Large aspect ratio Ba0.85Ca0.15Zr0.1Ti0.9O3 (BZCT) nanofibers mat was prepared using the electro-spinning technique. Crystal structure analysis confirmed the existence of MPB between tetragonal and rhombohedra phases. The morphology study suggested the formation of discrete nanofibers having a diameter 80–250 nm. Dielectric studies were performed on sintered nanofibers and Curie temperature (TC) was measured at ∼108 °C, which showed a significantly improved TC than that for bulk BCZT particles. The sintered fibers mat was used for fabricating a flexible nanogenerator using room temperature vulcanized silicone elastomer. The open circuit peak voltage was measured ranging from 5.0 to 17.5 V. Peak voltage and power output were found at ∼2.68 V and ∼2.95 μW, respectively, under periodic tapping. The developed BCZT nanofibers mat-based nanogenerator may be applied in wireless microelectronics, energy harvesting devices, and self-powered sensors for structural health monitoring applications.
