Soft Robotics

In this article, we have demonstrated that a high-performance, bladeless, and valveless soft pump with embedded actuation can be successfully fabricated and actuated to generate flow, using DEAs. The proposed pumping concept is based on an impedance pump mechanism. In addition to the simplicity of its design, its soft and monolithic aspects make it safe, self-contained, and lightweight. The considerable advantages of the proposed pumping concept combined with its high performance (up to 1.35 L/min) make it an attractive candidate for a variety of applications, especially biomedical applications.
