The piezoelectric poly(vinylidene fluoride‐hexafluoropropylene) ((P(VDF‐HFP)) has been incorporated with zinc oxide (ZnO) of different forms, i.e. nanoparticles (NPs), nanorods (NRs), and microrods (MRs). The polymer has been activated the piezoelectric phase with the poling filed of 70 MV/m at 90°C for 10 min. ZnO of various particle types is grown into piezoelectric wurtzite. The addition of ZnO has slightly changed the degree of crystallinity of the polymers and clearly increased the elasticity to the best value in the case of inserted MRs. The electroactive phase of the polymer‐based film has been enhanced at 2 wt% of ZnO for both NPs and NRs cases. The dielectric constant of the films increased with ZnO concentration. Finally, a cantilever beam structure with the patch of P(VDF‐HFP) reinforced with ZnO of 2 wt% NRs shows the best performance as a microsource of the energy of about 1 µW. Development of micropower energy harvesting in P(VDF‐HFP) with ZnO NRs has been substantially and highly promising to power small‐scale electronics.
