New type of energy harvester using electric double layer electrets

Shimpei ONO1

In this paper, we propose a new type of “electric double layer electret,” which relies on an electrochemical concept to further increase the output power for vibrational energy harvesters. Thanks to the large capacitance of electric double layer electrets the obtained power can be as high as 1 mW/cm2 even with a low frequency vibration as low as 1 Hz. These results indicate that our energy harvester can be useful to obtain electric power from the vibration of infrastructure, such as bridge and buildings.
