Outline of Final Research Achievements |
This study proposed/developed a TEG into a multi-layered model, combined it with a PEG to form a PEG-TEG harvester, and demonstrated the improvement of the output voltage by modifying the key factors. We found that our hybrid harvester with the multi-layered TEG can improve the electrical energy output in linear terms under a comparatively small device. Furthermore, the key factors have much influence to generate electrical energy instead of compression force, suggesting that a small force is enough to produce a good result. Our result also showed that this linear improvement is possible due to the increase of vibration amplitude, indicating that amplitude adjustment is important, but it is not directly related to a good electrical performance for initial distance. Finally, the complementary relationship between devices was investigated, and it shows good compatibility.
