“…Large-signal: 1 kV unipolar 10 Hz, small-signal 100 V amplitude bipolar, measured within in the same temperature sweep. Figure 13 shows the effective piezoelectric coefficient obtained from the aixACCT aixPES for sample composition E1 [49]. The small signal results are comparable to the resonance data (Error!…”

“…The zero field remanent strain, S min , which is coupled piezoelectrically to the remanent polarisation, drops rapidly at the transition temperature, but the strain at high field persists [3], resulting in a peak in the strain difference and therefore the large signal piezoelectric response. The high temperature materials reported here have high crystal c/a ratio [49][53] and therefore this effect will be particularly pronounced and may explain the very large piezoelectric displacements observed here (in excess of 1000 pm V -1 ) in Figure 13.…”

“…Open and short circuit impedance measurements were used to apply compensation for the parasitic impedances associated with the custom made test fixture and the cabling. Results are shown in Figure 3 for a commercial PZT (Morgan PZT5A4) and a high temperature material, (K Bi)TiO3 -BiFeO3 -PbTiO3 (KBT-BFPT), developed at the University of Leeds [49]. The resonance and anti-resonance are clearly seen in both sets of spectra, with a cut-off at the Curie temperature.…”

Currently available high performance piezoelectric materials, predominantly based on lead zirconate titanate (PZT), are typically limited to operating temperatures of around 200 °C or below. There are many applications in sectors such as automotive, aerospace, power generation and process control, oil and gas, where reliable operation at higher temperatures is required for sensors, actuators and transducers. New materials are being actively developed to meet this need. Development and application of new and existing materials requires reliable measurement of their properties under these challenging conditions. This paper reviews the current state of the art in measurement of piezoelectric properties at high temperature, including direct and converse piezoelectric measurements and resonance techniques applied to high temperature measurements. New results are also presented on measurement of piezoelectric and thermal expansion and the effects of sample distortion on piezoelectric measurements. An investigation of the applicability of resonance measurements at high temperature is presented, and comparisons are drawn between the results of the different measurement techniques. New results on piezoelectric resonance measurements on novel high temperature piezoelectric materials, and conventional PZT materials, at temperatures up to 600 °C are presented.

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.
