME) effect in single phase and composite materials. Dielectric polarization of a material under a magnetic field or an induced magnetization under an electric field requires the simultaneous presence of long-range ordering of magneticmoments and electric dipoles. Single phase materials suffer from the drawback that the ME effect is considerably weak even at low temperatures, limiting their applicability in practical devices. Better alternatives are ME composites that have large magnitudes of the ME Voltage Coefficient. The composites exploit the product property of the materials. TheMEeffect can be realized using composites consisting of individual piezomagnetic and Piezoelectric phases or individual magnetostrictive and Piezoelectric phases. In the past few years, our group has done extensive research on ME materials for magnetic field sensing applications and current measurement probes for high-power electric transmission systems. In this review article, we mainly emphasize our investigations of ME particulate composites and laminate composites and summarize the important results. The data reported in the literature are also compared for clarity. Based on these results, we establish the fact that magnetoelectric laminate composites (MLCs) made from the giant magnetostrictive material, Terfenol-D, and relaxor-based piezocrystals are far superior to the other contenders. The large ME Voltage Coefficient in MLCs was obtained because of the high Piezoelectric Voltage Coefficient of the piezocrystals and large elastic compliances. In addition, an optimized thickness ratio between the Piezoelectric and magnetostrictive phases and the direction of the magnetostriction also influence the magnitude of the ME Coefficient.
