Abstract
A 3D printed micropumping system and method is provided. The micropump incorporates an active electromagnetically actuated valve and two Hall effect sensors. Both uniquely added features allowed for better optimization of the pump's parameters through synchronizing the pumping and valve opening motions. This synchronous motion minimized fluid throttling and optimized the pumping stroke versus valve opening onset to realize the maximum possible flow rate and backpressure per consumed power (i.e., high efficiency). The resulting specific flow rates and backpressure were 11.89 ml/min·W and 693 Pa/W at 10V, respectively, the highest reported values at this scale and actuation method. Moreover, the pump's integration to lab-on-chip devices was experimentally verified. The pump's planar and modular design (i.e., versatility), combined with its efficient performance, low driving voltage, and low power consumption, qualifies it as a viable candidate for battery-operated portable point of care diagnostic chips lab-one-chip, and the emerging body-on-chip devices.
