Power generation of dielectric elastomer generator with diaphragm configuration under triangular harvesting cycle

The energy conversion performance of the dielectric elastomer generator (VHB 4905 acrylic elastomer, 3M) was investigated with the diaphragm configuration. Under the “triangular” harvesting scheme, the average energy density and energy conversion efficiency within one electromechanical cycle are mea...
