For these applications, traditional actuators, like electric motors and combustion engines, are unnecessarily large and heavy. In contrast, electro-active polymers (EAP) such as electrostatically actuated dielectric elastomers (DE) are considered very suitable technologies for these applications. In particular, owing to their simplicity, high strain and energy densities, and low noise, DE’s are currently the most promising candidates for small scale biomimetic applications. In this study, new fiber-constrained DE designs are developed, in order to obtain controlled uniaxial actuation that suits soft robotics and small scale actuation. Also, micro-wrinkle instabilities that occur in fiber-constrained membranes are examined. The property of wrinkle defers by controlling the geometrical parameters and the amount of strain in a membrane. Therefore controlling the shape of wrinkle is applicable for micro-actuation.
