Fostering Piezoelectric Performance of Flexible Nanogenerators using Zn Doped Ba_0.85Ca_0.15Zr_0.1Ti_0.9O₃

Abstract

Recently, flexible piezoelectric generators have attracted an important interest for powering implantable devices. In this work, an environmental-friendly, flexible and efficient piezoelectric generator is demonstrated, based on the use of composite film containing Zn doped (Ba 0.85 Ca 0.15 ) (Ti 0.9 Zr 0.1 )O 3 Zn-(BCZT) nanoparticles embedded into poly(vinylidene fluoride) - co - hexafluoropropylene (PVDF-HFP) polymer. The effect of the Zn doping on the BCZT on the output performance and flexibility were investigated. As a result, the composite film with Zn-(BCZT) exhibits better performance than composite with BCZT., The generator shows maximum peak voltage and power output at 1.83 V and $2,13\ \mu\mathrm{W}$ , respectively, under periodic tapping. The developed piezoelectric generator could open a new application field for using as force sensor.
