Review and Mechanism of the Thickness Effect of Solid Dielectrics

“…Solid dielectrics of elastomers such as polymerized styrene butadiene rubber, cis-polybutadiene, and polyisoprene rubber are not discussed in this paper [ 35 ]. This is not only because these types of dielectrics have an unstable thickness but also because there are several breakdown mechanisms involved in the failure process aside from electric breakdown [ 36 ], such as thermal breakdown and electro-mechanical breakdown.…”

Recycling of dielectric electroactive materials enabled through thermoplastic PDMS

“…27 For instance, poorly distributed silver causes an inhomogeneous electric field, thereby generating non-equilibrium electrical stresses that cause electromechanical breakdown. 16,28 Furthermore, DEA operation increases temperature, 29 while observed dielectric loss contributes to increased heat generation by transferring mobile charges from silver to the polymer. 30 As a result, the conductivity of the material will be greater, due to the temperature increase, thus resulting in Joule heating, 31 insulation failure 16 and, ultimately, electro-thermal breakdown.…”

Humidity Effect on Dynamic Electromechanical Properties of Polyacrylic Dielectric Elastomer: An Experimental Study

“…Therefore, the electromechanical deformation and stability of DEs is greatly affected, when exposed to the external environment. The researchers have found that the temperature effect plays an important role in determining the static electromechanical actuation of DEs [ 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. During recent years, some scholars also have committed to investigations about humidity effects on the static electromechanical actuation of DEs [ 21 , 22 , 23 , 24 , 25 , 26 ].…”
