Various alternative renewable sources such as solar, wind, thermal energy and
mechanical vibrations are available for the energy generations. For the last decades,
energy harvesters based on piezoelectricity from mechanical vibration are explored
extensively for its functionality in energy technologies [1,2]. Flexible piezoelectric
energy harvesters (FPEHs) and energy storage system were fabricated by employing
solid state synthesized lead-free BZT (BaZr0.2Ti0.8O3) and PZT (PbZr0.52Ti0.48O3)
nanopowders prepared by autocombustion method with polyvinylidene fluoride
(PVDF) in different volume percentage (xBZT/PZT-(1-x)PVDF, x=30, 40, 50).
Both flexible films with quite homogeneous distribution of piezo-active filler were
confirmed by XRD and SEM analysis. In addition, the remnant polarization (Pr) and
dielectric constant are also investigated to evaluate the breakdown strength in
flexible films. The improved dielectric loss tangent (< 0.02) and dielectric
permittivity of 120... at room temperature and frequency 1 MHz of BZT-PVDF (50-
50) in comparison with neat PVDF films is found beneficial for both energy
harvesting and storage. Calculations of storage energies obtained for the investigated
materials revealed an increasing trend with increasing amount of active phase (BZT
and PZT). The maximum storage energy of 0.11 J/cm3 and 0.13 J/cm3, and energy
efficiency (η) of 72% and 39% was obtained for BZT-PVDF (50-50) and PZTPVDF
(40-60) films, respectively. Test of the force impact showing similar output
voltage of around 4 V for both, BZT and PZT flexible films.
