    Soft robotics take advantage of active materials to regenerate many complex motions, including low-force functions, such as camouflage, micro-grabbing, or agile locomotion of micro robot. 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. In addition, image analysis methodology is discussed and creative ways of analyzing the image data is established.Submission published under a 24 month embargo labeled 'U of I only', the embargo will last until 2017-05-01The student, Kun Hyuck Lee, accepted the attached license on 2015-05-01 at 05:23.The student, Kun Hyuck Lee, submitted this Thesis for approval on 2015-05-01 at 06:12.This Thesis was approved for publication on 2015-05-01 at 15:48.DSpace SAF Submission Ingestion Package generated from Vireo submission #8220 on 2015-07-22 at 14:19:10Made available in DSpace on 2015-07-22T22:34:04Z (GMT).
