“…However, using the (f m , f n ) frequency pair leads to significant errors in the coupling (k) and piezoelectric coefficient (d). While using the (f s , f p ) frequency pair gives reasonable agreement with PRAP for the coupling (k) [37].

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.

“…8), representing an attenuation of the signal by a factor of ffiffi ffi 2 p . RC time constants for PZT at room temperature are typically[100 s [20] (f LL \ 0.01 Hz). The capacitance of a ferroelectric material is also strongly temperature dependent, so the temperature dependence of f LL combines the effects of both capacitance and resistance, providing a useful figure of merit for sensor or transducer applications.…”

Piezoelectric sensors and actuators are a mature technology, commonplace amongst a plethora of industrial fields including automotive, maritime and non-destructive testing. However the environments that these devices are required to serve in are becoming more demanding, with temperatures being driven higher to increase efficiencies and reduce shut-downs. Materials to survive these temperatures have been the focus of many research groups over the last decade, but there still remains no standard for the measurement of piezoelectric materials at high temperature. This is required to effectively determine comparable Figures of Merit into which devices can be successfully designed. As part of a recent European effort to establish metrological techniques for high temperature evaluation of electro-mechanical properties, we present here a review of the most promising high temperature polycrystalline materials. Where their properties allow operation above that of the ubiquitous commercial material lead zirconate titanate, as well as work done to modify a promising high temperature system, for use as a material standard.

“…Several works have been done on the effect of temperature variations on piezoelectric sensors [8,9,10,11,12]. In particular, Hoshyarmamesh et al [7] investigated the real electro-mechanical impedance of deposited thick film piezoelectric sensors on the superalloy blades of a gas turbine compressor used in aerospace at 20 o C and 200 o C in order to detect damage.…”

Ever growing number of space systems raises a question about their safety and longevity. Over time, the complex space environment influences structural materials and electronics affecting mission objectives and performance. In order to determine the effect of space environment on spacecraft's structural condition, material properties and structural interfaces need to be assessed in space. Hence, it is suggested that active non-destructive measurements are employed to provide structural health information to the spacecraft's operator. Electro-mechanical impedance method is a promising approach to SHM of space structures due to its use of small unobtrusive piezoelectric sensors and lightweight hardware. In laboratory settings, this method typically utilizes bulky and heavy instruments, but for mid-frequency bands, a small and lightweight impedance measurement circuit could be built. A miniaturized impedance measurement analyzer was designed and built for applications requiring very small hardware mass. The development was driven by the intention to utilize the miniaturized analyzer for SHM of space structures in orbit. The impedance analyzer was designed and built from off-theshelf components to enable impedance measurements in lower kHz frequency band. It was used to measure the impedance of a payload structure resembling a fixed plate. The aim of this measurement was to demonstrate data acquisition and storage by the miniaturized impedance logger and to compare its performance to laboratory scale instruments. The paper further discusses the effect of space environment on structures, describes and validates an analytical model for a fixedfixed rectangular plate and provides analysis of the potential influence of thermal variation and radiation in space on electro-mechanical impedance signature.
