Abstract

 Energy harvesters based on perovskite nanomaterials have garnered significant attention in academia and industry because of their ability to transform mechanical and thermal energies into electric power. These materials have a great deal of promise for capturing body-induced and human activity-induced energy to power implantable and portable low-power devices. This book chapter builds upon previous works that have explored innovative materials and nanotechnologies for fabricating ferroelectric generators. We give a brief overview of flexible piezoelectric and pyroelectric energy harvesters' material selection procedure and reasonable microstructure design. We also stress the unique abilities of perovskite materials as energy collectors in biomedical applications, which include both conventional ferroelectrics and recently developed ferroelectric biomaterials. Additionally, we discuss the newest integration structures of hybrid generators with ferroelectric nanomaterials, which significantly enhance the functionalities of the energy harvesters, particularly for biological and implantable applications.
