Overview of the piezoelectric, dielectric, and physical properties of PZT and epoxy.
| | Material | Dielectric constant () | Piezoelectric strain (pC/N) | Dielectric loss () | Young’s modulus (1010 N/m2) | Density (kg/m3) |
| | PZT (APC International, 855, Navy VI) | 3300 (at 1 kHz)—from the manufacturer (606.70—measurement in the lab at the same frequency) | 400/175 | ≤2.50 | 6.4 | 7500 | | Epoxy (Electron Microscopy Sciences, DGEBA, EMS 1232) | 8.239 (at 1 kHz)—from the manufacturer (12.23 from measurement in the lab at the same frequency) | NA/NA | <1 | 0.15–0.20 | 1160 (in wet state) |
