Paper Abstract
Mechanical energy can be converted into electrical energy by using a dielectric elastomer generator. The elastomer is
susceptible to various models of failure, including electrical breakdown, electromechanical instability, loss of tension,
and rupture by stretching. The models of failure define a cycle of maximal energy that can be converted. On the
other hand, when subjected to voltage, the charge will be induced on a dielectric elastomer. When the voltage is
small, the charge increases with the voltage. Along with the continuously increase of voltage, when the charge
approaches a certain value, it would become saturated. This paper develops a thermodynamic model of dielectric
elastomers undergoing polarization saturation. We studied the typical failure model with three variables of Gent
Model silicone energy harvester and obtained an analytical solution of the constitutive equation of dielectric
elastomer undergoing polarization saturation. These results can be used to facilitate the design and manufacture of
dielectric elastomer energy harvesters.
