Vibration Energy Harvester

Vibration energy harvester has been paid a lot of attention by many researchers to transforming ambient vibration into electrical energy, which is normally utilized to develop wireless electronic sectors. The paper presents a finite element model (FEM) of a vibration energy harvester consisting of a bimorph electromechanical system (MEMS) generator. The model is used to simulate, and compare, the mechanical characteristics and electrical response of piezoelectric material results between the cantilever beam structure formed by laminating two piezoelectric layers on both sides of a Carbon fiber reinforced polymer (CFRP) substrate and Ti-6Al-4V substrate using ANSYS®19 R1. A set of numerical simulations has been carried out, and the results show that the comparisons of the harmonic response analysis seen change between the different substrates based on the bimorph piezoelectric MEMS generator.

Monitoring Applications

Rotating machinery is widely used in the industrial plant, for example, power plant, chemical plant, mass-production plant and so on. In order to ensure safety operation of the rotating machinery, vibration condition monitoring of the machinery can play a crucial role. In this study, the cantilever type of vibration energy harvester is designed for vibration condition monitoring applications of rotating machinery. The mechanical resonant frequency of piezoelectric bimorph cantilever will be tuned to the rotating speed of the machinery. Recently, new d31 type Macro-Fiber Composite (MFC) can be commercially available. Due to the d31 configuration, electrical impedance of new MFC is much smaller than that of previous d33 type MFC. This study experimentally compares the ability two types of MFC, d31 and d33 configurations, to generate electrical energy when subjected to mechanical vibration.

Energy harvesting methods that use functional materials have attracted interest because they can take advantage of an abundant but underutilized energy source. Most vibration energy harvester designs operate most effectively around their resonant frequency. However, in practice, the frequency band for ambient vibrational energy is typically broad. The development of technologies for broadband energy harvesting is therefore desirable. The authors previously proposed an energy harvester, called a flexible piezoelectric device (FPED), that consists of a piezoelectric film (polyvinylidene difluoride) and a soft material, such as silicon rubber or polyethylene terephthalate. The authors also proposed a system based on FPEDs for broadband energy harvesting. The system consisted of cantilevered FPEDs, with each FPED connected via a spring. Simply supported FPEDs also have potential for broadband energy harvesting, and here, a theoretical evaluation method is proposed for such a system. Experiments are conducted to validate the derived model.
