This paper discusses energy harvesting and its application using dielectric elastomer and self-priming circuit。 With the self-priming circuit attached to the dielectric elastomer, the generated voltage increases exponentially according to the variation of the capacitance caused by applied deformation to the elastomer。 Two-stage self-priming circuit is selected for optimal harvesting。 The self-priming harvesting technique is able to increase the voltage of the dielectric elastomer from a few volts to kV order, however in this paper the generated voltage is limited up to lkV in order to avoid the destruction of the dielectric elastomer。 The ability of energy harvesting using dielectric elastomer and self-priming circuit is confirmed by both numerical simulation and experiments。 In the experiment, the dielectric elastomer is deformed by an electric motor, and the harvested energy is stored to a charging capacitor through Zener diodes。 A low-power microcomputer which has a radio transmitter is connected to the charging capacitor for the application example。 The experimental results show that the temperature data can be transmitted only by the harvested energy。 In addition, the efficiency of the energy harvesting is calculated by comparing the generated power with the charged power。
