Abstract
This paper is concerned with the development of the piezoelectric energy harvesting(PEH) device using Wind. In this study, the piezoelectric energy harvesting system consisting of a cantilever with a pinwheel and piezoelectric wafer was investigated in detail both theoretically and experimentally. The power output characteristics of the PEH was then calculated and discussed. Theoretical and experimental results showed that the PEH was able to charge a battery with ambient vibrations but still needed an effective mechanism which can convert mechanical energy to electrical energy and an optimal electric circuit which dissipates small energy.
