Published: Enhanced FOM in PZT Nanorods for Piezoelectric Energy Harvesting

Our paper entitled “Enhanced Figure of Merit in Pb(Zr,Ti)O3 Nanorods for Piezoelectric Energy Harvesting” has been published in AIP Adv. We experimentally clarified that the effective figure of merit (FOM) of the PZT nanorod array can be enhanced by the decreased density. This approach enables us to independently control the piezoelectric and dielectric constants of materials, making it possible to lower the effective dielectric constant while maintaining the piezoelectric constant. The results indicate that piezoelectric nanorods are a prospective candidate for small-sized PEHs where the cantilever-based PEH cannot be used at a resonant frequency.
