Piezoelectric energy harvester converting wind aerodynamic energy into electrical energy for microelectronic application

Piezoelectric Energy Harvesting Systems play a vital role in energizing microelectronic devices with the low-frequency operation. Here, novel piezoelectric energy harvesting device has been developed for low power electronic devices. The consists of cantilever poles projecting outwards and cantilevers one end is connected to wind-catcher, another torsional spring. signifies its application placed inwards crystal stack. When wind strikes, vortex created windcatcher, which oscillates generates stress stack develop electric energy. output voltage obtained from does not affect any input frequency crystal. result shows that 120–200 eV 2.9 × 1016–4.84 1016 Hz considering an elementary charge unit as 40 variable flow 4–9 m/s. This research aims efficient wind-based powered
