In this paper, a design methodology for an energy harvesting device will be investigated and results will be presented to
validate the design. The energy harvesting device in the study is 31- unimorph piezoelectric cantilever beam which was
used to convert small amplitude mechanical vibration from a specific machine application into an electrical energy
source that could be used for electronic devices with low power requirements. The primary purpose of the design
methodology is to illustrate a method to design a cantilever beam that is optimized for a particular application. The
methodology will show how the vibration data (frequency and amplitude) from the machine was analyzed and then how
this information was incorporated into the final design of the beam. From the given vibration data a range of frequencies
where the energy harvesting device will generate the greatest amount of energy is determined. The device is then
designed specifically targeting that frequency range. This approach is presented as part of a more general approach to
designing energy harvesters for any application. Also, it will be shown how the thickness and type of materials used for
each layer of cantilever beam were chosen, completely independent of the vibration data, without effecting the over all
optimization process.read more
