As mechanical energy is one of the most abundant energy sources in the ambient environment, vibration-based energy harvesting (VEHs) systems are believed to be the most promising solution for powering small-scale electronic devices with high power densities in ambient environments.
Vibration energy can be collected from various sources such as bridges, buildings, industrial equipment, home appliances, railways, and automobiles. Typically, a vibration energy harvesting system can be modeled as a simple spring-mass model of a linear inertial-based generator, which was developed by Williams and Yates.
Vibrations at the first three resonant modes could be harvested using the method described. Additionally, Chae et al. proposed an electromagnetic energy harvester using an array of rectangular permanent magnets as springless proof mass.
Energy harvesting devices can also be designed for a combination of vibration controls. In one of the energy harvesting systems, it was applied on the vehicle suspension acting as a controllable damper as well as an energy generator.
Low frequency vibration energy is harvested using a cantilever-based energy generator. When excited at 7.36 m/s 2 acceleration amplitude with a frequency of 183.8 Hz, this generator produced an average power of 0.32 μW and a power density of 416 μW/cm 3.
Energy harvesting is the method of extracting electrical energy from ambient sources such as heat, light, and vibration. These sources possess a great amount of energy that can be tapped into.
