Title: | DEVELOPMENT AND ANALYSIS OF DIELECTRIC ELASTOMER ACTUATORS | Authors: | GOH YU FENG | Keywords: | dielectric, elastomer, actuator, | Issue Date: | 8-Mar-2016 | Citation: | GOH YU FENG (2016-03-08). DEVELOPMENT AND ANALYSIS OF DIELECTRIC ELASTOMER ACTUATORS. ScholarBank@NUS Repository. | Abstract: | Electromechanical actuation of dielectric erlastomer actuators (DEA) is limited by electromechanical instability (EMI). We analyse and show that prestretch allows us to achieve giant continuously-tunable actuation. We demonstrate experimentally, that a maximum possible linear actuation strain of 500% is achievable for a VHB DEA. The design is adapted for implementation in tubular DEA for its modularity and robustness compared to a flat sheet DEA. A biomimetic arm prototype design is demonstrated by coupling 2 tubular DEA to form an antagonistic design which eliminates the need for preload. | URI: | http://scholarbank.nus.edu.sg/handle/10635/125244 |
