Short Review about Challenges and Advanced Solutions of Higher Performance Piezoelectric Nanofibers Mats

Piezoelectric nanofibers mats have been received an incremented interest in both research and commercial products for wide energy harvesting applications. Such nanofibers, with diameters less than one micron, can convert the mechanical excitations into electric signals with an improved efficiency according to formed internal electric dipoles along with higher surface-to-volume ratio, compared to bulky polymeric piezo-films. This paper introduces a brief review about the main challenges of piezoelectric nanofibers mats from different aspects including materials and processes. Then, the paper briefly discusses some recent solutions to overcome the challenges facing the piezoelectric polymeric nanofibers through materials additives and processes enhancement which can develop the piezosensitivity of the organic nanofibers.
