To determine how different mechanical boundary conditions and stiff fiber constraints affect the voltage-induced deformation of dielectric elastomer membranes.
Formulated a theoretical model predicting voltage-induced deformation under equal-biaxial forces, uniaxial forces, and directional displacement constraints.
Tested dielectric elastomer membranes experimentally under equal-biaxial and uniaxial mechanical loading.
Fabricated and evaluated two fiber-constrained membrane architectures: elastomer coated with carbon fibers on both faces and two elastomer sheets sandwiching nylon fibers.
Equal-biaxial forces allow large voltage-induced deformation, whereas unconstrained uniaxial forces permit only minor deformation.
Constraining deformation along one direction with stiff fibers enables substantial voltage-induced expansion in the perpendicular direction, verifying theoretical predictions.
