“…The meanings of X, Y, x and y in formula (10) are the same as formula ( 9), combined with the previous algorithm equation, an analytical formula of equivalent constant can be obtained. The solution method of inclusion theory can better reflect the actual situation of the material, and the accuracy of the solution is relatively high, but it also has shortcomings [19].The calculation and problem-solving of inclusion theory are relatively cumbersome, and sometimes only numerical methods can be used to solve equations.…”

Piezoelectric ultrasonic transducer is the most important functional device in the field of ultrasound, as an important part of piezoelectric ultrasonic transducer-piezoelectric material, the improvement of its performance plays an important role in promoting the innovation and development of piezoelectric ultrasonic transducers. This article aims to conduct a finite element study based on the 1-3 piezoelectric composite ferroelectric material of the smart medical ultrasonic diagnostic transducer. In this article, the working principle and function of the ultrasonic transducer are explained first. The ultrasonic transducer is classified, and the FEM analysis of the 1-3 piezoelectric composite ferroelectric material and the ANSYS FEM analysis method are introduced. The influence of PZT volume fraction, aspect ratio and the number of primitives on the finite element model of the 1-3 spherical-crown piezoelectric composite is mainly discussed, and then verified by experiments and ANSYS performance analysis of ultrasonic diagnostic transducers. The research results show that the thickness electromechanical coupling factor of the 1-3 piezoelectric composite material is affected by the thickness electromechanical coupling coefficient of the piezoelectric phase material, the volume fraction of the piezoelectric phase, and the width-to-thickness ratio. When the aspect ratio is increased to 0.7, the electromechanical coupling coefficient of the thickness with a volume fraction of 80% is reduced by 79%.The electromechanical coupling coefficient of the thickness with a volume fraction of 60% is reduced by 73%, and the electromechanical coupling coefficient of the thickness with a volume fraction of 20% is reduced by 68%.

“…Since the discovery of piezoelectric phenomenon in lead-based such as Pb(Zr,Ti)O3 (PZT) and Pb(Mg,Nb)O3-PbTiO3 (PMN-PT) have been widely used in an electronic industry for various applications, i.e. energy harvesting systems, actuators and sensors [1]. However, environmental concerns with regard to harmful elements have accelerated the study of lead-free piezoelectric ceramics, i.e.…”

The BNKBST30 + 3 vol% Fe2O3 ceramic was fabricated via a solid-state mixed oxide and sintered 1125°C for 2 h. The effects of ferric oxide nanoparticles (Fe2O3) additive on phase evolution, microstructure and electrical properties, i.e. dielectric, ferroelectric and electric field-induced strain, of BNKBST30 ceramic was investigated. The obtain ceramic was well sintered and densely with high density of 5.78 g/cm3. X-ray diffraction pattern and Raman spectra analysis showed a single perovskite with a mixed rhombohedral (R3c) and tetragonal (P4bm) phases. The obtained ceramic had a cubic-like grain shape with an average grain size of 0.82 µm. The dielectric constant as a function of temperature curves exhibited broad transition peaks at maximum temperature (Tm). The ceramic also showed good dielectric (er = 1085, tan d = 0.0496, er,max = 6099, Tm = 296 °C), ferroelectric (Pr = 27.18 µC/cm2, Ec = 20.32 kV/cm, Rsq = 0.95), and electric field-induced strain properties (Smax = 0.22 %, Sneg = - 0.08 %, d*33 = 440 pm/V). The obtained results indicated that the studied ceramic is considered as candidate for lead-free electromechanical applications.
