| Research Abstract |
In this study, a novel magnetostrictive and piezoelectric hybrid type vibration energy harvester for remote wireless vibration condition monitoring applications was proposed. The feasibility study of the proposed hybrid type vibration energy harvester under the low intensity excitation condition was performed. The vibration energy harvester consists of Terfenol-D and piezocomposite. The intensity of the excitation for experimental evaluation of the proposed vibration energy harvester was 0.71 mm/sec RMS according to ISO standard. The experimentally obtained AC power generation performance of the proposed vibration energy harvester was quite low comparing with the previously developed piezocomposite vibration energy harvester.
