In this paper, some compositions described by the general formula Pb(ZrxTi1-x)0.99Fe0.01O3 have been considered and investigated. The compositions considered have been obtained by solid state reaction technique, where x corresponds to 0.42, 0.52 and 0.58. Sintering has been performed for 2 hours at temperatures between 1100oC and 1250oC. The influence of the sintering temperature on the microstructure and on the hysteresis loops of Fe3+ doped Pb(ZrxTi1-x)O3 system has been investigated. The crystallographic phase and microstucture of the sintered compositions have been studied in detail using X-ray diffraction analysis (XRD) and Scanning Electron Microscopy (SEM). The experimental results obtained by XRD have revealed that all the sintered samples have a perovskite structure. In order to correlate the behavior of the sintered materials to their microscopic structure, the domain structures have been defined by SEM. The dielectric properties, as relative dielectric permittivity (εr) and dielectric loss (tan δ) have been measured. The hysteresis loops at room temperature of all un-poled sintered compositions reveal a similar behaviour with “hard” PZT ceramics. The piezoelectric properties like electromechanical coupling factor (kp) have been investigated after polarization.

Lead zirconate titanate (PZT) piezoelectric ceramics have emerged as a leading material for human motion monitoring and energy harvesting applications due to their exceptional piezoelectric properties, high Curie temperature, and versatility in device fabrication. This review provides a comprehensive overview of the fundamentals of PZT ceramics, including their crystal structure, phase diagram, and the mechanisms underlying their piezoelectric response. The intrinsic and extrinsic contributions to the piezoelectric properties of PZT are discussed, along with the key factors influencing its performance. Various PZT-based devices for human motion monitoring, such as accelerometers, gyroscopes, and pressure sensors, are explored, highlighting their advantages and commercial implementations. Moreover, the application of PZT materials in energy harvesting from human motion is examined, focusing on device configurations, performance metrics, and state--of-the-art PZT energy harvesters. Strategies for enhancing the performance of PZT ceramics and the challenges associated with their use are also addressed. Finally, future research directions are outlined, emphasising the development of lead-free alternatives, advanced manufacturing techniques, and the integration of PZT with other functional materials for multifunctional and self-powered motion monitoring systems.
