  • Love wave propagating in a piezoelectric material structure with a mass layer

    An analytical approach is taken to investigate Love wave propagating in layered piezoelectric structure where a thin piezoelectric film with a mass layer bonded to a semi-infinite elastic substrate. The governing equations of Love waves can be obtained on the basis of the linearly piezoelectric theory. The displacements, electric potential, stresses and electric displacement are continuous across the interface of the piezoelectric film and the substrate together with the electrically open and short conditions on the interface of the piezoelectric film and the mass layer. The analytical solution of dispersion relations are obtained for mechanical and electrical boundary conditions for the piezoelectric film of BaTiO3 and the substrate of SiO2. The phase velocity is calculated and figured. The distributions of the displacements, electrical potential and shear stress are also investigated and figured. The effect of the thickness of the mass layer on the properties of the Love waves is discussed in detail.

  • Effect of asymmetric piezoelectric multimorph ceramic on frequency response characteristics of piezoelectric acoustic actuator

    This paper proposes an asymmetric piezoelectric multimorph ceramic to improve sound quality of the piezoelectric acoustic actuator which means flat and smooth frequency response characteristics on a wide playing frequency range. In order to investigate the effect of asymmetric piezoelectric multimorph ceramic on the frequency response characteristics of the piezoelectric acoustic actuator, we compared and analyzed the vibrational frequency response and output acoustic characteristics of the piezoelectric acoustic actuators fabricated with 2 types of 3-3 symmetric and 2-4 asymmetric piezoelectric multimorph ceramics. The significant dip of 5 kHz in the output sound pressure of 2-4 asymmetric piezoelectric ceramic speaker was not only greatly by 20 dB, but the percentage of THD at 5 kHz was dramatically reduced from 96 % to 39 %, compared to the results of 3-3 symmetric piezoelectric ceramic speaker. As a result, it is obvious that the asymmetric piezoelectric multimorph ceramic can improve the sound quality of the piezoelectric acoustic actuator to have flat and smooth frequency response characteristics, compared to the symmetric piezoelectric multimorph ceramic.

  • Capacitance force piezoelectric extraction

    The functionality of the piezoelectric materials is being used in many integrated applications due to their electrical-mechanical reciprocity. Here we have demonstrated that piezoelectric film coefficient can be characterized using capacitance force direct relationship. The proposed technique makes such determination by taking the measuring the capacitance of a piezoelectric disk with the application of mechanical force under a set of assumptions in deriving the equations for the d33 coefficient. Both; the classical parallel plate capacitance analysis and piezoelectric material theory are used to calculate the capacitance variation in lead zirconate titanate (PZT) film, enabling piezoelectric coefficient to be determined. The technique fits well sheet characterization avoiding any complicated preparation and uses arbitrary sample geometry. The values of the coefficients obtained experimentally are found to be similar to those that have been determined by more elaborate methods.

  • Gap wave propagating in layered piezoelectric material structures with initial stress

    In this study, shear horizontal gap waves propagating in layered piezoelectric structures with initial stress is investigated analytically. The boundary conditions imply that the displacement, shear stress, electric potential, and electric displacement are continuous across the interface between the layer and the substrate. The electrically open conditions at the interface between the air and the piezoelectric layer are applied to solve the problem. The phase velocity equation can be obtained and the velocity is numerically calculated and discussed in detail for different initial stresses in the piezoelectric layer. We find that the initial stress has remarkable effect on the phase velocity of the gap waves.

  • Simulation of the self-sensing actuators based on multi-piezoelectric effects of piezoelectric crystal

    Based on the theory of classical piezoelectricity and the rapid development of piezoelectric material today, it has become possible to integrate structure and function of sensor with actuators into the single piezoelectric element. This paper analyzes and simulates integrated sensor-actuators using coupled- field analysis function in the finite element analysis software ANSYS for 3-D finite element model which of models is PZT-5 piece. In the beginning of positive piezoelectric effect, the results show that voltage and displacement generated by secondary converse piezoelectric effects respectively have linear relationship with the applied outside force. The simulation results are proved that the functions of sensors and actuators can be integrated in the single piezoelectric crystal.

