“…ZnO [3], and a relatively low production cost [4]. PZT materials have been broadly commercialised; for example, a flexible multi-layered composite for low frequency energy harvesting applications was prepared based on PET/Al/PZT/Al/PET [5]. Well-aligned PZT NRs prepared via hydrothermal treatment with (001)-orientated tetragonal single crystalline structures exhibited a high piezoelectric response with a d 33 value of up to 1600 pm·V -1 .…”

“…The piezoelectric current produced with the IDE structure is smaller than the one already obtained with the same PZT with an MIM structure (≈2 μA). That means that the piezoelectric properties of PZT samples with IDE structure are certainly lower than those with MIM electrodes structure.…”

“…The light weight and the weak stiffness of the micro‐generator make it sensitive to air flow. This PZT/Al structure has been thoroughly characterized and shows promising results for energy harvesting under mechanical stress . However, the metal‐insulator‐metal (MIM) structure with full electrodes that has been tested implies a huge capacitance, which limits the obtained electrical energy density.…”

A composite structure with an highly flexible polymer substrate and a thin film of lead zirconate titanate, Pb(Zr,Ti)O3 (PZT), is realized using an all‐chemical process. The fabrication of the structure comprises three steps: first, PZT is deposited on an aluminum thin foil, then the PZT thin film is bonded to a polymer, and, finally, aluminum foil is removed by selective chemical etching. Structural characterization techniques are used to ensure the quality of the PZT/polymer composite structure. Electrical measurements are also performed to confirm the ferroelectric characteristics of the composite. Finally, energy harvesting measurements are realized with interdigitated electrodes structure. A maximal energy density of 20 μJ cm−2 is obtained with manual mechanical excitation and an output voltage up to 35 V under free oscillations conditions in bending mode. This demonstrates that the recently developed PZT/polymer thin films are very promising for low‐frequency vibrating energy‐harvesting applications.

Highly flexible lead zirconate titanate, Pb(Zr,Ti)O 3 (PZT), thin films have been realized by an all chemical process on a plastic substrate. The procedure is composed of three steps: the first one is the PZT deposition on aluminium thin substrate, the second step corresponds to the bonding PZT thin film to a polymer layer and the final step is the aluminium substrate etching. Diffractions and microscopy techniques were used to check the quality of the new PZT/polymer composite structure. Polarization hysteresis and permittivity measurements were also performed to determine the electrical characteristics of the composite. These results demonstrate that the recently developed PZT/polymer thin films are very attractive for both bending actuation and sensing as well as for low frequency vibrating energy harvesting applications.
