Piezoelectric energy harvesters of cantilevered beam type are studied in various fields due to simplicity.
In general, these systems obtain electrical energy from mechanical strain by bending of cantilevered beam.
However, conventional systems have disadvantages that they have low efficiency in frequency regions other than resonance frequency.
To overcome the limitations, various energy harvesters to apply performance enhancement strategies are proposed and investigated.
In this paper, a frequency-changeable L shape energy harvester which is form connected cantilever beam and rigid arm is proposed and investigated.
The conventional piezoelectric energy harvester exhibits the principal frequency in the simple bending mode whereas the proposed system features the twisting mode resulting in a higher output voltage than the conventional system.
The proposed energy harvester is simplified to a two-degree-of-freedom model and its dynamics are described.
How the length of a rigid bar affects its natural frequencies is also studied.
To evaluate the performance of the system, experiments by using a vertical shaker and numerical simulation are carried out.
As a result, it is shown that the natural frequency for a twisting mode decreases as the arm length increased, and the higher output voltage is generated comparing with those of the conventional energy harvester.
