Advanced Materials and Structures for Piezoelectric Energy Harvesting

The piezoelectric effect has been well-studied and is considered as a relatively simple and cost-effective approach to harvest energy. Consequently, piezoelectric energy harvesting (PEH) are among the most popular approaches considered for harvesting the mechanical energy. Since PEH is based on the deformation of piezoelectric materials subjected to mechanical force, it is highly rely upon the advancement of materials and structures to improve the conversion efficiency, and therefore the device’s performance in various applications. In recent years many approaches have been developed to advance materials and structures for PEH, including nanomaterials, metamaterials, doping, nanostructures, hybrid-structure, and many others. These advancement present opportunities to apply cross-disciplinary and multi-functional approach in materials and structures for advancing the research of energy harvesting.
