Electro-active polymer actuator based on pre-stretched polyurethane
Dielectric elastomer actuators (DEA) have been studied extensively as it has shown to generate rather promising results in the laboratory for muscle-like actuation. This project investigates how pre-stretching affects the performance of polyurethane (in particular TPU 58887 Elastomer (Estane) and De...

Dielectric elastomer actuators (DEA) have been studied extensively as it has shown to generate rather promising results in the laboratory for muscle-like actuation. This project investigates how pre-stretching affects the performance of polyurethane (in particular TPU 58887 Elastomer (Estane) and Deerfield PT6100S) as a dielectric material in a basic DEA configuration. Pre-stretching seems to affect the actuated area strain both positively and negatively. The optimal pre-stretch percentage for TPU 58887 Elastomer (Estane) and Deerfield PT6100S has been found to be 40% and 15% respectively where the positive effects of pre-stretching outweigh the negative effects. The maximum area strain generated is 3.05% and 0.437% for TPU 58887 (Estane) and Deerfield PT6100S respectively. A higher pre-stretch percentage leads to a higher breakdown strength and a lower breakdown voltage. |