  • The research of damped absorbing layer based on piezoelectric shunt

    Piezoelectric passive control is a piezoelectric shunt damping technology that utilizes the piezoelectric effect of a piezoelectric material to convert the mechanical energy generated by the structural vibration of a sound wave incident on a piezoelectric device into electrical energy. By connecting a shunt circuit in parallel with the piezoelectric device, the resistance in the shunt circuit converts the electric energy into heat energy so as to achieve the purpose of suppressing the structural vibration and improving the sound absorption performance. In the article, the negative capacitance is used to counteract the capacitive reactance of the piezoelectric film, increase the electromechanical coupling coefficient of the piezoelectric film and improve the controllability of the system. We also analyze when a rigid piezoelectric material connected to the back of piezoelectric damping material, the method can improve the efficiency of electrical-acoustic conversion, and enhance the sound absorption ability of the material. At the same time, this paper also studies the role of rubber damping material in the piezoelectric shunt damping sound absorption layer, designed a sound absorbing structure with wide frequency range and high absorption coefficient.

  • Nanowires piezoelectric constants determination using current-voltage measurements

    This work demonstrates an original method using the electromechanical properties of the zinc oxide (ZnO) piezoelectric nanowires to characterize its piezoelectric voltage coefficient (d<sub>33</sub>). The proposed technique utilizes the current-voltage (IV) measurements coupled with the application of variable force to cause a change in the corresponding IV relationship. To conduct the IV measurements, the nanowire is integrated inside a field effect transistor (FET) to form the channel of the device, while it is suspended over a trench. The indentation of the nano-wire causes the mechanical deflection of the suspended nanowire which through the piezoelectric effect changes the IV characteristics of the FET. The extraction of the piezoelectric coefficient is done by modifying the standard FET IV model to incorporate the change in the channel length which is triggered by the piezoelectric behavior. Embedded within this change of length is piezoelectric coefficient and therefore, it becomes straightforward procedure to extract this coefficient from the changes in the IV characteristics.

  • Piezoelectric Micromachined Ultrasonic Transducer Using Silk Piezoelectric Thin Film

    In this letter, we present for the first time, a successful fabrication and characterization of silk piezoelectric thin film-based piezoelectric micromachined ultrasonic transducer (PMUT). One of the exacting problems in the PMUT research is to find a suitable piezoelectric material to be used as the sensing and actuating element. Utilizing its innate piezoelectricity, we have used ultra-smooth silk thin film (RMS roughness = 2.84 nm, d<sub>33</sub> = 56.2 pm/V) as the piezoelectric element of the PMUT. The silicon membrane of the PMUT is realized by bulk micromachining. The challenging task of integrating the silk thin film above the micromachined membrane is successfully accomplished and the device functionality is demonstrated. The silk PMUT exhibited center frequency at 76.59 kHz with a fractional bandwidth of 3.18 %, when characterized in air.

  • An analysis of propagation of surface acoustic waves in rotating piezoelectric plates

    As an important application of acoustic wave sensors, gyroscopes for rotation sensing purpose can also utilize surface acoustic waves in piezoelectric substrates. This requires an analysis of surface acoustic waves propagating in finite piezoelectric solids to aid the design process in parameter selection and optimization. Earlier studies have investigated the effect of rotation in semi-infinite piezoelectric solids, but result like this can only be considered as an approximation to actual gyroscopes with finite substrates. In this study, we consider the substrate as an infinite piezoelectric plate with finite thickness, thus enabling us to calculate the surface acoustic wave velocity in a rotating plate. It is known that there is only one velocity in a semi-infinite solid, but there will be two velocities if we study surface waves in an infinite plate. It is also found that both velocities are changed by the rotation. The numerical results on AT- and ST-cut quartz crystal show that both velocity branches have been changed and the two velocities can be clearly observed if the thickness of plate is less than three wavelengths. If the substrate is to be considered as a semi-infinite, the plate thickness has to be larger than three wavelengths. In this case, the effect of rotation on the velocity still exists, but the two modes essentially merged into the Rayleigh wave velocity. The velocity shifts due to rotation is different from the semi-infinite substrate, offering improved references and guidance in the substrate and material selection for rotation piezoelectric sensors. The extension of this study can be done with the application of two-dimensional theory for surface acoustic waves in finite plates.
