Harnessing Vibration Energy from a Piezoelectric Cantilever Beam through a Waist-High Tripod Turnstile and Magnetic Flywheel

Abstract— Searching for energy sources that poses less environmental impact and can be sustained for a certain time leads to renewable energy. Many people are familiar with the usage of ambient renewable energy source, including solar and wind, hence, taking for granted wasted energy sources, such as vibrations. The idea of harvesting energy from any type of vibration, whether it is physically created, mechanically generated, or electromagnetically produced, is now possible due to the discovery of piezoelectric effect. The aim of this study was to harness vibration energy from a piezoelectric cantilever beam through a waist-high tripod turnstile and magnetic flywheel. The prolongation of magnetic flywheel that harnessed and stored electrical energy was also investigated. In this study, the prolongation of rotation of the magnetic flywheel was achievable by multiple actuations in the waist-high tripod turnstile. A maximum increase of storage capacity of 4.455% from an initial storage of 2.563% was harnessed and stored from the setup. The harnessed and stored electrical energy accounted for supplementary source of energy for other primary sources of electrical energy.
