| Outline of Final Research Achievements |
Transparent and flexible triboelectric energy harvesters using carbon nanotubes were studied. First, we established a measurement system to evaluate the output characteristics of the device. Then, toward the application to wearable devices, we proposed a device structure that is effective in horizontal vibration while maintaining the thickness of the device and investigated methods to improve the output power, and obtained higher output power for horizontal vibration than conventional structure. We also studied a simple intermittent operation circuit and demonstrated driving a wristwatch.
