Abstract

The performance of a charge-controlled dielectric elastomer membrane is remarkably affected by the leakage current. Based on a charge-controlled dielectric elastomer configuration, this paper presents a theoretical study about the effect of leakage current on the performance of a dielectric elastomer membrane by spraying charge to the two surfaces of DE membrane. It is found that all of the stretch, the charge, and the electric displacement reduce gradually with the time because of the current leakage. The leakage current reduces gradually with the time, and has an abrupt drop in the initial period and becomes gently after a relatively long time. Based on the results of this paper, we have to keep spraying charge to make up the leaked one to maintain the charge-induced stretch.
