Power Harvesting and Storage Circuit for a Double Array of Lead-Free Piezoelectric Cantilevers

The purpose of this paper is the studying of an off the shelf solution for power harvesting and storage circuitry for a previously designed lead-free energy harvester. The energy harvester is designed to work at a resonant frequency of 460Hz and consists in a double array of piezoelectric cantilevers (2 × 10) using zinc oxide as a lead-free piezoelectric material. The energy from the harvester is processed by LTC3588, a nanopower energy harvesting power supply.
