Energy harvesting is the process of capturing and converting ambient waste energy into useable electricity. Energy harvesters not only solve the concerns related to energy crises, but also endeavor a step towards wireless communication. Energy can be harnessed sufficiently using a variety of ambient sources like solar, mechanical etc. for the development of self powered devices. The mechanical energy has been considered in the present work as it is independent of climatic conditions. The acoustic vibrations from the environment can be efficiently harnessed using piezoelectric cantilevers (PCs). PCs are the devices which convert mechanical vibration to useful voltage using piezoelectric effect. For realization of such system, Lead Zirconium Titanate (PZT) has been chosen as the most suitable candidate having high piezoelectric coefficient which is integrated with non piezoelectric cantilevers. PZT thin film was deposited on nickel (Ni) and silicon (Si) cantilevers using physical deposition technique i.e. Pulsed Laser Deposition (PLD) under the optimized parameters using excimer laser (248 nm) as the ablation source. Ferroelectric properties of PCs indicate the good ferroic properties. The cantilever studies revealed the generation of induced power across the load for the PCs. The cantilever studies were performed for PCs as a function of acceleration and load resistance. The maximum value of power density of 3600 mW/m3 was obtained at 0.5 g acceleration at a load resistance of 100 kΩ.
