Optimizing the dielectric elastomer energy harvesting cycles

Abstract

From an electrical point of view dielectric elastomers are variable capacitors, which are frequently used as generators. The focus of this paper is to show, how the maximum energy gain can be realized by realizing an innovative current waveform to charge and discharge the polymer. Several energy harvesting cycles are introduced and their energy output compared. The most promising cycle has been optimized to increase its production while taking several limiting factors into account.
