The hydrostatic pressure transducers are the essential requirements of high-pressure industries, defense laboratories, power plants, etc. In this regard, we have thoroughly investigated the pressure and temperature dependent dielectric and impedance properties of Pb1-xBi2x/3Zr0.52Ti0.48O3 (PBZT, x=0.05-0.50) electroceramics. Among these compositions, PBZT with x> 0.30 shows composite phase having unreacted ZrO2 in the PBZT perovskite matrix. It is interesting to note that these composites also illustrate well-saturated polarization and ferroelectric phase transition. We have observed nearly 5-10% increase in dielectric constant with varying pressure from 25 MPa to 200 MPa. The pressure sensitivity of these materials is found in the range of 0.10 to 0.50 MPa-1 which is comparable and in some cases better than the reported values in the literature. The change in dielectric constant as a function of applied pressure is taken as an active parameter for sensitivity calculation. These results suggest that the investigated family is a potential candidate for the piezoelectric pressure sensors and transducers. A detail results and discussion will be presented for these compositions as a function of temperature and pressure. We will also explore its suitability as pressure transducers in various industrial applications.
