This paper puts forward a line spectrum extraction method of seismic-acoustic signal. The method is based on the difference in the polarization characteristics between signal and noise. The data of two horizontal channels are analyzed and the frequency domain polarization parameters are extracted by using singular value decomposition (SVD) method. The resolution of the polarization to frequency is improved by using multi-layer autocorrelation. Experimental results show that the polarization method can extract line spectrum adaptively, and the method based on multi-layer autocorrelation has a good line spectrum extraction performance. The signal to noise ratio (SNR) of the spectrum has been greatly improved.

The Aluminum Nitride (AlN) thin film based surface acoustic wave sensors have been fabricated by whole CMOS compatible process. In order to study the resonant frequency behavior responses with temperature, S parameters measured by network analyzer of the AlN SAW sensors are processed with the data extraction program through MATLAB software. It is observed the extracted data of resonance frequency show linear relationship with variation of environment temperatures, which indicates we can easily carry out temperature compensation for the fabricated AlN SAW sensors. And the studied AlN based SAW sensor could also be employed as temperature sensor for further wireless sensing applications.

(0.9-x)(Bi0.95La0.05)FeO3-xPbTiO3-0.1BaZrO3 (BLF-xPT-BZ) ceramics were synthesized by the conventional solid state reaction method. The X-ray diffraction (XRD) results reflected that phase transformation from rhombohedral (R) to tetragonal (T) took place with increasing the PT content, and the coexistence R and T phases were observed at x = 0.35. The dielectric constant (εr), dielectric loss (tanδ), remnant polarization (Pr) and piezoelectric coefficient (d33) increased initially and then decreased with increasing the PT content, and reach to maximum at x = 0.35. The TC, Td, εr, d33, S and kp of 0.55BLF-0.35PT- 0.1BZ were 422 °C, 380 °C, 620, 162 pC/N, 0.3 % and 0.272, respectively. It was interesting that the maximum strain of BLF-xPT-BZ ceramics achieves about 0.3% under the electric field of 75 kV/cm, which was larger than that of BiScO3-PbTiO3 ceramics.

Theoretical models of beam piezoelectric phononic crystal have been proposed, where piezoelectric patches and other elastic structure are arrayed periodically. Each piezoelectric patch is connected by a resonant shunting circuit independently. Three kinds of piezoelectric patches, i.e., bimorph in series and in parallel, and unimorph, are taken into consideration. The coupling interaction between Bragg and locally resonant band gaps is investigated. The numerical results have demonstrates that it is feasible to obtain specific band gaps through adjusting the interaction between band gaps by inductance. This characteristic can enhance the applicability of phononic crystals.

This paper presents a piezoelectric energy harvester (PEH) which can convert fluid kinetic energy into electricity with vortex induced vibration (VIV). The PEH is composed by a piezoelectric cantilever beam and a cylinder extension. Dynamic response and energy harvesting of the PEH are studied numerically. It is found that maximum output power can be obtained with optimal resistance and the more power output, the stronger elimination of vibration amplitude. Vibration frequency makes greater contribution on power output at smaller cylinder diameter and decreases with increasing of cylinder diameter. Vibration amplitude plays main role on output power and increases first until reaching peak point with increasing of cylinder diameter. Maximum output power can be obtained with reasonable cylinder diameter.

Volumetric HIFU ablation has been implemented in clinical practice to create large thermal lesion while reducing treatment durations. However, it still takes several hours to cover the whole target using volumetric ablation. Multiple focus intensity patterns have been proved beneficial to create larger lesions. The feasibility of dual-focus scanning in volumetric ablation has been evaluated. Simulations of dual-focus scanning and single-focus scanning were performed with the treatment cells of 4, 8, 12 and 16 mm in diameter. Comparison of both scanning approaches indicates that the dual-focus scanning saves treatment time by 20% and needs lower peak acoustic pressure, therefore the potential cavitation could be avoided. Although the maximum near-field temperatures are slightly higher than single-focus scanning, they are acceptable in HIFU treatment.

Lead potassium niobate (Pb2KNb5O15, PKN) single crystal with tungsten bronze has been successfully grown by Bridgman method through spontaneous nucleation. Under the optimized growth conditions, the crystal was transparent, cracks free and inclusions free. The mechanical property was measured through the Vickers microhardness technique. The result showed that the relationship between the Vickers' microhardness and load could be described as Hv=1.90P-0.2057GPa. Strip-shaped domains were observed in PKN crystals. The changes of the domains during the temperature increasing process indicated that the Currie temperature of PKN was in the range of 460-470°C.

Image-guide high-intensity focused ultrasound (HIFU) has been widely used in the treatment of uterine fibroids. However, before HIFU system is ready for use, the targeting accuracy should be known for the safety of important abdominal organs surrounding the target. Researchers have used magnetic resonance (MR) images or computed tomography (CT) to evaluate the targeting accuracy of current MR-guided HIFU systems, whereas these methods cannot be directly used in the ultrasound-guided HIFU (USgHIFU) systems. In this study, a thermocouple array is used in combination with the in-house built acrylic plate to evaluate the targeting accuracy of the existing 112-channel phased-array USgHIFU system. The results of ex vivo experiment demonstrate the feasibility and the efficacy of the thermocouple array in the evaluation, and the targeting accuracy of the USgHIFU system is about 1mm in the focal plane. Thus, this accuracy is adequate for the treatment of uterine fibroids.
