Vibration energy harvesting technologies has attracted a lot of attention over the past decade. Vibration sources such as ocean waves and human motion are potentials providing mechanical energy that can be harvested for charging self-powered wireless sensors or producing electricity.
For this reason, we design a vibration energy conversion power supply, which consists of a VEH with a PVDF piezoelectric thin film planar array vibration structure and an energy harvesting circuit for regulating the electric energy of multiple sources.
This paper have discussioned some parts of the vibration energy harvesting: collection principle, collection method and the energy storage circuit. At present, the research and design of mechanical vibration energy harvesting structures focus on three aspects: broadening the collection frequency band, collecting dimensions and improving efficiency.
The common ground they share serves as a natural motivation for the integration of vibration-based energy harvesting and structural vibration control functions. Fig. 11 presents the general concept and application of dual-function devices. The 2DOF model is a simplified model representing the potential vibration sources.
Energy harvesting devices can also be designed for a combination of vibration controls. In , , , , one of the energy harvesting systems was applied on the vehicle suspension acting as a controllable damper as well as an energy generator (Fig. 27).
Among them, vibration energy is widely available and easy to harvest and is a green energy source. It is usually preferred because of the high output voltage, high power density, and simple configuration of the device.
