We have demonstrated a new type of vibrational energy harvester based on an electret called an electric double layer electret (EDLE) and its application as a vibrational energy harvester. By mechanically modulating the interfacial area between the vibrating electrode and the EDLE, the electrode is electrostatically charged and discharged at different phases and an electric current is generated. Owing to the extremely high density of carriers that accumulate at the EDLE interface, vibrational energy harvesters have the unique capability to electrostatically leverage high-density charge accumulation at the electrode. The power obtained in this study was as high as 10 nJ/cm2 with a resistance of 1 MΩ even with a vibration frequency as low as 1 Hz.
