Abstract
Mechanical energy is a versatile and accessible green energy source, increasingly harnessed to power small-scale devices via innovative flexible piezoelectric nanogenerators (F- PNGs). These devices convert mechanical energy into electricity using lightweight materials such as Barium Titanate (BaTiO3), poly dimethyl siloxane (PDMS), and multi-walled carbon nanotubes (MWCNTs). In this design, BaTiO3 nanoparticles were embedded in a composite film with PDMS and MWCNTs, sandwiched between two copper electrodes. The BaTiO3/PDMS/MWCNT composite PENGs, synthesized for this study, produce an output voltage of ∼8 V through periodic cyclic beating. This represents an increase of about 16% compared to the PENGs without MWCNT doping. Additionally, the short-circuit current peaks at about 5.22 μA at the optimal MWCNT wt.%. The electrical energy produced can be efficiently captured by a 0.1μF energy storage capacitor, which is then used to power two commercial red LEDs. These findings suggest that the BaTiO3/PDMS/MWCNT composite holds significant promise as a lead-free piezoelectric nanogenerator for widespread application.
