Systematic, Scalable Manufacturing Process for Rolled Dielectric Elastomers

Abstract Dielectric elastomers (DEs) have emerged as promising materials for next-generation soft actuators and artificial muscles, due to their remarkable electromechanical properties, such as low power consumption and high energy density. Due to their sensitivity and wide sensing range, they can also be used as sensors. Among various DE configurations, coreless rolled dielectric elastomer actuators (RDEAs) play a significant role due to their unique advantages in terms of manufacturing efficiency and enhanced performance. This contribution presents the innovations and advancements in the scalable manufacturing process of RDEAs. The goal is to be able to produce them more efficiently, with the eventual goal of series production. We have successfully addressed challenges related to uniformity, scalability, and reproducibility, paving the way for RDEAs to become a viable option for large-scale applications and bundling of multiple RDEAs, for example in valve applications and concert subwoofers. This contribution aims to stimulate further research and collaboration in this rapidly evolving field, ultimately contributing to the development of more efficient and versatile soft actuation technologies.
