The use of piezoelectric materials has been a revolutionary breakthrough in the engineering industry in the past few decades. These materials have been used in many microelectromechanical systems to generate electricity, and the possibilities are endless when it comes to the world of piezoelectric material.When put under stress, piezoelectric materials generate small amounts of electricity. Different systems can be designed in which piezoelectric materials are used efficiently to generate power. This area of study is relatively new, but there is plenty of research that has been previously done on it.In this study, we are trying to use random vibration excitations to generate electricity using a complex gear train involving a double clutch system containing two one-way gears and a cam and follower design that is connected to a piece of piezoelectric material. This design has a spring connected to the follower to store potential energy during a revolution and release that energy as kinetic energy at the end of the revolution. The point of this is to get the piezoelectric material to strike a plastic plectrum, then rise so it can vibrate at a certain resonance frequency. This resonance frequency, when achieved, is the frequency at which the most electricity can be generated. Since we want the optimal amount of electricity, we need the piezoelectric material to strike the plectrum with approximately the same amount of force each time to keep the material vibrating at resonance frequency. Thus, if we can get the material to vibrate constantly at resonance frequency, we can get consistent power generated that can be used elsewhere. The main difference between previous studies and this one is that previous studies used consistent vibration forces attached to their mechanisms to achieve resonance frequency; in this study, we will be using random, more chaotic patterns of vibrations and storing the energy from them in the compression spring attached to the follower.These results were simulated using MATLAB, and the mechanism was animated using Autodesk Inventor Professional 2020. The results found proved that the frequency up conversion effect of the Piezoelectric Energy Harvester generated significantly more power than simply exciting the base of a piezoelectric beam. Design, animation, and simulation of this mechanism are all the goals that were achieved through this study, but future work on a connected circuit to harvest and transform this electricity must be done to store it for use later.
