The energy conversion performance of the dielectric elastomer generator (VHB 4905) was investigated with the diaphragm configuration. Under the triangular harvesting scheme, the average energy density and energy conversion efficiency within one electromechanical cycle are measured to be about 102±5 mJ/g and 9.5±2.6 %, respectively. Large proportion of mechanical energy is dissipated via viscosity of the acrylic elastomer material, which implies that the energy conversion performance of DEG is able to be considerably improved by adopting dielectric elastomer material with low viscoelasticity.
