<p>Electret-based vibrational energy generators (E-VEGs) have attracted much attention because they can generate electrical power from ambient vibration. The electret is a key material for the E-VEG because the output power of the device is proportional to the square of the surface charge density of the electret. A challenge is that charging process is indispensable for making the electret from a dielectric material, which involves a factor that limits device productivity. To solve this problem, we developed a novel E-VEG that does not require any charging process by utilizing spontaneous orientation of polar organic molecules which have been widely used for organic light-emitting diodes. In this paper, the property and stability of the device are introduced. We believe that the application of polar molecules opens up a new pathway for the development of electret-based devices such as VEGs, sensors, and microphones, etc.</p>
