Paper Abstract

A new array based Electro Activated Polymer (EAP) pump is explored with initial results and design considerations. By developing an array of EAP actuators that are digitally addressable and controlled it is possible to build a pump mechanism with programmable flow rates, pressure, flow direction and multiple flows. This design provides fluid flow by having a continuous pump chamber that consists of multiple voids or cells that are actuated to an open or closed position. When closed the fluid in the cell is displaced by the actuator and forced into the next sequential cell that is open. The unique Pulse Activated Cell System (PACS) array format provides the ability to pump in a programmable X & Y axis. We have targeted the first commercial application as a Programmable Disposable Drug Delivery Platform (PD3P).
