Micro-scale to nano-scale generators for energy harvesting: Self powered piezoelectric, triboelectric and hybrid devices (2019, background): “In addition, electrospun nanofibers of flexible PVDF have been examined for a number of energy harvesting applications, which have been recently reviewed [146-148].”
Electrospinning of nanofibers and their applications for energy devices (2015, methodology): “Considering the simultaneous stretching and polarization in one-pot to form NFs, electrospinning is an ideal way to produce β-phase piezoelectric PVDF NFs [114].”
Direct-write PVDF nonwoven fiber fabric energy harvesters via the hollow cylindrical near-field electrospinning process (2014, background): “The typical electric poling requirement for PVDF is higher than 107 V m−1 [5].”
Fabrication of composite PVDF-ZnO nanofiber mats by electrospinning for energy scavenging application with enhanced efficiency (2015, positive): “Single PVDF nanofiber has been entrusted across a couple of electrodes by a near-field electrospinning process to harvest slight mechanical vibration [27] even though, the ensuing nanogenerators only showed very low piezoelectric outputs (up to 30 mVand 3 nA) [1, 31].”
