Energy Harvesting from PZT Pyroelectric Cells

Abstract

PZT pyroelectric elements were designed as thermal energy harvested sources, describing the best technological parameters to achieve large currents. It was demonstrated that currents followed the pyroelectric model for hot air heating. Large voltages were achieved in capacitor electrodes, what allowed charging and storaging energy in 1 muF capacitors. Moreover, it was also demonstrated cell parallel association to provide larger powers to a load
