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
