Recent Advances In Piezoelectric Nano generators In Energy Harvesting Applications

Recently, the nanogenerators which can convert the mechanical energy into electricity by using piezoelectric materials have exhibited great potential in microscale power supply and sensor systems. In this paper, i provide a comprehensive review of the research progress in piezoelectric nanogenerators with different material. The fundamental piezoelectric theory and typical piezoelectric materials are firstly reviewed. After that, the working mechanism, modeling, and structure design of different types of piezoelectric nanogenerators were discussed. Then the recent progressof piezoelectric nanogenerators was also reviewed. Finally, i also discussed the potential application and future development of the piezoelectric nanogenerators.
