This chapter presents a brief summary of the basic theory of linear piezoelectricity based mainly on the IEEE Standard on Piezoelectricity [1] and the classical book on piezoelectricity [2] by H. F. Tiersten who also wrote the theoretical part of [1]. The organization of this chapter is essentially a shortened version of Chapter 2 of An Introduction to the Theory of Piezoelectricity [3]. This chapter...
This volume is intended to provide researchers and graduate students with the basic aspects of the continuum modeling of electroelastic interactions in solids. A concise treatment of linear, nonlinear, static and dynamic theories and problems is presented. The emphasis on formulation and understanding of problems useful in device applications rather than solution techniques of mathematical problems...
The theory of piezoelectricity is based on a quasistatic approximation [1]. As a result, in this theory, although the mechanical equations are dynamic, the electromagnetic equations are static, and the electric field and the magnetic field are not dynamically coupled. Therefore, the theory of piezoelectricity does not describe the wave behavior of electromagnetic fields. For many applications in piezoelectric...
Classical continuum theories such as elasticity, electrostatics, and piezoelectricity are the long-wave and low-frequency limits of the equations of lattice dynamics. The partial differential equations of these continuum theories can be obtained from the finite difference equations of lattice dynamics by Taylor expansions and truncations. The equations of classical continuum theories are accurate...
Piezoelectricity has been a steadily growing field, with recent advances made by researchers from applied physics, acoustics, materials science, and engineering. This collective work presents a comprehensive treatment of selected advanced topics in the subject. Every chapter is self-contained and written by international experts who elaborate on special topics. Key features include: * Systematic...
Due to the unpredictable occurrences of serious blackout in power system, the importance of wide area measurement system has been highlighted. By using the data of phase measurement units (PMU) installed over the power grid, the indices of power system security and stability can be retrieved. As a result, based on the reflected dynamic information people have successfully implemented accurate power...
Empirical mode decomposition (EMD) method is a novel time-frequency analysis tool to analyse non-stationary signals, which decomposes the signal concerned into intrinsic mode functions (IMFs) modulated in terms of both amplitude and frequency. The original version of EMD, however, suffers from an algorithm difficulty to separate two individual components, frequencies of which are within an octave...
We summarize our recent results on the study of electrode size and shape for a few common cuts of quartz and langasite plate thickness-shear mode piezoelectric resonators. Optimal electrode shape and size satisfying Bechmann's number in every direction are determined.
Langasite is of interest for resonator applications for several reasons including its good temperature behavior, good piezoelectric coupling, low acoustic loss and high Q factor. Biasing effects for such resonators, crucial for design applications, depend on an accurate understanding of the effects from nonlinear material constants. Accurate experimental determination of the nonlinear elastic, piezoelectric,...
