Characterization of piezoelectric ceramics using the burst/transient method with resonance and antiresonance analysis

et al. 2016

In this paper, a comprehensive methodology for characterizing the high power resonance behavior of bulk piezoelectric ceramics using the burst method is described. In the burst method, the sample is electrically driven at its resonance frequency, and then either a short circuit or an open circuit condition is imposed, after which the vibration decays at the resonance or antiresonance frequency, respectively. This decay can be used to measure the quality factor in either of these conditions. The resulting current in the short circuit vibration condition is related to the vibration velocity through the “force factor.” The generated voltage in the open circuit vibration condition corresponds to the displacement by the “voltage factor.” The force factor and the voltage factor are related to material properties and physical dimensions of the sample. Using this method, the high power behavior of the permittivity, compliance, effective piezoelectric charge constant, electromechanical coupling factor, and material losses can be determined directly by measuring the resonance (short circuit) and antiresonance (open circuit) frequencies, their corresponding quality factors, the force factor A, and the voltage factor B. The experimental procedure to apply this method is described and demonstrated on commercially available hard and semi‐hard PZT materials of k31 geometry.

“…Under resonance drive, not only the piezoelectric coefficient but also the mechanical quality factor, Q m , is important because the amplitude of the piezoelectric vibration is amplified by Q m at the resonance. [19][20][21] Therefore, high-Q m materials such as LiNbO 3 or AlN are more advantageous than a perovskite piezoelectric material such as Pb(Zr, Ti)O 3 from the viewpoint of Q m for the use of a high-frequency resonance drive. 22) Herein, several approaches are presented to increase output.…”

Two types of vibrators using hydrothermally synthesized ferroelectric (K, Na)NbO3 films were fabricated on SrTiO3 substrates. Cantilever piezoelectric vibrators with film thicknesses of 3.5- 22.3 µm were used under low-frequency and no resonance drive. The obtained output displacement increased almost linearly as the film thickness increased under both unipolar and bipolar drives. The obtained transverse piezoelectric coefficient, e 31,f , was almost independent of film thickness, ≈−5 C/m2. On the other hand, a longitudinal piezoelectric vibrator was used under the resonance of half-length longitudinal vibration. The electromechanical coupling factor, K 2, and the mechanical quality factor, Q m, were evaluated. K2 and Q m respectively increased from 0.14% to 1.23% and decreased from 556 to 224 as the film thickness increased from 2.5 to 26 μm. By applying a large voltage of 50 V0-p, a large vibration velocity of 1.5 m/s was obtained for the vibrator with a film thickness of 26 μm.

“…Over the years, quasi-static piezoelectric actuators, in particular multilayer actuators, have gained maturity, finding numerous applications, for example, in aerospace applications. However, although some literature is available on large signal stress-strain behaviour, 1-4 in many cases, the designer still misses essential parameters for describing the behaviour of these actuators, in particular for high-temperature applications. The present work is performed within the project AeroPZT, specifically funded under the Clean Sky Joint Technology Initiative (EU FP7).…”

Investigation of large signal properties of quasi-static lead zirconate titanate actuators at elevated temperature

Quasi-static multilayer piezoelectric actuators are finding more and more applications, for example, in the field of aerospace; however, their properties are still not fully characterised, in particular at a high temperature. The present study targets the full characterisation of both soft-doped and harddoped lead zirconate titanate (PZT) up to 200°C. A simple set of tests and test results are presented, focusing particularly on dielectric losses and creep effect. Dielectric losses were found to decrease with the increasing field for soft-doped PZT, while they tend to increase for hard-doped PZT. The interpretation is that soft-doped PZT has less hysteresis at high field. The creep behaviour is also significantly different. While soft-doped PZT follows a logarithmic model with low and stable creep rates, hard-doped PZT exhibits non-logarithmic creep with increasing or decreasing rates depending on the temperature. This behaviour is attributed to the generation of additional poling in the material.
