Electric generation by using dielectric elastomer

Abstract

The purpose of this research is to increase energy density and efficiency of electric generator made by dielectric elastomer (DE). With pure shear loading configuration, the energy density and efficiency was compared by controlling constant voltage and constant current. It was found that the energy density and efficiency with constant current method was higher than those with constant voltage method. Moreover, it was indicated that both the energy density and the efficiency increase with an increase in charging voltage.
