Model‐Based Synchronization of Dielectric Elastomers and Membrane Pumps for Performance‐Optimized, Space‐Efficient, and Application‐Specific Pump Design

ABSTRACT This work presents a new approach to designing high‐performance and efficient pumps based on dielectric elastomer actuators. By considering the entire system including load from the beginning of the design process, the advantages of dielectric elastomers are specifically utilized to minimize the required space while optimizing performance within that compact volume. The process is model‐based, ensuring that every aspect, from individual components to the complete system, is carefully optimized for efficiency and power. In the case of the dielectric elastomer, the modeling approach is simplified by restricting it to cases where viscoelastic effects and time‐dependent deformation are not considered. This assumption is justified by the application of clearly defined electromechanical stress limits and the exclusive focus on silicone materials, where such effects are comparatively minor. This approach represents an important step in the use of dielectric elastomer actuators for real‐world applications, as the pump is more powerful over a wide working range compared to the state of the art and can therefore be used in applications where conventional pumps are still commonly employed. Although the pump already achieves mechanical performance comparable to conventional systems, it still lacks custom electronics and a smart, efficiency‐optimized control system to fully leverage the advantages developed in this work. Addressing this gap forms the basis for future research.
