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...
