Flexible Magnetocaloric Fiber Mats for Room-Temperature Energy Applications

“…In addition, the application of an external magnetic field modulated the mechanical energy harvesting capabilities, suggesting potential applications in self-powered magnetic field sensing. 44 PDVF-based composites with Gd 5 (Si,Ge) 4 magnetocaloric microparticle inclusions, fabricated by the casting method, were recently studied by Andrade et al with the objective of unlocking the multicaloric potential of such composites. 42 However, uniform dispersion of inclusion particles in the polymer solution has always been a major challenge in the casting method.…”

“…The PVDF film loaded with 5 wt % YFO displayed a substantial polar phase percentage of approximately 85% allowing mechanical energy harvesting. In addition, the application of an external magnetic field modulated the mechanical energy harvesting capabilities, suggesting potential applications in self-powered magnetic field sensing …”

Tuning the Electromechanical Response of P(VDF-TrFE)/ZnSnO3-Based Binary Piezoelectric Composites for Biomechanical Energy-Harvesting and Self-Powered Mechanosensing

“…Other than the piezoelectric performance, a filler with specific functionality can introduce that property into PVDF-based composites too. For example, magnetic fillers can introduce magnetoelectric performance in their PVDF-based composites . Photoactive fillers can introduce the piezo-phototronic activity in their PVDF-based composites .…”

Electroactive properties and piezo-tribo hybrid energy harvesting performances of PVDF-AlFeO3 composites: role of crystal symmetry and agglomeration of fillers

“…For example, the introduction of magnetostrictive fillers into PVDF can introduce magnetoelectric performance into the resulting composite by coupling their magnetostrictive nature with the inherent piezoelectricity of the host polymer matrix. 7 Similarly, if the included filler exhibits good optoelectronic properties, it can induce the piezo-phototronic effect in the resulting PVDF-based composites. 8 Due to the excellent piezoelectric property of PVDF, especially in a flexible form, it has gained tremendous attention in recent times in the field of flexible electronics.…”

“…There have been wideranging attempts to correlate different physiochemical properties of fillers with the output performances of their PVDFbased composites. For this purpose, filler size, 13 shape, 14 chemical states, 15 distribution, 16 functional properties, 7,8 etc. have been widely studied.…”
