Breaking the Cardiovascular Flow Barrier for Dielectric Elastomer Actuator-Based Pumping: Design and Characterization
This article presents the design and characterization of a high-performance tubular dielectric elastomer pump. The study investigates three distinct pump designs tailored for operation under varying internal pressures of 15, 70, and 120 mmHg. Each pump design is meticulously tested, and the results reveal significant variations in their performance characteristics. The optimal outcomes are achieved with a flow rate of 6.5 L min−1, demonstrating the pump's efficiency in maintaining fluid circulation.
