The data of the article “Study on the Anomalous Large Bending Behavior of PZT-Based Piezoelectric Monolithic Rectangular Thin Sheets Under Electric Fields”

The specific contents are as follows:Raw plotting data (.txt files) This section contains all underlying source data for generating Figures 1–7 in the main text. Data categories include displacement‑electric field curves (Figure 1), XRD patterns (Figures 2–3), Raman spectra (Figure 4), PFM amplitude and phase measurement results (Figure 5), XPS spectra (Figure 6), and fatigue displacement‑electric field curves (Figure 7).

These data are available for peer reproduction of experimental figures and secondary data mining.Image files (.tif and .png formats) This section includes all high‑resolution composite figures presented in the paper, covering the large electric‑field‑induced bending curves of the 68‑μm‑thick PZT‑based thin sheet (Figure 1), in‑situ XRD patterns of the top and bottom surfaces of the thin sheet under applied electric fields (Figures 2–3), in‑situ Raman spectra of the top and bottom surfaces of the thin sheet under applied electric fields (Figure 4), domain structure and piezoelectric response of the thin sheet cross‑section (Figure 5), XPS spectra of the positive and negative electrode surfaces of the polarized thin sheet (Figure 6), and fatigue displacement‑electric field curves of the thin sheet in a cantilever configuration (Figure 7).
