A bio-inspired semi-active vibration isolator with variable-stiffness dielectric elastomer: Design and modeling

•A bio-inspired semi-active vibration isolator is proposed with dielectric elastomers used as the variable stiffness element.•An analytical model for the dielectric elastomer stiffness is developed and validated by the experimental data.•The parametric dependence of the dielectric elastomer stiffnes...
