Dielectric elastomer minimum energy structures (DEMES) are soft electronic transducers
and energy harvesters with potential for consumer goods. The temporal change in their
electromechanical properties is of major importance for engineering tasks. Therefore, we
study acrylic DEMES by impedance spectroscopy and by optical methods for a total time
period of approx. 4.5 months. We apply either compliant electrodes from carbon black
particles only or fluid electrodes from a mixture of carbon black particles and silicone oil …
