| Summary: | This paper presents work on improving piezoelectric energy harvesters. Harvesting energy from vibrations has received massive attention due to it being a renewable energy source that has a wide range of applications. Over the years of development, there is always research to further improve and optimise piezoelectric energy harvesters. For this paper, the piezoelectric specimen is made of PZT (Lead Zirconate Titanate), brass reinforced and has 31.8mm length, 12.7mm width and 0.511mm thick. An external beam is implemented to provide deflection amplification which in turn increases the output of the energy harvester. Depending on the configuration of the external beam, it can amplify output voltage from 100% to 300%. © (2014) Trans Tech Publications, Switzerland. |
