“…where b a f f f D = -A recently proposed electrical power method for calculating mechanical quality factor showed that the maximum mechanical quality factor occurs between resonance and anti-resonance frequencies while the previous methods (impedance and burst) were limited to provide the mechanical quality factor only at resonance and anti-resonance frequencies [22][23][24].…”

-Piezoelectricity is the capability of a piezoelectric material to change mechanical energy into electrical energy. The determination of electrical and mechanical properties plays a significant role in characterizing the piezoelectric material. The energy losses characteristics of piezoelectric material can be described by mechanical quality factor. In this paper, the output voltage and mechanical quality factor of Lead Zirconate Titanate (PZT-4A) piezoelectric material is determined under various resistance and loading conditions by using the test setup. The commercial FEM software ABAQUS is used to analyze the performance of piezoelectric material under static loading conditions. It is observed that these properties affect the performance of a material particularly in the designing of smart structures. The experimental results are partially compared to the simulation values.

“…In our previous works [20,21], a kind of Nb/Ce co-doped Pb(Zr 0.52 Ti 0.48 )O 3 piezoceramic prepared by a conventional solid-state reaction method has been identified as exhibiting good electrical and mechanical properties, such as a much higher T C than PIC151 (PI Ceramic, Lederhose, Germany) with a similar d 33 [22], and a higher d 33 than PZT-5A with an approached T C [23], as well as a high compression strength and a high fracture toughness. In this work, some material constants and electromechanical coupling parameters were obtained from the systematic analysis of the radial resonance frequency spectra, which is expected to provide a basis for its further study of SHM using EMI technique.…”

In this paper, both the 1D radial mode and the equivalent circuit of a piezoceramic disk resonator were theoretically analyzed based on IEEE standards. And then, the radial resonance frequency spectra of the PZT-based (Nb/Ce co-doped Pb(Zr 0.52 Ti 0.48)O 3 , abbreviated as PZT-NC) piezoceramic circular disks were measured by an impedance analyzer. A set of resonance frequency spectra including six electrical parameters: Z, R, X, Y, G, and B, were used for making a value distinction between three possible resonance frequencies, and between three possible antiresonance frequencies. A new-form Nyquist diagram was depicted to describe the position relations of these characteristic frequencies. Such a complete resonance frequency spectrum was used to perform the accurate calculation of some material constants and electromechanical coupling parameters for the PZT-NC piezoceramics. Further, the frequency dependence of the AC conductive behavior of the specimen was characterized by the complex impedance measurement. The values of AC conductivity at resonance/antiresonance were deduced from the equivalent circuit parameters. Moreover, the Van Dyke circuit model was assigned to each element contribution and the simulated curves showed a nice fitting with the experimental results. Finally, an additional impedance analysis associated with resonance frequency calculation revealed a complicated coupled vibration mode existing in the annular disk specimen.

“…Piezoelectric based harvesters generate a high output voltage; they have a structure without peripheral components, of a lower size and primed for ease of integration in microelectronic devices [1]. In contrast, due to their high impedance, they generate a low amplitude current output and suffer from depolarization [19], brittleness [20], low-temperature operation range [21] and stiffness (high natural frequency of oscillation) [22] requiring larger sizes for low vibration frequencies [23].…”

An energy harvesting device combined with a giant magnetoimpedance (GMI) sensor is presented to analyze low frequency vibrating systems. An electromagnetic harvester based on magnetic levitation is proposed for the electric power generation. The device is composed of two fixed permanent magnets at both ends of a cylindrical frame, a levitating magnet acting as inertial mass and a pick-up coil to collect the induced electromotive force. At the resonance frequency (10 Hz) a maximum electrical power of 1.4 mW at 0.5 g is generated. Moreover, an amorphous wire was employed as sensor nucleus for the design of a linear accelerometer prototype. The sensor is based on the GMI effect where the impedance changes occur as a consequence of the variations of the effective magnetic field due to an oscillating magnetic element. As a result of the magnet’s periodic motion, an amplitude modulated signal (AM) was obtained, its amplitude being proportional to mechanical vibration amplitude (or acceleration). The sensor’s response was examined for a simple ferrite magnet under vibration and compared with that obtained for the vibrational energy harvester. As a result of the small amplitudes of vibration, a linear sensor response was obtained that could be employed in the design of low cost and simple accelerometers.
