| Outline of Final Research Achievements |
Energy harvesting methods that use functional materials have been attracting interest in recent years to take advantage of an abundant but underutilized energy source. Power from the engine vibration, an abundant source of vibration energy, is very attractive from the view point of the energy harvesting.
The authors have proposed a flexible piezoelectric device (FPED), consisting of a piezoelectric film and soft materials. Therefore, we focused on the energy harvesting using the FPED and the engine vibration, and conducted the development of a theoretical evaluation method for the vibration and output power of the FPED and a system using the FPEDs. Validity of the developed theoretical evaluation methods have been verified through the experiments using a shaker and an actual engine vibration. Therefore, a parameter study assuming the engine vibration has been conducted, and the results shows that the energy harvesting system using 10 FPEDs can supply 1 W using the engine vibration.
