Do piezoelectric materials have loss determination techniques?
The purpose of this review is to introduce several loss determination techniques for piezoelectric materials. The review starts with brief discussions of the loss factors and of the importance of piezoelectric loss that is related to the antiresonance frequency.
Why are losses important in piezoelectric devices?
A number of studies dealt with the modeling of piezoelectric devices considering complex coefficients of piezoelectric materials. In particular, losses, which are imaginary parameters, are essential because they can reflect the heat dissipation of the device that is a crucial factor for the energy efficiency of such devices.
Are piezoelectric losses a key factor for reducing heat generation?
In particular, recent discoveries by our group show that piezoelectric losses are key factors for reducing heat generation in lead zirconate titanate (PZT)-based piezoelectric resonators with antiresonance operation [ 3 ]. The purpose of this paper is to review the determination methodologies of the loss factors of piezoelectric materials.
What are the three types of loss factors in a piezoelectric device?
Three types of losses (dielectric, elastic, and piezoelectric) are known to be related to the heat dissipation mechanism of piezoelectric materials, therefore obtaining accurate values of the loss factors is essential for minimizing the heat dissipation of piezoelectric devices.
Why are losses important in a ring-dot-type piezoelectric transformer?
In particular, losses, which are imaginary parameters, are essential because they can reflect the heat dissipation of the device that is a crucial factor for the energy efficiency of such devices. Pulpan et al. [ 107] derived analytical models for a ring-dot-type piezoelectric transformer and compared the models to the experimental data.
Can piezoelectric loss be measured using a pulse-echo method?
Though measurements of loss were not considered, the work is meaningful in that it demonstrated the determination of all the piezoelectric-related materials constants using only six (five for the pulse-echo method and one longitudinal piezoelectric bar for resonance and capacitance measurement) samples.
