dc.description.abstract This dissertation describes an approach to harvesting electrical energy from a mechanically excited piezoelectric element. A power supply unit is designed from electrical energy generated by the piezoelectric harvester through various stages to producing significant output voltage. The stages include piezoelectric generator, voltage doubler circuit and voltage regulator circuit. The piezoelectric crystal used in this design is ‘Crystal Unit – HC 49/U 80MHZ which is able to generate about 7.942fv and subsequently doubled to about 14.483fv. The voltage regulator ensures the output from voltage doubler is maintained constant. Experimental results reveal that voltage from the harvester was 82% by the voltage doubler. The results indicate the viability of the piezoelectric power supply unit when compared to conventional power supply unit of the same output range in the market. A stabilize piezoelectric power supply unit with output voltage of14.483fv, and a stabilized voltage of 14.483fv has been successfully designed. en_US
