Evaluation of the output voltage and amperage of a piezoelectric microgenerator based on HfO2 and ZrO2-doped PVDF

This manuscript aims to evaluate the current and the voltage which would be at the output of a micro generator according to a pressure. The PVDF-based microgenerator modified with hafnia (HfO2) and zircon (ZrO2) nanofillers is sized according to the electrical energy needs of an agricultural sprayer integrated into a soleplate. The microsystem recovers the farmer's pressure energy and then converts it into electrical energy to power the sprayer. It emerges from this study that with a modified PVDF film of dimension 5 x 5 x 0.5 cm, a minimum voltage and amperage of 15 V and 10 amps is obtained, sufficient to power a Geo Tech BP16DH agricultural sprayer. Moreover, PVDF/2HfO2 and PVDF/2ZrO2 composites exhibit the highest voltage and current due to their high piezoelectric coefficient. In short, for high current requirements, it is necessary to opt for the film based on P/2ZO, on the other hand when one wants to optimize the voltage; the ideal would be to choose the film based on P/2HO.

Automated summary

This study aims to evaluate the influence of pressure on the current and voltage output of a microgenerator. The PVDF-based microgenerator modified with hafnia and zircon nanofillers is sized according to the electrical energy needs of an agricultural sprayer. The microsystem is capable of converting the farmer's pressure energy into electrical energy to power the sprayer. The results show that a modified PVDF film with dimensions of 5 x 5 x 0.5 cm can achieve a minimum voltage of 15V and a minimum current of 10 amps, which is sufficient for powering a Geo Tech BP16DH agricultural sprayer. Additionally, PVDF/2HfO2 and PVDF/2ZrO2 composites exhibit the highest voltage and current due to their high piezoelectric coefficient.
