Low-cost high performance disposable micropump for fluidic delivery applications

A fully integrated low cost micropump is presented, including actuation, valving, electronics, sensing and control. The unique architecture and electromagnetic pumping technology enables contactless sensing and actuation, which makes it possible to separate the pumping mechanism from the electronic and actuation components. All pump components have been fabricated using conventional techniques to reduce production costs and address its alternative objective for disposable use. The proposed micropump is capable of delivering very high flow rates (170 mL/min) and features closed-loop control for therapies requiring a precise volumetric dosage.
