“…[58][59][60] A number of researchers have discussed similar behavior in various ferroelectric and antiferroelectric materials using domain dynamics. [61][62][63][64] In a similar fashion, glass also induces domain clamping or domain pining by means of internal-confinement. Hence, the dielectric constant is reduced with increasing glass content, as shown in figure 6(a).…”

Influence of structural evolution on energy storage properties in Bi 0.5 Na 0.5 TiO 3 -SrTiO 3 -NaNbO 3 lead-free ferroelectric ceramics Journal of Applied Physics 121, 054103 (2017) This study systematically investigates the phenomenon of internal clamping in ferroelectric materials through the formation of glass-ceramic composites. Leadfree 0.715Bi 0.5 Na 0.5 TiO 3 −0.065BaTiO 3 −0.22SrTiO 3 (BNT-BT-ST) bulk ferroelectric ceramic was selected for the course of investigation. 3BaO − 3TiO 2 − B 2 O 3 (BTBO) glass was then incorporated systematically to create sintered samples containing 0%, 2%, 4% and 6% glass (by weight). Upon glass induction features like remnant polarization, saturation polarization, hysteresis losses and coercive field could be varied as a function of glass content. Such effects were observed to benefit derived applications like enhanced energy storage density ∼174 k J/m 3 to ∼203 k J/m 3 and pyroelectric coefficient 5.7x10 −4 Cm −2 K −1 to 6.8x10 −4 Cm −2 K −1 by incorporation of 4% glass. Additionally, BNT-BT-ST depolarization temperature decreased from 457K to 431K by addition of 4% glass content. Glass incorporation could systematically increases diffuse phase transition and relaxor behavior temperature range from 70 K to 81K and 20K to 34 K, respectively when 6% and 4% glass content is added which indicates addition of glass provides better temperature stability. The most promising feature was observed to be that of dielectric response tuning. It can be also used to control (to an extent) the dielectric behavior of the host ceramic. Dielectric permittivity and losses decreased from 1278 to 705 and 0.109 to 0.107 for 6% glass, at room temperature. However this reduction in dielectric constant and loss increases pyroelectric figures of merit (FOMs) for high voltage responsivity (F v ) high detectivity (F d ) and energy harvesting (F e ) from 0.018 to 0.037 m 2 C −1 , 5.89 to 8.85 µPa −1/2 and 28.71 to 61.55 Jm −3 K −2 , respectively for 4% added ceramic-glass at room temperature. Such findings can have huge implications in the field of tailoring ferroelectric response for application specific requirements. C 2015 Author(s).

“…Ferroelastic domain switching in BNT-FE exhibits quite different behaviors as compared to both soft and hard lead zirconate titanate ͑PZT͒. 17,18 In PZT, domain switching occurs in a comparatively narrow range of applied stress, while in BNT-FE, switching occurs over a very wide stress range, being most active at around 200 MPa. The resistance for ferroelastic domain switching in BNT-FE is much higher than in hard PZT ceramics ͑ϳ100 MPa͒.…”

“…The resistance for ferroelastic domain switching in BNT-FE is much higher than in hard PZT ceramics ͑ϳ100 MPa͒. 17,18 Consistent with this, the domain switching resistance under electric fields ͑indicated by the coercive field E c ͒ in BNT-FE is also more than twice as large as in hard PZT ceramics ͑35 kV/cm versus16 kV/cm͒. 17 The combination of the large electric field-induced strain and the high resistance of ferroelastic domain switching makes the BNT-FE ceramic promising for actuator applications, where a large blocking stress is desired.…”

Prior studies have shown that a field-induced ferroelectricity in ceramics with general chemical formula (1−x−y)(Bi1/2Na1/2)TiO3-xBaTiO3-y(K0.5Na0.5)NbO3 and a very low remanent strain can produce very large piezoelectric strains. Here we show that both the longitudinal and transverse strains gradually change with applied electric fields even during the transition from the nonferroelectric to the ferroelectric state, in contrast to known Pb-containing antiferroelectrics. Hence, the volume change and, in turn, the phase transition can be affected using uniaxial compressive stresses, and the effect on ferroelectricity can thus be assessed. It is found that the 0.94(Bi1/2Na1/2)TiO3-0.05BaTiO3-0.01(K0.5Na0.5)NbO3ceramic (largely ferroelectric), with a rhombohedral R3c symmetry, displays large ferroelectric domains, significant ferroelastic deformation, and large remanent electrical polarizations even at a 250 MPa compressive stress. In comparison, the 0.91(Bi1/2Na1/2)TiO3-0.07BaTiO3-0.02(K0.5Na0.5)NbO3ceramic (largely nonferroelectric) possesses characteristics of a relaxor ferroelectricceramic, including a pseudocubic structure, limited ferroelastic deformation, and low remanent polarization. The results are discussed with respect of the proposed antiferroelectric nature of the nonferroelectric state.

“…This is easily explained by the presence of stress based d 31 enhancement. It has been shown [1], [13], [26], [27] that compressive stress on PZT degrades the piezoelectric coupling coefficients while tensile stress causes an enhancement. Applying a load to the distal end of a bimorph actuator puts the PZT plate which is doing work on the load in tension, causing the above phenomena.…”

Abstract-To keep pace with recent advances in microrobotic structures demands actuator technologies which can deliver high power and precise motion. For electroactive material based actuators, high power typically implies either high field or high current drives which may lead to greater nonlinearities such as saturation, softening, and increased loss. Physical modeling of actuators is normally taken to be linear since the range of displacements, applied loads, and applied fields is typically small. If extrapolated to high drive conditions, these linear models significantly over predict the power which can be delivered. For actuators driving dynamic systems, a complete nonlinear model of the system will improve controllability and give more accurate estimations of power delivery capabilities. Here static nonlinearities and dynamic linear and nonlinear parameters are derived for high performance piezoelectric bending actuators.
