Description

The dataset comprises a number of related data sub-sets as follows:

1) Experimental data showing (a) the plot of displacements of a shear piezoelectric plate under different voltage and frequency values, (b) variations of displacement and phase lag versus logarithmic frequency under a voltage of +/-125 V and (c) three examples of typical displacement plots, again under the voltage of +/-125 V.

2) Experimental data and fitting based on the model from Mueller and Zhang (Journal of Applied Physics, 1998, 83 (7), 3754-3761) for varying values of the piezoelectric coefficient 𝑑₁₅ with an electric field, 𝐸1, under different frequencies between 2 Hz and 2 kHz.

3) Experimental data and fitting based on the model from Damjanovic (Physical Review B, 1997, 55(2), R649-R652) to express (a) the low field piezoelectric constant 𝑑_lin(𝑓) and (b) the nonlinear coefficient of piezoelectric constant 𝑑_nl(𝑓).

4) Data showing a) displacements of a piezoelectric actuator for peak-to-peak voltage values in the range 100 V to 640 V and for frequency values from 2 Hz to 2000 Hz and (b) the predicted 3-dimensional plot of such displacement as a function of driving frequency and voltage.

5) Simulated data showing (a) displacements of a single piezoelectric plate at two different driving voltage and three frequency values, (b) resultant displacements from two piezoelectric plates actuated with sinusoidal signals 90°out-of-phase, (c) simulated boundary conditions with different mechanical loads and (d) effect of different load types on piezoelectric displacement.

6) Data showing a) comparison between the measured width at the bottom of a machined groove and the predicted frequency-dependent variation of displacement under the voltage of +/-140 V, (b) SEM images of machined nanogrooves and (c) AFM results of machined grooves.
